MultiOrg or Multiple Organizations Architecture allows multiple operating units and their relationships to be defined within a single installation of Oracle Applications. This keeps each operating unit's transaction data separate and secure. Use the following query to determine if MultiOrg is intalled: select multi_org_flag from fnd_product_groups; What is the difference between Fields and FlexFields? A field is a position on a form that one uses to enter, view, update, or delete information. A field prompt describes each field by telling what kind of information appears in the field, or alternatively, what kind of information should be entered in the field. A flexfield is an Oracle Applications field made up of segments. Each segment has an assigned name and a set of valid values. Oracle Applications uses flexfields to capture information about your organization. There are two types of flexfields: key flexfields and descriptive flexfields.

How do I find the list of responsibility assigned to menu. Just the table name will do ? There are two views are involved in this case 1) FND_RESPONSIBILITY_VL 2) FND_MENUS_VL First you have to find the menu_id of the menu from FND_MENUS_VL Then you have to search in the FND_RESPONSIBILITY_VL with the condition of menu_id The query goes like this SELECT responsibility_name FROM FND_RESPONSIBILITY_VL WHERE menu_id = (SELECT menu_id FROM FND_MENUS_VL WHERE user_menu_name LIKE '%MENU_NAME%') 2. How many user is using the given menu ?What is the table name to identify he above relations. The Table to identiy is FND_USER_RESP_GROUPS. From this table, you can get the User_id and then map it with the FND_USER table to get the user name 3. Relation between the menu and form. What is the table name maintain this relation. 4. Can any one tell how many Key FlexFields are there in Oracle Applications and there names with Module name. Run This qury: SELECT fat.application_name, fif.id_flex_name FROM fnd_id_flexs fif JOIN fnd_application_tl fat ON fat.application_id = fif.application_id AND fat.language = 'US' ORDER BY fat.application_name 1. 1.i Suppliers There is more than one account for the same supplier, which one do I choose? Check the supplier site addresses and choose the supplier whose site address matches your invoice address. If none of them match your invoice then ask DP section to create a new site.

A mutating table is a table that is currently being modified by an update. Q)What is the result of comparing NULL with NULL? NULL is neither equal to NULL. . nor it is not equal to NULL. it is considered "mutating" and raises an error since Oracle should not return data that has not yet reached its final state. There are several restrictions in Oracle regarding triggers: • • • A row-level trigger cannot query or modify a mutating table. delete. BEGIN [email protected](TabX).Database A: receives a PL/SQL table from database B CREATE OR REPLACE PROCEDURE pcalled(TabX DBMS_SQL. Etc.do something with TabX from database B null. END. Q)Can one pass an object/table as an argument to a remote procedure? The only way to reference an object type between databases is via a database link. When a trigger tries to reference a table that is in state of flux (being changed). view or cursor. Normally. Any comparison to NULL is evaluated to NULL. NEW and OLD still can be accessed by the trigger) . (Of course. A statement-level trigger cannot query or modify a mutating table if the trigger is fired as the result of a CASCADE delete. Look at this example: [email protected] the workaround is to enforce the referential integrity through triggers as well. Note that it is not enough to just use "similar" type definitions. Oracle users are like database users for any database server such as MySQL. or insert statement. If you must have triggers on tables that have referential constraints. one user is sufficient to full-fill the requirements of a standard web application. Another way this error can occur is if the trigger has statements to change the primary. Q) What is the difference between %TYPE and %ROWTYPE? %ROWTYPE is used to declare a record with the same types as found in the specified database table.VARCHAR2S) IS BEGIN -. Look at this code example to convince yourself. foreign or unique key columns of the table off which it fires. Additional users and their rights over your tablespace can be created and modified from the end-user control panel. %TYPE is used to declare a field with the same type as that of a specified table's column.Page 20 of 259 data. / -.

The various background processes in oracle are a) Data Base Writer(DBWR) :: Data Base Writer Writes Modified blocks from Database buffer cache to Data Files. c) Transaction Control Statements :: Manage change by DML d) Session Control :: Used to control the properties of current session enabling and disabling roles and changing . execute and close 3) What is a Transaction in Oracle 3) A transaction is a Logical unit of work that compromises one or more SQL Statements executed by a single User.This is required since the data is not written whenever a transaction is commited.They do the house keeping activities for the Oracle and are common in any system. Oracle uses an implicit cursor statement for Single row query and Uses Explicit cursor for a multi row query.C. b) Data Manipulation Language(DML) :: The DML statments manipulate database data.There are basically 9 Processes but in a general system we need to mention the first five background processes. e) CheckPoint(CKPT) :: At Specified times.This is useful for recovery from system failure d)Process Monitor(PMON) :: The Process Monitor peforms process recovery when user Process fails. 1) This is one of the most frequently asked question. 17.Set Role e) System Control Statements :: Change Properties of Oracle Instance . c) SavePoint :: For long transactions that contain many SQL statements. d) Rolling Forward :: Process of applying redo log during recovery is called rolling forward. Savepoints can be used to divide a transaction into smaller points. A cursor is basically an area allocated by Oracle for executing the Sql Statement. 2) How many types of Sql Statements are there in Oracle 2) There are basically 6 types of sql statments.5 and Reports 2. Open.Page 27 of 259 16. intermediate markers or savepoints are declared. B C D B C Important Questions in Oracle.g:: Alter System f) Embedded Sql :: Incorporate DDL. b)LogWriter(LGWR) :: LogWriter writes the redo log entries to disk. b) Rollback :: A transaction that retracts any of the changes resulting from SQL statements in Transaction. They are a) Data Defination Language(DDL) :: The DDL statments define and maintain objects and drop objects. . As transaction commits and log buffer fills. Redo Log data is generated in redo log buffer of SGA. e) Cursor :: A cursor is a handle ( name or a pointer) for the memory associated with a specific statement. a transaction begins with first executable statment and ends when it is explicitly commited or rolled back.Fetch.e.g :: Alter Statements.L in Programming Language.5) Oracle 1) What are the Back ground processes in Oracle and what are they.DML and T. 18.g:: Using the Sql Statements in languages such as 'C'. According to ANSI. LGWR writes log entries into online redo log file. Pmon Clears and Frees resources that process was using. all modified database buffers in SGA are written to data files by DBWR at Checkpoints and Updating all data files and control files of database to indicate the most recent checkpoint f) Archives (ARCH) :: The Archiver copies online redo log files to archival storal when they are busy. 4) Key Words Used in Oracle 4) The Key words that are used in Oracle are :: a) Committing:: A transaction is said to be commited when the transaction makes permanent changes resulting from the SQL statements. 20. g) Recoveror(RECO) :: The Recoveror is used to resolve the distributed transaction in network h) Dispatcher (Dnnn) :: The Dispatcher is useful in Multi Threaded Architecture i) Lckn :: We can have upto 10 lock processes for inter instance locking in parallel sql.e.e. Page 28 of 259 f) System Global Area(SGA) :: The SGA is a shared memory region allocated by the Oracle that contains Data and control information for one Oracle Instance. They are basically used for backup when a database crashes. variables and other Package Contents 6) What are Database Triggers and Stored Procedures 6) Database Triggers :: Database Triggers are Procedures that are automatically executed as a result of insert in. h) Redo log Buffer :: Redo log Buffer of SGA stores all the redo log entries. Procedures do not Return values while Functions return one One Value Packages :: Packages Provide a method of encapsulating and storing related procedures. c) Deffered with No Auto Query The operator must navigate to the detail block and explicitly execute a query 10) What are the Different Optimisation Techniques 10) The Various Optimisation techniques are a) Execute Plan :: we can see the plan of the query and change it accordingly based on the indexes . Thus a total of 12 combinations are there and the restriction of usage of 12 triggers has been lifted from Oracle 7.3 Onwards. c) Business Integrity Rules :: The Third Integrity rule is about the complex business processes which cannot be implemented by the above 2 rules. DT are useful for implementing complex business rules which cannot be enforced using the integrity rules. We can have the trigger as Before trigger or After Trigger and at Statement or Row level.update .delete 3 before . functions and Packages 5) Procedures and functions consist of set of PL/SQL statements that are grouped together as a unit to solve a specific problem or perform set of related tasks. g) Program Global Area (PGA):: The PGA is a memory buffer that contains data and control information for server process. They are as follows :: a) Entity Integrity Rule :: The Entity Integrity Rule enforces that the Primary key cannot be Null b) Foreign Key Integrity Rule :: The FKIR denotes that the relationship between the foreign key and the primary key has to be enforced.g:: operations insert. 8) What are the Various Master and Detail Relation ships. 5) What are Procedure.after 3*2 A total of 6 combinatons At statment level(once for the trigger) or row level( for every execution ) 6 * 2 A total of 12. 7) How many Integrity Rules are there and what are they 7) There are Three Integrity Rules. It consists of Database Buffer Cache and Redo log Buffer. b) Deffered with Auto Query Oracle Forms defer fetching the detail records until the operator navigates to the detail block. j) Process :: A Process is a 'thread of control' or mechanism in Operating System that executes series of steps. When there is data in Child Tables the Master tables cannot be deleted. functions. i) Redo Log Files :: Redo log files are set of files that protect altered database data in memory that has not been written to Data Files. The set of database buffers in an instance is called Database Buffer Cache. update to. 9) What are the Various Block Coordination Properties 9) The various Block Coordination Properties are a) Immediate Default Setting. The Detail records are shown when the Master Record are shown. Stored Procedures :: Stored Procedures are Procedures that are stored in Compiled form in the database. or delete from table. Database triggers have the values old and new to denote the old value in the table before it is deleted and the new indicated the new value that will be used. 8) The various Master and Detail Relationship are a) Non Isolated :: The Master cannot be deleted when a child is exisiting b) Isolated :: The Master can be deleted when the child is exisiting c) Cascading :: The child gets deleted when the Master is deleted. g) Database Buffer Cache :: Database Buffer of SGA stores the most recently used blocks of database data. e.The advantage of using the stored procedures is that many users can use the same procedure in compiled and ready to use format. f45run module = my_firstform userid = scott/tiger optimize_sql = No d) Optimize_Tp :: By setting the Optimize_Tp= No.This slow downs the processing because for evertime the SQL must be parsed whenver they are executed. 12)How many types of Exceptions are there 12) There are 2 types of exceptions. When too_many_rows b) User Defined Exceptions e.g. They are a) System Exceptions e.Page 29 of 259 b) Optimizer_hint :: set_item_property('DeptBlock'.'FIRST_ROWS'). b) Share lock .g.Rowid from dept where (Deptno > 25) c) Optimize_Sql :: By setting the Optimize_Sql = No. 20)What is concurrency 20) Cuncurrency is allowing simultaneous access of same data by different users. unique key and primary key 19) Candidate keys are the columns in the table that could be the primary keys and the primary key is the key that has been selected to identify the rows. Select /*+ First_Rows */ Deptno. Locks useful for accesing the database are a) Exclusive The exclusive lock is useful for locking the row when an insert. Oracle Forms assigns seperate cursor only for each query SELECT statement.'2'. All other SQL statements reuse the cursor. Oracle Forms assigns a single cursor for all SQL statements. OOPS supports the concepts of objects and classes and we can consider the peroperty classes as classes and the items as objects 19) What is the difference between candidate key.'Second'Null). The best example is the Property Classes. Here the Null is the else statement where null is done . Views are built using the columns from one or more tables. f45run module = my_firstform userid = scott/tiger optimize_Tp = No 11) How do u implement the If statement in the Select Statement 11) We can implement the if statement in the select statement by using the Decode statement. e.OPTIMIZER_HINT.This lock should not be applied when we do only select from the row. We can categorise the properties by setting the visual attributes and then attach the property classes for the objects.Loc. When no_data_found.update or delete is being done. My_exception exception When My_exception then 13) What are the inline and the precompiler directives 13) The inline and precompiler directives detect the values directly 14) How do you use the same lov for 2 columns 14) We can use the same lov for 2 columns by passing the return values in global values and using the global values in the code 15) How many minimum groups are required for a matrix report 15) The minimum number of groups in matrix report are 4 16) What is the difference between static and dynamic lov 16) The static lov contains the predetermined values while the dynamic lov contains values that come at run time 17) What are snap shots and views 17) Snapshots are mirror or replicas of tables. The Single Table View can be updated but the view with multi table cannot be updated 18) What are the OOPS concepts in Oracle.Dname. Unique key is also useful for identifying the distinct rows in the table.g select DECODE (EMP_CAT.'1'.'First'. 18) Oracle does implement the OOPS concepts. Data for row is stored in a chain of data blocks . There are three types of Segments a) Data Segment :: Non Clustered Table has data segment data of every table is stored in cluster data segment b) Index Segment :: Each Index has index segment that stores data c) Roll Back Segment :: Temporarily store 'undo' information 24) What are the Pct Free and Pct Used 24) Pct Free is used to denote the percentage of the free space that is to be left when creating a table. 21) Previleges and Grants 21) Previleges are the right to execute a particulare type of SQL statements. Parameter Files :: Parameter file is needed to start an instance.They store the data for the database.The grant has to be given by the owner of the object. 23) Physical Storage of the Data 23) The finest level of granularity of the data base are the data blocks. Segments :: Set of Extents allocated for Extents. Read only or abort Reply 27) What is the difference between deleting and truncating of tables 27) Deleting a table will not remove the rows from the table but entry is there in the database dictionary and it can be retrieved But truncating a table deletes it completely and it cannot be retrieved. eg :: If a row has been deleted then the table is said to be mutating and no operations can be done on the table except select. 26) What is a 2 Phase Commit 26) Two Phase commit is used in distributed data base systems.g :: Right to Connect.redo log files and time stamp. Pctused 40 25) What is Row Chaining 25) The data of a row in a table may not be able to fit the same data block. Right to create. e.acme lang Control Files :: Control files record the physical structure of the data files and redo log files They contain the Db name.:: db_block_buffers = 500 db_name = ORA7 db_domain = u. a) System Table space :: This data file stores all the tables related to the system and dba tables b) User Table space :: This data file stores all the user related tables We should have seperate table spaces for storing the tables and indexes so that the access is fast. Data Block :: One Data Block correspond to specific number of physical database space Extent :: Extent is the number of specific number of contigious data blocks.Data Files.Parameter File. Right to resource Grants are given to the objects so that the object might be accessed accordingly. There are basically 2 phases in a 2 phase commit. 29) What are Codd Rules .When a database is created two table spaces are created.To increase the size of the database to store more data we have to add data file. Data Files :: Every Oracle Data Base has one or more physical data files.Page 30 of 259 We can do the table as Share_Lock as many share_locks can be put on the same resource.g. It contains DML statements or Remote Procedural calls that reference a remote object.Once the Data file is created the size cannot change.:: Pctfree 20.s. Similarly Pct Used is used to denote the percentage of the used space that is to be used when creating a table eg. a) Prepare Phase :: Global coordinator asks participants to prepare b) Commit Phase :: Commit all participants to coordinator to Prepared.A parameter file contains the list of instance configuration parameters e. name and location of dbs. 28) What are mutating tables 28) When a table is in state of transition it is said to be mutating. data files . This is useful to maintain the integrity of the database so that all the users see the same values. Control Files 22)Table Space :: The table space is useful for storing the data in the database. 22)Table Space.Every datafile is associated with only one database. 39 ) What are attributes of cursor? %FOUND . %NOTFOUND . 38) what are the datatypes supported By oracle (INTERNAL)? Varchar2. 30) What is Normalisation 30) Normalisation is the process of organising the tables to remove the redundancy. MLSLABEL.There are mainly 5 Normalisation rules. 36) Is space acquired in blocks or extents ? In extents . update. 37) what is clustered index? In an indexed cluster. a) 1 Normal Form :: A table is said to be in 1st Normal Form when the attributes are atomic b) 2 Normal Form :: A table is said to be in 2nd Normal Form when all the candidate keys are dependant on the primary key c) 3rd Normal Form :: A table is said to be third Normal form when it is not dependant transitively 31) What is the Difference between a post query and a pre query 31) A post query will fire for every row that is fetched but the pre query will fire only once. rows are stored together based on their cluster key values . Can not applied for HASH. %ISOPEN. 32) Deleting the Duplicate rows in the table 32) We can delete the duplicate rows in the table by using the Rowid 33) Can U disable database trigger? How? 33) Yes. No RDBMS satisfies all the 12 codd rules and Oracle Satisfies 11 of the 12 rules and is the only Rdbms to satisfy the maximum number of rules. Number. or delete their values. This section describes these pseudocolumns: * CURRVAL * NEXTVAL * LEVEL * ROWID * ROWNUM 35) How many columns can table have? The number of columns in a table can range from 1 to 254.Char .%ROWCOUNT 40) Can you use select in FROM clause of SQL select ? Yes.Page 31 of 259 29) Codd Rules describe the ideal nature of a RDBMS. but is not actually stored in the table. . but you cannot insert. With respect to table ALTER TABLE TABLE [ DISABLE all_trigger ] 34) What is pseudo columns ? Name them? 34) A pseudocolumn behaves like a table column. You can select from pseudocolumns. A reference object automatically inherits any changes that have been made to the source object when you open or regenerate the module that contains the reference object. 4) What are referenced objects? 4) Referencing allows you to create objects that inherit their functionality and appearance from other objects. except that the resulting reference object maintains a link to its source object. Referencing an object is similar to copying an object. except that the resulting reference object maintains a link to its source object.EFFECTIVE_DATE SYSTEM. Referencing an object is similar to copying an object. A reference object automatically inherits any changes that have been made to the source object when you open or regenerate the module that contains the reference object.5 Questions 1) Which trigger are created when master -detail rela? 1) master delete property * NON-ISOLATED (default) a) on check delete master b) on clear details c) on populate details * ISOLATED a) on clear details b) on populate details * CASCADE a) per-delete b) on clear details c) on populate details 2) which system variables can be set by users? 2) SYSTEM.SUPPRESS_WORKING 3) What are object group? 3) An object group is a container for a group of objects. . 5) Can you store objects in library? 5) Referencing allows you to create objects that inherit their functionality and appearance from other objects.DATE_THRESHOLD SYSTEM.Page 32 of 259 Forms 4.MESSAGE_LEVEL SYSTEM. You define an object group when you want to package related objects so you can copy or reference them in another module. Page 33 of 259 6) Is forms 4.5 object oriented tool ? why? 6) yes , partially. 1) PROPERTY CLASS - inheritance property 2) OVERLOADING : procedures and functions. 7) Can you issue DDL in forms? 7) yes, but you have to use FORMS_DDL. Referencing allows you to create objects that inherit their functionality and appearance from other objects. Referencing an object is similar to copying an object, except that the resulting reference object maintains a link to its source object. A reference object automatically inherits any changes that have been made to the source object when you open or regenerate the module that contains the reference object. Any string expression up to 32K: ·a literal · an expression or a variable representing the text of a block of dynamically created PL/SQL code · a DML statement or · a DDL statement Restrictions: The statement you pass to FORMS_DDL may not contain bind variable references in the string, but the values of bind variables can be concatenated into the string before passing the result to FORMS_DDL. 8) What is SECURE property? 8)- Hides characters that the operator types into the text item. This setting is typically used for password protection. 9 ) What are the types of triggers and how the sequence of firing in text item 9) Triggers can be classified as Key Triggers, Mouse Triggers ,Navigational Triggers. Key Triggers :: Key Triggers are fired as a result of Key action.e.g :: Key-next-field, Key-up,Key-Down Mouse Triggers :: Mouse Triggers are fired as a result of the mouse navigation.e.g. When-mouse-buttonpresed,when-mouse-doubleclicked,etc Navigational Triggers :: These Triggers are fired as a result of Navigation. E.g : Post-Text-item,Pre-text-item. We also have event triggers like when –new-form-instance and when-new-block-instance. We cannot call restricted procedures like go_to(‘my_block.first_item’) in the Navigational triggers But can use them in the Key-next-item. The Difference between Key-next and Post-Text is an very important question. The key-next is fired as a result of the key action while the post text is fired as a result of the mouse movement. Key next will not fire unless there is a key event. The sequence of firing in a text item are as follows :: a) pre - text b) when new item c) key-next d) when validate e) post text 10 ) Can you store pictures in database? How? 10)Yes , in long Raw datatype. 11) What are property classes ? Can property classes have trigger? 11) Property class inheritance is a powerful feature that allows you to quickly define objects that conform to your own interface and functionality standards. Property classes also allow you to make global changes to applications quickly. By simply changing the definition of a property class, you can change the definition of all objects that inherit properties from that class. Yes . All type of triggers . * 12 a) If you have property class attached to an item and you have same trigger written for the item . Page 34 of 259 Which will fire first? 12)Item level trigger fires , If item level trigger fires, property level trigger won't fire. Triggers at the lowest level are always given the first preference. The item level trigger fires first and then the block and then the Form level trigger. 13) What are record groups ? * Can record groups created at run-time? 13)A record group is an internal Oracle Forms data structure that has a column/row framework similar to a database table. However, unlike database tables, record groups are separate objects that belong to the form module in which they are defined. A record group can have an unlimited number of columns of type CHAR, LONG, NUMBER, or DATE provided that the total number of columns does not exceed 64K. Record group column names cannot exceed 30 characters. Programmatically, record groups can be used whenever the functionality offered by a two-dimensional array of multiple data types is desirable. TYPES OF RECORD GROUP: Query Record Group A query record group is a record group that has an associated SELECT statement. The columns in a query record group derive their default names, data types, and lengths from the database columns referenced in the SELECT statement. The records in a query record group are the rows retrieved by the query associated with that record group. Non-query Record Group A non-query record group is a group that does not have an associated query, but whose structure and values can be modified programmatically at runtime. Static Record Group A static record group is not associated with a query; rather, you define its structure and row values at design time, and they remain fixed at runtime. 14) What are ALERT? 14)An ALERT is a modal window that displays a message notifiying operator of some application condition. 15) Can a button have icon and lable at the same time ? 15) -NO 16) What is mouse navigate property of button? 16) When Mouse Navigate is True (the default), Oracle Forms performs standard navigation to move the focus to the item when the operator activates the item with the mouse. When Mouse Navigate is set to False, Oracle Forms does not perform navigation (and the resulting validation) to move to the item when an operator activates the item with the mouse. 17) What is FORMS_MDI_WINDOW? 17) forms run inside the MDI application window. This property is useful for calling a form from another one. 18) What are timers ? when when-timer-expired does not fire? 18) The When-Timer-Expired trigger can not fire during trigger, navigation, or transaction processing. 19 ) Can object group have a block? 19)Yes , object group can have block as well as program units. 20) How many types of canvases are there. 20)There are 2 types of canvases called as Content and Stack Canvas. Content canvas is the default and the one that is used mostly for giving the base effect. Its like a plate on which we add items and stacked canvas is used for giving 3 dimensional effect. The following questions might not be asked in an Average Interview and could be asked when the Interviewer wants to trouble u and go deeppppppppppppp……He cannot go further….. 1) What are user-exits? 1) It invokes 3GL programs. 2) Can you pass values to-and-fro from foreign function ? how ? 2) Yes . You obtain a return value from a foreign function by assigning the return value to an Oracle Forms Page 35 of 259 variable or item. Make sure that the Oracle Forms variable or item is the same data type as the return value from the foreign function. After assigning an Oracle Forms variable or item value to a PL/SQL variable, pass the PL/SQL variable as a parameter value in the PL/SQL interface of the foreign function. The PL/SQL variable that is passed as a parameter must be a valid PL/SQL data type; it must also be the appropriate parameter type as defined in the PL/SQL interface. 3) What is IAPXTB structure ? 3) The entries of Pro * C and user exits and the form which simulate the proc or user_exit are stored in IAPXTB table in d/b. 4) Can you call WIN-SDK thruo' user exits? 4) YES. 5) Does user exits supports DLL on MSWINDOWS ? 5) YES . 6) What is path setting for DLL? 6) Make sure you include the name of the DLL in the FORMS45_USEREXIT variable of the ORACLE.INI file, or rename the DLL to F45XTB.DLL. If you rename the DLL to F45XTB.DLL, replace the existing F45XTB.DLL in the \ORAWIN\BIN directory with the new F45XTB.DLL. 7) How is mapping of name of DLL and function done? 7) The dll can be created using the Visual C++ / Visual Basic Tools and then the dll is put in the path that is defined the registery. 8) what is precompiler? 8) It is similar to C precompiler directives. 9) Can you connect to non - oracle datasource ? How? 9) Yes . 10 ) what are key-mode and locking mode properties? level ? 10) Key Mode : Specifies how oracle forms uniquely identifies rows in the database.This is property includes for application that will run against NON-ORACLE datasources . Key setting unique (default.) dateable n-updateable. Locking mode : Specifies when Oracle Forms should attempt to obtain database locks on rows that correspond to queried records in the form. a) immediate b) delayed 11) What are savepoint mode and cursor mode properties ? level? 11) Specifies whether Oracle Forms should issue savepoints during a session. This property is included primarily for applications that will run against non-ORACLE data sources. For applications that will run against ORACLE, use the default setting. Cursor mode - define cursur state across transaction Open/close. 12) Can you replace default form processing ? How ? 13) What is transactional trigger property? 13) Identifies a block as transactional control block. i.e. non - database block that oracle forms should manage as transactional block.(NON-ORACLE datasource) default - FALSE. 14) What is OLE automation ? 14) OLE automation allows an OLE server application to expose a set of commands and functions that can be invoked from an OLE container application. OLE automation provides a way for an OLE container application to use the features of an OLE server application to manipulate an OLE object from the OLE container environment. (FORMS_OLE) Page 36 of 259 15) What does invoke built-in do? 15) This procedure invokes a method. Syntax: PROCEDURE OLE2.INVOKE (object obj_type, method VARCHAR2, list list_type := 0); Parameters: object Is an OLE2 Automation Object. method Is a method (procedure) of the OLE2 object. list Is the name of an argument list assigned to the OLE2.CREATE_ARGLIST function. 16) What are OPEN_FORM,CALL_FORM,NEW_FORM? diff? 16) CALL_FORM : It calls the other form. but parent remains active, when called form completes the operation , it releases lock and control goes back to the calling form. When you call a form, Oracle Forms issues a savepoint for the called form. If the CLEAR_FORM function causes a rollback when the called form is current, Oracle Forms rolls back uncommitted changes to this savepoint. OPEN_FORM : When you call a form, Oracle Forms issues a savepoint for the called form. If the CLEAR_FORM function causes a rollback when the called form is current, Oracle Forms rolls back uncommitted changes to this savepoint. NEW_FORM : Exits the current form and enters the indicated form. The calling form is terminated as the parent form. If the calling form had been called by a higher form, Oracle Forms keeps the higher call active and treats it as a call to the new form. Oracle Forms releases memory (such as database cursors) that the terminated form was using. Oracle Forms runs the new form with the same Runform options as the parent form. If the parent form was a called form, Oracle Forms runs the new form with the same options as the parent form. 17 ) What is call form stack? 17) When successive forms are loaded via the CALL_FORM procedure, the resulting module hierarchy is known as the call form stack. 18) Can u port applictions across the platforms? how? 18) Yes we can port applications across platforms.Consider the form developed in a windows system.The form would be generated in unix system by using f45gen my_form.fmb scott/tiger GUI 1) What is a visual attribute? 1) Visual attributes are the font, color, and pattern properties that you set for form and menu objects that appear in your application's interface. 2) Diff. between VAT and Property Class? imp 2)Named visual attributes define only font, color, and pattern attributes; property classes can contain these and any other properties. You can change the appearance of objects at runtime by changing the named visual attribute programmatically; property class assignment cannot be changed programmatically. When an object is inheriting from both a property class and a named visual attribute, the named visual attribute settings take precedence, and any visual attribute properties in the class are ignored. 3 ) Which trigger related to mouse? 3) When-Mouse-Click When-Mouse-DoubleClick When-Mouse-Down When-Mouse-Enter When-Mouse-Leave When-Mouse-Move When-Mouse-Up Page 37 of 259 4) What is Current record attribute property? 4) Specifies the named visual attribute used when an item is part of the current record. Current Record Attribute is frequently used at the block level to display the current row in a multi-record If you define an item-level Current Record Attribute, you can display a pre-determined item in a special color when it is part of the current record, but you cannot dynamically highlight the current item, as the input focus changes. 5) Can u change VAT at run time? 5) Yes. You can programmatically change an object's named visual attribute setting to change the font, color, and pattern of the object at runtime. 6) Can u set default font in forms? 6) Yes. Change windows registry(regedit). Set form45_font to the desired font. 7) Can u have OLE objects in forms? 7) Yes. 8) Can u have VBX and OCX controls in forms ? 8) Yes. 9) What r the types of windows (Window style)? 9) Specifies whether the window is a Document window or a Dialog window. 10) What is OLE Activation style property? 10) Specifies the event that will activate the OLE containing item. 11) Can u change the mouse pointer ? How? 11) Yes. Specifies the mouse cursor style. Use this property to dynamically change the shape of the cursor. Reports 2.5 1) 1) How many types of columns are there and what are they Formula columns :: For doing mathematical calculations and returning one value Summary Columns :: For doing summary calculations such as summations etc. Place holder Columns :: These columns are useful for storing the value in a variable Can u have more than one layout in report It is possible to have more than one layout in a report by using the additional layout option in the layout editor. Can u run the report with out a parameter form Yes it is possible to run the report without parameter form by setting the PARAM value to Null 2) 2) 3) 3) 4) What is the lock option in reports layout 4) By using the lock option we cannot move the fields in the layout editor outside the frame. This is useful for maintaining the fields . 5) What is Flex 5) Flex is the property of moving the related fields together by setting the flex property on 6) 6) What are the minimum number of groups required for a matrix report The minimum of groups required for a matrix report are 4 1. What is database? A database is a logically coherent collection of data with some inherent meaning, representing some aspect of real world and which is designed, built and populated with data for a specific purpose. What is System R? What are its two major subsystems? System R was designed and developed over a period of 1974-79 at IBM San Jose Research Center. Describe the three levels of data abstraction? The are three levels of abstraction: Ø Physical level: The lowest level of abstraction describes how data are stored. Ø Providing multiple user interfaces. Ø View level: The highest level of abstraction describes only part of entire database. Ø Entity Integrity: States that “Primary key cannot have NULL value” Ø Referential Integrity: States that “Foreign Key can be either a NULL value or should be Primary Key value of other relation. 5. describes what data are stored in database and what relationship among those data. What is extension and intension? Extension It is the number of tuples present in a table at any instance. 9. constructing and manipulating the database for various applications. Intension It is a constant value that gives the name. Advantages of DBMS? Ø Redundancy is controlled. 10. In other words. Ø Enforcing integrity constraints. Ø Security Problems.Page 38 of 259 2. What is a Database system? The database and DBMS software together is called as Database system. Ø Providing backup and recovery. Ø Difficult in accessing data. What is Data Independence? Data independence means that “the application is independent of the storage structure and access strategy of data”. structure of table and the constraints laid on it. Disadvantage in File Processing System? Ø Data redundancy & inconsistency. Define the "integrity rules" There are two Integrity rules. . 6. Ø Data isolation. Ø Concurrent access is not possible. Ø Logical level: The next higher level of abstraction. What is DBMS? It is a collection of programs that enables user to create and maintain a database. Ø Data integrity. 3. This is time dependent. Ø Unauthorised access is restricted. 7. It is a prototype and its purpose was to demonstrate that it is possible to build a Relational System that can be used in a real life environment to solve real life problems. Its two subsystems are Ø Research Storage Ø System Relational Data System. with performance at least comparable to that of existing system. 8. 4. The ability to modify the schema definition in one level should not affect the schema definition in the next higher level. In other words it is general-purpose software that provides the users with the processes of defining. How is the data structure of System R different from the relational structure? Unlike Relational systems in System R Ø Domains are not supported Ø Enforcement of candidate key uniqueness is optional Ø Enforcement of entity integrity is optional Ø Referential integrity is not enforced 11. Hence accounts for logical data independence. What is an Entity type? It is a collection (set) of entities that have same attributes. What is Relationship type? Relationship type defines a set of associations or a relationship set among a given set of entity types. which describes the entity. A relation is defined as a set of tuples. An) is made up of the relation name R and the list of attributes Ai that it contains.. 22.. then it is said to be Weak Entity set. …. . Ø Logical Data Independence: Modification in logical level should affect the view level. These bodies of code are called methods. 26. What is an attribute? It is a particular property. 16. t3. 21. An object contains values stored in instance variables with in the object. that is. What is E-R model? This data model is based on real world that consists of basic objects called entities and of relationship among these objects. .. What is Relationship? It is an association among two or more entities. 17. A2. 24.. What is a view? How it is related to data independence? A view may be thought of as a virtual table. In other words. Each tuple is an ordered list of n-values t=(v1. Objects that contain same types of values and the same methods are grouped together into classes. Entities are described in a database by a set of attributes. 14. 13. Let r be the relation which contains set tuples (t1. there is no stored file that direct represents the view instead a definition of view is stored in data dictionary.Page 39 of 259 Two types of Data Independence: Ø Physical Data Independence: Modification in physical level should not affect the logical level. What is Relationship set? The collection (or set) of similar relationships. 15. What is degree of a Relation? It is the number of attribute of its relation schema. What is Weak Entity set? An entity set may not have sufficient attributes to form a primary key. 23. a table that does not really exist in its own right but is instead derived from one or more underlying base table. Growth and restructuring of base tables is not reflected in views. data relationships data semantics and constraints. 19. Thus the view can insulate users from the effects of restructuring and growth in the database.v2. and its primary key compromises of its partial key and primary key of its parent entity. What is Data Model? A collection of conceptual tools for describing data. An object also contains bodies of code that operate on the object. What is degree of Relationship type? . 27. 20.. What is Object Oriented model? This model is based on collection of objects. 25. What is an Entity? It is a 'thing' in the real world with an independent existence.. tn). What is an Entity set? It is a collection of all entities of particular entity type in the database. vn). NOTE: Logical Data Independence is more difficult to achieve 12. What is an Extension of entity type? The collections of entities of a particular entity type are grouped together into an entity set. t2. 18. What is a Relation Schema and a Relation? A relation Schema denoted by R(A1. What is DDL Interpreter? It interprets DDL statements and record them in tables containing metadata.. What is Record-at-a-time? The Low level or Procedural DML can specify and retrieve each record from a set of records. 35. What is Query evaluation engine? It executes low-level instruction generated by compiler. 25. It consists of a set of operations that take one or two relations as input and produce a new relation.F. What is Functional Dependency? A Functional dependency is denoted by X Y between two sets of attributes X and Y that are subsets of R specifies a constraint on the possible tuple that can form a relation state r of R. 40. Codd. What is Relational Calculus? It is an applied predicate calculus specifically tailored for relational databases proposed by E.e. This retrieve of a record is said to be Record-at-a-time. What is Set-at-a-time or Set-oriented? The High level or Non-procedural DML can specify and retrieve many records in a single DML statement. 36.g. 31. 28.Definition Language? The storage structures and access methods used by database system are specified by a set of definition in a special type of DDL called data storage-definition language. What is Relational Algebra? It is procedural query language. What is DML (Data Manipulation Language)? This language that enable user to access or manipulate data as organised by appropriate data model. 32. This retrieve of a record is said to be Set-at-a-time or Set-oriented.e. variable whose only permitted values are tuples of that relation. What is Data Storage .g. 33. Ø Procedural DML or Low level: DML requires a user to specify what data are needed and how to get those data. How does Tuple-oriented relational calculus differ from domain-oriented relational calculus The tuple-oriented calculus uses a tuple variables i. QUEL The domain-oriented calculus has domain variables i. 27. E. E. 38. deletion and update anomalies. 39. Ø Non-Procedural DML or High level: DML requires a user to specify what data are needed without specifying how to get those data. E. What is DML Compiler? It translates DML statements in a query language into low-level instruction that the query evaluation engine can understand. What is DDL (Data Definition Language)? A data base schema is specifies by a set of definitions expressed by a special language called DDL. What is normalization? It is a process of analysing the given relation schemas based on their Functional Dependencies (FDs) and primary key to achieve the properties Ø Minimizing redundancy Ø Minimizing insertion.Page 40 of 259 It is the number of entity type participating. variables that range over the underlying domains instead of over relation. 26. of languages based on it are DSL ALPHA. QUEL. The constraint is for any two . 29.g. 37. What is SDL (Storage Definition Language)? This language is to specify the internal schema. 34. DEDUCE. This language may specify the mapping between two schemas. What is VDL (View Definition Language)? It specifies user views and their mappings to the conceptual schema.. ILL. 42. 52. Ø A is a prime attribute of R. What is Lossless join property? It guarantees that the spurious tuple generation does not occur with respect to relation schemas after decomposition. 46. 48.Page 41 of 259 tuples t1 and t2 in r if t1[X] = t2[X] then they have t1[Y] = t2[Y]. In other words. What is 5NF? A Relation schema R is said to be 5NF if for every join dependency {R1. What is Fully Functional dependency? It is based on concept of full functional dependency. Ø X is a super key. What is Multivalued dependency? Multivalued dependency denoted by X Y specified on relation schema R.. 50.. It is sometime called as Discriminator. A functional dependency X Y is full functional dependency if removal of any attribute A from X means that the dependency does not hold any more. . This means the value of X component of a tuple uniquely determines the value of component Y. When is a functional dependency F said to be minimal? Ø Every dependency in F has a single attribute for its right hand side. one of following is true Ø X is subset or equal to (or) XY = R. What is BCNF (Boyce-Codd Normal Form)? A relation schema R is in BCNF if it is in 3NF and satisfies an additional constraint that for every FD X A. 45. What is Domain-Key Normal Form? A relation is said to be in DKNF if all constraints and dependencies that should hold on the the constraint can be enforced by simply enforcing the domain constraint and key constraint on the relation. Alternate Key: . one the following is true Ø Ri = R for some i. What is 4NF? A relation schema R is said to be in 4NF if for every Multivalued dependency X Y that holds over R. R2.. artificial.. What is 3NF? A relation schema R is in 3NF if it is in 2NF and for every FD X A either of the following is true Ø X is a Super-key of R. What is 2NF? A relation schema R is in 2NF if it is in 1NF and every non-prime attribute A in R is fully functionally dependent on primary key. Rn} that holds R. over R in which the left side is key of R. Ø The join dependency is implied by the set of FD. 49. What are partial. where X and Y are both subsets of R. specifies the following constraint on any relation r of R: if two tuples t1 and t2 exist in r such that t1[X] = t2[X] then t3 and t4 should also exist in r with the following properties Ø t3[x] = t4[X] = t1[X] = t2[X] Ø t3[Y] = t1[Y] and t4[Y] = t2[Y] Ø t3[Z] = t2[Z] and t4[Z] = t1[Z] where [Z = (R-(X U Y)) ] 43. if every non prime attribute is non-transitively dependent on primary key. 41. X must be a candidate key. compound and natural key? Partial Key: It is a set of attributes that can uniquely identify weak entities and that are related to same owner entity. indivisible) values. Ø We cannot replace any dependency X A in F with a dependency Y A where Y is a proper subset of X and still have a set of dependency that is equivalent to F. 47. 44. Ø We cannot remove any dependency from F and still have set of dependency that is equivalent to F. alternate. What is 1 NF (Normal Form)? The domain of attribute must include only atomic (simple. 51. What is durability in DBMS? Once the DBMS informs the user that a transaction has successfully completed. information about every relation and index that it contains. 61. Inclusion Dependency: An Inclusion Dependency is a statement of the form that some columns of a relation are contained in other columns..A JD {R1. Artificial Key: If no obvious key. What is join dependency and inclusion dependency? Join Dependency: A Join dependency is generalization of Multivalued dependency. What is meant by query optimization? The phase that identifies an efficient execution plan for evaluating a query that has the least estimated cost is referred to as query optimization. Rn is a lossless-join decomposition of R . . A foreign key constraint is an example of inclusion dependency. R2. 59. 58. then it is called the natural key. What are the different phases of transaction? Different phases are . the delay in propagating local information might cause the deadlock detection algorithms to identify deadlocks that do not really exist. 60. 56. It is used when we need to express a relationship among relationships. Types: Ø Binary search style indexing Ø B-Tree indexing Ø Inverted list indexing Ø Memory resident table Ø Table indexing 54. DBMS ensures this by undoing the actions of incomplete transactions. Rn} is said to hold over a relation R if R1. by assigning a unique number to each record or occurrence. R3. 53.. Users should not have to worry about the effect of incomplete transactions. Then this is known as developing an artificial key. then the last resort is to simply create a key. its effects should persist even if the system crashes before all its changes are reflected on disk. either stand alone or compound is available.. the DBMS can reduce the amount of work to be done during restart in the event of subsequent crashes. What is a Phantom Deadlock? In distributed deadlock detection.. This information is stored in a collection of relations maintained by the system called metadata..Page 42 of 259 All Candidate Keys excluding the Primary Key are known as Alternate Keys. . It is also called data dictionary. By taking checkpoints.. What is indexing and what are the different kinds of indexing? Indexing is a technique for determining how quickly specific data can be found. There is no set of sound and complete inference rules for JD. 55. Such situations are called phantom deadlocks and they lead to unnecessary aborts. then combining multiple elements to create a unique identifier for the construct is known as creating a compound key. Aggregation: A concept which is used to model a relationship between a collection of entities and relationships. What is system catalog or catalog relation? How is better known as? A RDBMS maintains a description of all the data that it contains. 57. This property is called durability. Compound Key: If no single data element uniquely identifies occurrences within a construct. What is a checkpoint and When does it occur? A Checkpoint is like a snapshot of the DBMS state. What do you mean by atomicity and aggregation? Atomicity: Either all actions are carried out or none are. Natural Key: When one of the data elements stored within a construct is utilized as the primary key. R2. JOIN: Concatenation of rows from one relation and related rows from another. deletion and modification. and manages space usage within its table-space structures . or nested queries. 71. 74. What are the unary operations in Relational Algebra? PROJECTION and SELECTION. 66. manages memory caches and paging. Brief theory of Network. provides access to them. An RDBMS maintains its own list of authorized users and their associated privileges. its primary functions are storing. dispatches and schedules user requests. What is RDBMS KERNEL? Two important pieces of RDBMS architecture are the kernel.CNUM = ORDER. Columns from the subquery cannot be referenced anywhere else in the parent query. Are the resulting relations of PRODUCT and JOIN operation the same? No. 65. What is a query? A query with respect to DBMS relates to user commands that are used to interact with a data base. Memory Management. and the data dictionary. Storage Management. Depending on how the subquery is written. controls locking for concurrent resource usage. Distribution Control. it can be executed once for the parent query or it can be executed once for each row returned by the parent query. and . Transaction Control. It has no cross-file capabilities but is user-friendly and provides user-interface management. 68. are used to bring back a set of rows to be used by the parent query.

Hierarchical schemas and their properties Network schema uses a graph data structure to organize records example for such a database management system is CTCG while a hierarchical schema uses a tree data structure example for such a system is IMS. A correlated subquery can be easily identified if it contains any references to the parent subquery columns in its WHERE clause. which keeps its Physical Structure hidden from user. which is the software. designed specifically for controlling data access. Which part of the RDBMS takes care of the data dictionary? How Data dictionary is a set of tables and database objects that is stored in a special area of the database and maintained exclusively by the kernel. 63. 70. this is called a correlated subquery. 72.Page 43 of 259 Ø Analysis phase Ø Redo Phase Ø Undo phase 62. What do you mean by flat file database? It is a database in which there are no programs or user access languages. Lock Management 73. What is the job of the information stored in data-dictionary? The information in the data dictionary validates the existence of the objects. What is "transparent DBMS"? It is one. which consists of the system-level data structures used by the kernel to manage the database You might think of an RDBMS as an operating system (or set of subsystems). and securing data. Name the buffer in which all the commands that are typed in are stored ‘Edit’ Buffer 69. Language Processing. The following example demonstrates a non-correlated subquery. PRODUCT: Concatenation of every row in one relation with every row in another. What are the primitive operations common to all record management systems? Addition. What do you mean by Correlated subquery? Subqueries. Logging and Recovery. Name the sub-systems of a RDBMS I/O. The query language can be classified into data definition language and data manipulation language. Security. If the subquery is executed for each row of the parent. 64.g. Process Control.CNUM) 67. How many of these files should a database have at least? Why? Database Files The database files hold the actual data and are typically the largest in size. The database files are fixed in size and never grow bigger than the size at which they were created Control Files The control files and redo logs support the rest of the architecture. The primary difference between SQL and other conventional programming languages is that SQL statements specify what data operations should be performed rather than how to perform them. the location of the database and redo logs. the changes recorded in the redo logs can be used to bring the database to a consistent state without losing any committed transactions. Any database must have at least one control file. 79. 81. Define SQL and state the differences between SQL and other conventional programming Languages SQL is a nonprocedural language that is designed specifically for data access operations on normalized relational database structures. These are Ø Database files Ø Control files Ø Redo logs The most important of these are the database files where the actual data resides. All the files are binary. In the case of non-data loss failure. the redo logs record all changes to the user objects or system objects. Without these files. . the system global area or shared global area. The control files and the redo logs support the functioning of the architecture itself. open. also known as Oracle background processes. the number (or location) of the files is immaterial. LGWR (Log Writer). or backing up and restoring just part of the database. Redo Logs Any database must have at least two redo logs. The data and control structures in the SGA are shareable. How do you communicate with an RDBMS? You communicate with an RDBMS using Structured Query Language (SQL) 77. the tables (and other objects) for all the user accounts can go in one database file—but that's not an ideal situation because it does not make the database structure very flexible for controlling access to storage for different users. What is an Oracle Instance? The Oracle system processes. more than one files are used. the date and time it was created. Every time you add a new database or redo log file to the database. If any type of failure occurs. The control file records the name of the database. Name the three major set of files on disk that compose a database in Oracle There are three major sets of files on disk that compose a database. provide functions for the user processes—functions that would otherwise be done by the user processes themselves Oracle database-wide system memory is known as the SGA. you cannot access the database. These are the journals for the database. Oracle can apply the information in the redo logs automatically without intervention from the DBA. 78. the information is recorded in the control files. In terms of accessing and using the data in the tables and other objects. What are database files. if there is one. putting the database on different disk drives. The combination of the SGA and the Oracle background processes is known as an Oracle instance 80. control files and log files.Page 44 of 259 maps the actual physical storage location. and all the Oracle background processes and user processes can use them. and the synchronization information to ensure that all three sets of files are always in step. and available to Oracle for any data on the database to be useable. although you typically have more than one to guard against loss. The redo log files are fixed in size and never grow dynamically from the size at which they were created. What are the four Oracle system processes that must always be up and running for the database to be useable The four Oracle system processes that must always be up and running for the database to be useable include DBWR (Database Writer). Not only RDBMS takes care of locating data it also determines an optimal access path to store or retrieve the data 76. All three sets of files must be present. and the database administrator might have to recover some or all of the database using a backup. and PMON (Process Monitor). SMON (System Monitor). 75. You must have at least one database file but usually. Depending on their sizes. 85. the exception name is ot_failure. and delete statements against a table. recreates the definitions of objects. Two blocks can have the same block address if they are in different database files. Use of this mechanism enables execution to continue if the error is not severe enough to cause procedure termination. the combination of which uniquely identifies the physical storage location of the row. User accomplishes this by naming an exception as in the following example: ot_failure EXCEPTION. update. the entire block is not available for holding data. The best you can do is recover the database to the time when the export was last performed. What is ROWID? The ROWID is a unique database-wide physical address for every row on every table. After the exception handler executes. 87. For any one table. and inserts the data If Export and Import are used as a means of backing up and recovering the database. Once assigned (when the row is first inserted into the database). Errors cause the program to raise an exception with a transfer of control to the exception-handler block. Each Oracle block is numbered sequentially for each database file starting at 1. The following is an example of a subprogram exception: . This block header has a minimum size. The Import utility reads the file produced by an export. Ø Oracle database file number. Code associated with this handler is written in the EXCEPTION specification area as follows: EXCEPTION when OT_FAILURE then out_status_code := g_out_status_code. The Export utility dumps the definitions and data for the specified part of the database to an operating system binary file. A database trigger can call database procedures that are also written in PL/SQL. it never changes until the row is deleted or the table is dropped. control returns to the block in which the handler was defined. which are use for backup and recovery. User-Defined Exceptions PL/SQL enables the user to define exception handlers in the declarations area of subprogram specifications. Application developers also use it in SQL statements as a quick way to access a row once they know the ROWID 83. Regardless of the block size. In this case. 86. What is Oracle Block? Can two Oracle Blocks have the same address? Oracle "formats" the database files into a number of Oracle blocks when they are first created—making it easier for the RDBMS software to manage the files and easier to read data into the memory areas. Stored procedures are used to reduce network traffic.Page 45 of 259 82. The block size should be a multiple of the operating system block size. Stored procedures are database objects that perform a user defined operation. all the changes made to the database cannot be recovered since the export was performed. control returns to the caller. out_msg := g_out_msg. The trigger can e defined to execute once for the entire statement or once for every row that is inserted. Increasing the Oracle block size can improve performance. but it can grow. but it should be done only when the database is first created. What are stored-procedures? And what are the advantages of using them. Oracle takes up some space to manage the contents of the block. These utilities are Export and Import. which contains the row Ø The row within the block (because each block can hold many rows) The ROWID is used internally in indexes as a quick means of retrieving rows with a particular key value. which contains the block with the rows Ø Oracle block address. The exception handler must be defined within a subprogram specification. Oracle provides two utilities that you can use to back up and restore the database. A stored procedure can have a set of compound SQL statements. or deleted. updated. How are exceptions handled in PL/SQL? Give some of the internal exceptions' name PL/SQL exception handling is a mechanism for dealing with run-time errors encountered during procedure execution. If there are no more executable statements in the block. These Oracle blocks are the smallest unit of storage. Name two utilities that Oracle provides. Along with the RDBMS software. 84. A stored procedure executes the SQL commands and returns the result to the client. The ROWID consists of the following three components. What is database Trigger? A database trigger is a PL/SQL block that can defined to automatically execute for insert. there are twelve events for which you can define database triggers. This technique of raising the exception is used to invoke all user-defined exceptions. System-Defined Exceptions Exceptions internal to PL/SQL are raised automatically upon error. A B C is a set of attributes. 89. PL/SQL does not look only at the referenced name. PL/SQL internal exceptions. NO_DATA_FOUND is a system-defined exception. Tables derived from the ERD a) Are totally unnormalised b) Are always in 1NF c) Can be further denormalised d) May have multi-valued attributes (b) Are always in 1NF 90. Updating tables from join a) i & ii b) ii & iii c) i & iii d) ii & iii (a) i & iii because theta joins are joins made on keys that are not primary keys. RAISE ot_failure. Table below gives a complete list of internal exceptions. The count and data types of formal parameters are also considered. PL/SQL internal exceptions. Within this exception is the RAISE statement that transfers control back to the ot_failure exception handler. Theta joins iii. to resolve a procedure or function call. 88. however.Page 46 of 259 EXCEPTION when NO_DATA_FOUND then g_out_status_code := 'FAIL'. Does PL/SQL support "overloading"? Explain The concept of overloading in PL/SQL relates to the idea that you can define procedures and functions with the same name. 91. To further ensure calling the proper procedure. PL/SQL also attempts to resolve any procedure or function calls in locally defined packages before looking at globally defined packages or internal functions. there is a catch-all exception named OTHERS that traps all errors for which specific error handling has not been established. Exception Name Oracle Error CURSOR_ALREADY_OPEN ORA-06511 DUP_VAL_ON_INDEX ORA-00001 INVALID_CURSOR ORA-01001 INVALID_NUMBER ORA-01722 LOGIN_DENIED ORA-01017 NO_DATA_FOUND ORA-01403 NOT_LOGGED_ON ORA-01012 PROGRAM_ERROR ORA-06501 STORAGE_ERROR ORA-06500 TIMEOUT_ON_RESOURCE ORA-00051 TOO_MANY_ROWS ORA-01422 TRANSACTION_BACKED_OUT ORA-00061 VALUE_ERROR ORA-06502 ZERO_DIVIDE ORA-01476 In addition to this list of exceptions. Prefacing a procedure or function name with the package name fully qualifies any procedure or function reference. Spurious tuples may occur due to i. The functional dependency is as follows AB -> B AC -> C C -> B a) is in 1NF . Bad normalization ii. you can use the dot notation. What is Buffer Manager? It is a program module. The language supports the use two . What is Transaction Manager? It is a program module. In mapping of ERD to DFD a) entities in ERD should correspond to an existing entity/store in DFD b) entity in DFD is converted to attributes of an entity in ERD c) relations in ERD has 1 to 1 correspondence to processes in DFD d) relationships in ERD has 1 to 1 correspondence to flows in DFD (a) entities in ERD should correspond to an existing entity/store in DFD 93. which slows execution. 99. What is Authorization and Integrity manager? It is the program module. this it is not in 3NF. which is responsible for fetching data from disk storage into main memory and deciding what data to be cache in memory. 92. remains in a consistent state despite system failures and concurrent transaction execution proceeds without conflicting. Further B is not functionally dependent on key AC thus it is not in 2NF. C} hence AC is the primary key. 96.the string in single quotes 'NORTH' and 'SOUTH' c) Error . These types of procedures are not available for reference from other Oracle tools.the ORDER BY clause. 100. which manages the allocation of space on disk storage and data structure used to represent information stored on a disk.Page 47 of 259 b) is in 2NF c) is in 3NF d) is in BCNF (a) is in 1NF since (AC)+ = { A. What is Storage Manager? It is a program module that provides the interface between the low-level data stored in database. Another limitation of stand-alone procedures is that they are compiled at run time. What are stand-alone procedures? Procedures that are not part of a package are known as stand-alone because they independently defined.the string should be in double quotes d) Error . Select 'NORTH'. application programs and queries submitted to the system. Since C B is a FD given. What is File Manager? It is a program module. B. A dominant entity is the entity a) on the N side in a 1 : N relationship b) on the 1 side in a 1 : N relationship c) on either side in a 1 : 1 relationship d) nothing to do with 1 : 1 or 1 : N relationship (b) on the 1 side in a 1 : N relationship 94. 97. CUSTOMER From CUST_DTLS Where REGION = 'E' Order By CUSTOMER The above is a) Not an error b) Error . which ensures that database. What are cursors give different types of cursors.ORDER BY clause (d) Error . CUSTOMER From CUST_DTLS Where REGION = 'N' Order By CUSTOMER Union Select 'EAST'. Since ORDER BY clause cannot be used in UNIONS 95. where neither C is a Key nor B is a prime attribute. 101. PL/SQL uses cursors for all database information accesses statements. A good example of a stand-alone procedure is one written in a SQL*Forms application. Thus the given FDs is in 1NF. 98. which tests for the satisfaction of integrity constraint and checks the authority of user to access data. Ø Union or Additive rule: If {X Y. Ø Hot Backup: Some sites (such as worldwide airline reservations systems) cannot shut down the database while making a backup copy of the files.II Determining minimal K for relation schema R. Ø Decomposition rule : If X YZ then X Y. Repeat steps 2 and 3 until Old X+ = X+ Algo. Issue a SQL command to indicate to Oracle. on a tablespace-by-tablespace basis. If (K – A)+ = R then set K = (K – A)+ 105. If a cold backup is performed. given set of FDs F 1. 103. Set Old X+ = X+ 3. For finding the minimal key it is required to find the closure that is the set of all attributes that are dependent on any given set of attributes under the given set of functional dependency. If a data loss failure does occur. Set K to R that is make K a set of all attributes in R 2. i. The database must be running in ARCHIVELOG mode for the hot backup option. Of these the first three are known as Amstrong Rules. So different means of backing up database must be used — the hot backup. dependency preservation states that the closure of the union of the projection of F on each decomposed relation Ri is equal to the closure of F. Once the user has indicated that he/she wants to back up the tablespace files. the lost database files can be restored using the hot backup and the online and offline redo logs created since the backup was done. and control file) when the instance is shut down. that the files of the tablespace are to backed up. What is cold backup and hot backup (in case of Oracle)? Ø Cold Backup: It is copying the three sets of files (database files. . What are Armstrong rules? How do we say that they are complete and/or sound The well-known inference rules for FDs Ø Reflexive rule : If Y is subset or equal to X then X Y. redo logs. Set X+ = X 2.Page 48 of 259 types of cursors Ø Implicit Ø Explicit 102. I Determining X+. closure for X. How can you find the minimal key of relational schema? Minimal key is one which can identify each tuple of the given relation schema uniquely. They are called complete because using these three rules we can generate the rest all inference rules. WY Z} then WX Z. What do you understand by dependency preservation? Given a relation R and a set of FDs F. X Z} then X YZ. The database is restored to the most consistent state without any loss of committed transactions. You must shut down the instance to guarantee a consistent copy. including making changes to the data.. the only option available in the event of data file loss is restoring all the files from the latest backup. he/she can use the operating system to copy those files to the desired backup destination. All work performed on the database since the last backup is lost. Algo. The cold backup is not an available option. Ø Pseudo Transitive rule : If {X Y. This is a straight file copy. Ø Augmentation rule: If X Y then XZ YZ. The users can continue to make full use of the files. given set of FDs F 1. 104. usually from the disk directly to tape. Y Z} then X Z. Compute (K – A)+ with respect to F b. They are sound because it is enough if a set of FDs satisfy these three. For each FD Y Z in F and if Y belongs to X+ then add Z to X+ 4.e. For each attribute A in K a. Ø Transitive rule: If {X Y. Page 49 of 259 ((PR1(F)) U … U (PRn(F)))+ = F+ if decomposition is not dependency preserving. then some dependency is lost in the decomposition. What operator performs pattern matching?

Equi Join: This is the most common type of join which involves only equality comparisions. DELETE FROM EMP. Will the outputs of the above two commands differ? Both will result in deleting all the rows in the table EMP. including tables? Data Definition Language (DDL) 2. ANY are operators in SQL. EXISTS. Retroactive and Simultaneous Update. Which command displays the SQL command in the SQL buffer. !=. 106. 'TROUBLE') FROM DUAL. Here the table name starts with an '&' symbol. What command is used to create a table by copying the structure of another table? Answer : CREATE TABLE . a parent table can be dropped even when a child table exists. What is the value of ‘comm’ and ‘sal’ after executing the following query if the initial value of ‘sal’ is 10000? UPDATE EMP SET SAL = SAL + 1000. AS SELECT command Explanation : To copy only the structure. then all the rows or rows satisfying the condition will be copied to the new table. TROUBLETHETROUBLE 18.1. the WHERE clause of the SELECT command should contain a FALSE statement as in the following. '**'). 20. COMM = SAL*0. Why does the following command give a compilation error? DROP TABLE &TABLE_NAME.'*'.Page 50 of 259 rolled back. '!'). Which function is used to find the largest integer less than or equal to a specific value? FLOOR .'YES'.

ATHEN !!'. CREATE TABLE NEWTABLE AS SELECT * FROM EXISTINGTABLE WHERE 1=2. comm = 1000 25. Answer : NO Explanation : The query checks whether a given string is a numerical digit. 16. Explanation : The query SELECT * FROM EMP ORDER BY ENAME DESC will display the output sorted on ENAME in descending order. 'NO' ). The null values in the commission column will be replaced by 0 and added to salary. If the WHERE condition is true. 22. but TRUNCATE operation cannot be rolled back.'1111111111'). What will be the output of the following query? SELECT DECODE(TRANSLATE('A'. 26. 'AN'..'1234567890'. 19. Variable names should start with an alphabet. What is the use of the DROP option in the ALTER TABLE command? It is used to drop constraints specified on the table. What is the advantage of specifying WITH GRANT OPTION in the GRANT command? The privilege receiver can further grant the privileges he/she has obtained from the owner to any other user. What does the following query do? SELECT SAL + NVL(COMM. This displays the total salary of all employees. What is the use of DESC in SQL? Answer : DESC has two purposes. sal = 11000. 23. What is the use of CASCADE CONSTRAINTS? When this clause is used with the DROP command. 24. Create. Redo Log data is generated in redo log buffer of SGA. Eg: select.5 and Reports 2.

Thus a total of 12 combinations are there and the restriction of usage of 12 triggers has been lifted from Oracle 7.3 Onwards. e. Savepoints can be used to divide a transaction into smaller points. A cursor is basically an area allocated by Oracle for executing the Sql Statement. 4) Key Words Used in Oracle 4) The Key words that are used in Oracle are :: a) Commit :: A transaction is said to be commited when the transaction makes permanent changes resulting from the SQL statements.Fetch.g:: Using the Sql Statements in languages such as 'C'. The set of database buffers in an instance is called Database Buffer Cache. delete 3 before . a transaction begins with first executable statement and ends when it is explicitly commited or rolled back. It consists of Database Buffer Cache and Redo log Buffer. g) Program Global Area (PGA) :: The PGA is a memory buffer that contains data and control information for server process. We can have the trigger as Before trigger or After Trigger and at Statement or Row level. They are basically used for backup when a database crashes.e. functions. update.

Segments :: Set of Extents allocated for Extents. 18) What are the OOPS concepts in Oracle.:: db_block_buffers = 500 db_name = ORA7 db_domain = u. unique key and primary key 19) Candidate keys are the columns in the table that could be the primary keys and the primary key is the key that has been selected to identify the rows. The grant has to be given by the owner of the object. Data Files :: Every Oracle Data Base has one or more physical data files. Every datafile is associated with only one database. When a database is created two table spaces are created. They contain the Db name.redo log files and time stamp. b) Index Segment :: Each Index has index segment that stores data c) Roll Back Segment :: Temporarily stores 'undo' information 24) What are the Pct Free and Pct Used . Locks useful for accessing the database are a) Exclusive The exclusive lock is useful for locking the row when an insert. We can categorize the properties by setting the visual attributes and then attach the property classes for the objects. 18) Oracle does implement the OOPS concepts. Views are built using the columns from one or more tables.s. There are three types of Segments a) Data Segment :: Non Clustered Table has data segment data of every table is stored in cluster data segment. a) System Table space :: This data file stores all the tables related to the system and dba tables b) User Table space :: This data file stores all the user related tables We should have seperate table spaces for storing the tables and indexes so that the access is fast.Page 54 of 259 16) The static lov contains the predetermined values while the dynamic lov contains values that come at run time 17) What are snap shots and views? 17) Snapshots are mirror or replicas of tables. Parameter File. Control Files 22)Table Space :: The table space is useful for storing the data in the database. Right to resource Grants are given to objects so that the objects might be accessed accordingly. The best example is the Property Classes. Data Files. 20) What is concurrency 20) Cuncurrency is allowing simultaneous access of same data by different users. Parameter Files :: Parameter file is needed to start an instance. Data Block :: One Data Block correspond to specific number of physical database space Extent :: Extent is the number of specific number of contiguous data blocks. 23) Physical Storage of the Data 23) The finest level of granularity of the data base are the data blocks. This lock should not be applied when we do only select from the row. The Single Table View can be updated but the view with multi table cannot be updated. data files . Views with joins or grouping expressions cannot be updated. update or delete is being done. e. Once the Data file is created the size cannot change. To increase the size of the database to store more data we have to add data file. A parameter file contains the list of instance configuration parameters e. 22)Table Space. They store the data for the database. Unique key is also useful for identifying the distinct rows in the table. Right to create.g :: Right to Connect. Similarly Pct Used is used to denote the percentage of the used space that is to be used when creating a table eg. Read only or abort Reply 27) What is the difference between deleting and truncating of tables 27) Deleting a table will not remove the rows from the table but entry is there in the database dictionary and it can be retrieved But truncating a table deletes it completely and it cannot be retrieved. a) Prepare Phase :: Global coordinator asks participants to prepare b) Commit Phase :: Commit all participants to coordinator to Prepared.There are mainly 5 Normal rules/forms. 30) What is Normalisation 30) Normalisation is the process of organising the tables to remove the redundancy.Page 55 of 259 24) Pct Free is used to denote the percentage of the free space that is to be left when creating a table. 29) What are Codd Rules 29) Codd Rules describe the ideal nature of a RDBMS. Pctused 40 25) What is Row Chaining 25) The data of a row in a table may not be able to fit in the same data block. a) 1 Normal Form :: A table is said to be in 1st Normal Form when the attributes are atomic. but you cannot insert. 26) What is a 2 Phase Commit 26) Two Phase commit is used in distributed data base systems. There are basically 2 phases in a 2 phase commit. but is not actually stored in the table. It contains DML statements or Remote Procedural calls that reference a remote object. eg :: If a row has been deleted then the table is said to be mutating and no operations can be done on the table except select. With respect to table ALTER TABLE TABLE [ DISABLE all_trigger ] 34) What is pseudo columns ? Name them? 34) A pseudocolumn behaves like a table column. or delete their values. 36) Is space acquired in blocks or extents? In extents . This section describes these pseudocolumns: * CURRVAL * NEXTVAL * LEVEL * ROWID * ROWNUM 35) How many columns can table have? The number of columns in a table can range from 1 to 254. 28) What are mutating tables? 28) When a table is in state of transition it is said to be mutating. This is useful to maintain the integrity of the database so that all the users see the same values. 32) Deleting the Duplicate rows in the table 32) We can delete the duplicate rows in the table by using the Rowid 33) Can U disable database trigger? How? 33) Yes. b) 2 Normal Form :: A table is said to be in 2nd Normal Form when all the candidate keys are dependant on the primary key c) 3rd Normal Form :: A table is said to be third Normal form when it is not dependant transitively 31) What is the Difference between a post query and a pre query 31) A post query will fire for every row that is fetched but the pre query will fire only once. update. Data for row is stored in a chain of data blocks. No RDBMS satisfies all the 12 codd rules and Oracle Satisfies 11 of the 12 rules and is the only Rdbms to satisfy the maximum number of rules. You can select from pseudocolumns.:: Pctfree 20. 1) PROPERTY CLASS . Any string expression up to 32K: · a literal . partially.5 object oriented tool ? why? 6) yes .

What clause do you use to apply updates and deletes to the row currently being addressed. Give an example of the correct syntax to reference a row in a PL/SQL table. What are realms? Application security in Oracle Applications is maintained and managed by assigning responsibilities. The data types of the variables specified in the INTO clause need to correspond with the values returned by the SELECT statement. 57. You can use the explicit cursor attributes to test the success of each fetch before any further references are made to the cursor. Name three things about using cursors with parameters.

What is 1st normal form? Each cell must be one and only one value. List the numbers of all managers who do not hold advanced degrees. UNION will force a sort and cause performance degradation as compared to UNION ALL. so they are faster than BINARY_INTEGER. which are represented internally as 22-byte Oracle numbers. If a SQL statement executes without errors. SELECT c FROM t WHERE c != 'x'. The expr1 can have any datatype and arguments expr2 and expr3 can be of any datatype other than LONG. for example in a loop or record counter. UNION returns distinct rows selected by both queries while UNION ALL returns all the rows. SQLCODE is equal to 0 and SQLERRM contains the string ORA-0000: normal. Also. SQLCODE is equal to 0.

Any number of chararcters or numbers could be between the U and L. List the numbers of all managers who do not hold advanced degrees. or NUMBER operations. What are the benefits of using the PLS_INTEGER Datatype in PL/SQL? If you have a whole-number counter. 99. 94. PLS_INTEGER is the most efficient numeric datatype because its values require less storage than INTEGER or NUMBER values. rtrim('ORACLE UPDATE ') --> 'ORACLE UPDATE' rtrim('ORACLE UPDATE'. ie the first character can be any character.z. 86. consider using a datatype of PLS_INTEGER instead of INTEGER or NUMBER. When is the MINUS keyword used? To remove those rows which are retrieved by one SELECT from those retrieved by another SELECT statement. b.Page 73 of 259 84.

A Better Optimizer 7. the calling procedure must be the earlier of the two. related stored procedures. 123. Granting the privilege to use a package makes all constructs of the package accessible to the grantee. i. Using packages rather than stand–alone stored procedures results in the following improvements:  The entire package is loaded into memory when a procedure within the package is called for the first time. 2. To ease administration burdens (derived from the fact that performing operations on small objects is inherently easier. To take advantage of this index flexibility. you do not have to modify existing applications and business processes.

ON [schema.]table [ [REFERENCING { OLD [AS] old [NEW [AS] new] | NEW [AS] new [OLD [AS] old] } ] FOR EACH ROW [WHEN (condition)] ] pl/sql_block Q105 :At least how many content canvas view you define for each window in your application. Ans. At least one Q106 : Diff type of locking mode are? Ans. 'Immediate' or 'Delayed'. Q107 : Have a Pre-Record trigger that does: IF ((dynamic-condition-is-true) AND :System.Record_Status = 'NEW') Page 93 of 259 THEN RAISE Form_Trigger_Failure; END IF; what is the result of this--Ans. dynamically prevent the user from entering a new record Q108 :How can I dynamically make an entire block query-only at runtime ? Ans. Issue the following : Set_Block_Property('blockname', INSERT_ALLOWED,PROPERTY_OFF); Set_Block_Property('blockname', UPDATE_ALLOWED,PROPERTY_OFF); Q109:What exactly does 'Query Hits' and 'Query Options' mean in the context of a block ? Ans. Set_Block_Property(.., QUERY_HITS) lets your ON-COUNT transactional trigger tell Forms how many records the query out the message :"FRM-xxxxx: Query will retrieve nnn record(s)."Getting this property via Get_Block_Property(.., QUERY_HITS) simply returns the number of records that have been retrieved by the query.Get_Block_Property(.., QUERY_OPTIONS) lets your transactional trigger know whether it's supposed to be doing a normal query, a COUNT(*) type query, or a lock record query. Q110 :What is the difference between the block properties of ARRAY SIZE and RECORDS BUFFERED ? Ans. ARRAY SIZE is the number of records that get fetched each time forms goes to the database. The RECORDS BUFFERED specifies the minimum number of records that should be placed in memory when records are fetched from the database. Even if you specify a low value of 3, the minimum per form is slightly over 300.As more records are brought back from the database (eg records 303-306) they get moved between memory and the file buffer as the user scrolls down. Q111 : Write diff datatypes for a parameter in a form? Ans.Parameters are NUMBER, CHAR, or DATE Q112 : What is the diff between Pre-Query vs. Pre-Select Ans. PRE-QUERY fires just before Forms begins to prepare the SQL statement that will be required to query the appropriate records from the database in response to the query criteria that have been entered into the example record.It is the designers last chance to "deposit" query criteria into the items in the block as if they had been entered into the example record by the operator. PRE-SELECT fires after the PRE-QUERY trigger has fired,and just before the actual, physical construction of the SELECT statement begins. It would typically be used in conjunction with an ON-SELECT trigger in which the designer would be supplanting the normal construction of the SELECT statement with a user exit of his own to construct and prepare the SELECT statement for execution (perhaps against a foreign datasource). Q113 : To store images in the database, you need to read them from the file system in one of the supported standard file formats ,name some of the files? Ans.

SET_FILED_CHAR SRW. SET FILED _DATE 37) Difference between Bind and Lexical parameters? : - this allows you to submit a pre-defined set of requests. Page 113 of 259 BIND VARIABLE : A bind variable is a variable that you declare in a host environment. Bind variables can be used to pass run-time values, either number or character, into or out of one or more PL/SQL programs. The PL/SQL programs use bind variables as they would use any other variable. You can reference variables declared in the host or calling environment in PL/SQL statements, unless the statement is in a procedure, function, or package. This includes host language variables declared in precompiler programs, screen fields in Oracle Developer Forms applications, and iSQL*Plus bind variables. Creating Bind Variables To declare a bind variable in the iSQL*Plus environment, use the command VARIABLE. For example, you declare a variable of type NUMBER and VARCHAR2 as follows: VARIABLE return_code NUMBER VARIABLE return_msg -- are used to replace a single value in sql, pl/sql -- bind variable may be used to replace expressions in select, where, group, order by, having, connect by, start with cause of queries. -- bind reference may not be referenced in FROM clause (or) in place of reserved words or clauses. LEXICAL REFERENCE: -- you can use lexical reference to replace the clauses appearing AFTER select, from, group by, having, connect by, start with. -- you can’t make lexical reference in a pl/sql statmetns. 38) Matrix Report: Simple, Group above, Nested Simple Matrix Report : 4 groups 1.Cross Product Group 2. Row and Column Group 3. Cell Group 4. Cell column is the source of a cross product summary that becomes the cell content. Frames: 1.Repeating frame for rows(down direction) 2.Repeating frame for columns(Across ) 3.Matrix object the intersection of the two repeating frames 39) what is Flex mode and Confine mode? Confine mode On: child objects cannot be moved outside their enclosing parent objects. Off: child objects can be moved outside their enclosing parent objects. Flex mode: On: parent borders "stretch" when child objects are moved against them. Off: parent borders remain fixed when child objects are moved against them. 40) What is Place holder Columns? A placeholder is a column is an empty container at design time. The placeholder can hold a value at run time has been calculated and placed in to It by pl/sql code from anther object. You can set the value of a placeholder column is in a Before Report trigger. Store a Temporary value for future reference. EX. Store the current max salary as records are retrieved. 23) What is Formula Column? A formula column performs a user-defined computation on another column(s) data, including placeholder columns. 24) What is Summary columns? A summary column performs a computation on another column's data. Using the Report Wizard or Data Wizard, you can create the following summaries: sum, average, count, minimum, maximum, % total. You can also create a summary column manually in the Data Model view, and use the Property Palette to create the following additional summaries: first, last, standard deviation, variance. Page 114 of 259 50) What is cursor? A Cursor is a pointer, which works on active set, I.e. which points to only one row at a time in the context area’s ACTIVE SET. A cursor is a construct of pl/sql, used to process multiple rows using a pl/sql block. 28) Types of cursors? 1) Implicit: declared for all DML and pl/sql statements. By default it selects one row only. 2) Explicit: Declared and named by the programmer. Use explicit cursor to individually process each row returned by a Multiple statements, is called ACTIVE SET. Allows the programmer to manually control explicit cursor in the Pl/sql block a) declare: create a named sql area b) Open: identify the active set. c) Fetch: load the current row in to variables. d) Close: release the active set. CURSOR ATTRIBUTES a) %is open: evaluates to true if the cursor is open. b) %not found: evaluates to true if the most recent fetch does not return a row c) %found: evaluates to true if the most recent fetch returns a row. d) %row count: evaluates to the total number of rows returned to far. Example for cursor: 1) Declare Vno emp.empno%type; Vname emp.ename %type; Cursor emp_cursor is Select empno,ename From emp; Begin Open cursor; For I in 1..10 loop Fetch emp_cursor into vno,vname; Dbms_output.putline(to_char(vno) ||’ ‘||vname); End if; E nd; 2) Begin Open emp_cursor; Loop Fetch when emp_cursor % rowcount >10 or Emp_curor % not found; Bdms_output_put_line(to_char(vno)||’ ‘|| vname); End loop; Close emp_cursor; End; CURSOR FOR LOOP A) cursor for loop is a short cut to process explicit cursors B) it has higher performance C) cursor for loop requires only the declaration of the cursor, remaining things like opening, fetching and close are automatically take by the cursor for loop Example: 1) Declare Cursor emp_cursor is Select empno,ename From emp; Begin putline(emp_record.Page 115 of 259 For emp_record in emp_cursor loop Dbms_output. ename FROM emp) LOOP -.implicit close occurs END.conversion. 8) to_many_row ---------single row select returned more than one row. 4) Invalid_number -------. .attempted to divided by zero.pl/sql ran out of memory or memory is corrupted.putline(emp_record. 6) program_error -------.

This combination of the SGA and the Oracle processes is called an Oracle instance. The execution file is a SQL script. and suggest you use either a PL/SQL Stored Procedure or a Spawned C Program instead. The Instance and the Database After starting an instance.

Referential integrity requires that the value of every foreign key in every table be matched by the value of a primary key in another table. adv: 1.sql % found: returns boolean value stating whether the record is found in the cursor. Views present a different representation of the data that resides within the base tables. note: data which is populated into the cursor is known as active dataset.of rows executed in the cursor.sql %rowcount :returns a pneumeric value stating no.sql%is open:attribute returns a boolean value stating wether the cursor is open or closed. Views are very powerful because they allow you to tailor the presentation of data to different types of users. the database administrator can shut down the database so that it is closed. When a database is closed. 3. What is a cursor? cursor is a private sql work area used to perform manipulations on data using pl\sql. a view is defined by a query that extracts or derives data from the tables the view references. . users cannot access the information that it contains. 2. In clustered and massively parallel systems (MPP). the Oracle Parallel Server allows multiple instances to mount a single database.mainly used for multiple row manipulations and locking columns. a view is not allocated any storage space.explicit implicit ——— attributes or properties for implicit cursor 1. Normal users do not have control over the current status of an Oracle database. Views are often used to: • provide an additional level of table security by restricting access to a predetermined set of rows and/or columns of a table • hide data complexity • simplify commands for the user • present the data in a different perspective from that of the base table • isolate applications from changes in definitions of base tables • express a query that cannot be expressed without using a view Q:What is referential integrity? Rules governing the relationships between primary keys and foreign keys of tables within a relational database that determine data consistency. These tables are called base tables. Only the database administrator can start up an instance and open the database. It is available locally only on CMS and PCs with oracle version 5. we can create ddl trigger. WE CAN WRITE TWO CURSORS IN ONE PROGRAM WE CAN WRITE A CURSOR SPECIFYING PARAMETERS CURSOR WITH UPDATE CLAUSE IS USED TO PERFORM LOCKS ON DATA. ODL loads the table from a control file and separate fixed format data file.startoff). 1.% is open 2. SQL * Loader is much more flexible than ODL and will eventually supersede it on all systems. for Example : insert into CAR values(…) where the values to be inserted into a row of the table are listed inside the parentheses. We can execute a function in sql query select functionname(paramaters) from dual.user_objects Question:Why Use Sql* Loader in Oracle Database? Answer: The Sql Loader module of the oracle database Management System loads data into an existing ORACLE table from an external files.

It also eliminates the need to recompile components when minor changes occur to the database. or delete their values. or SQL> delete duplicate_values_field_name dv from table_name ta where rowid < (select min(rowid) from table_name tb where ta. A synonym is an alternative name for tables. How do I eliminate duplicate rows in an Oracle database? SQL> delete from table_name where rowid not in (select max(rowid) from table group by duplicate_values_field_name). you can name these exceptions using PRAGMA EXCEPTION_INIT 4)Unnamed programmer-defined exceptions. 1.ROWID. 2.dv). In oracle there are serveral types of exceptions 1) Pre-defined exceptions like NO_DATA_FOUND.LEVEL what is a schema ? A schema is a oracle database user account. What is the difference of a LEFT JOIN and an INNER JOIN statement? Expected answer: A LEFT JOIN will take ALL values from the first declared table and matching values from the second . but you cannot insert. but is not actually stored in the table. The result set of a three table Cartesian product will have x * y * z number of rows where x.procedures and other database objects generally when we have more than one schema and we wish to access an object of a different schema then we create synonyms for that object in the schema where we wish to access the object. You can select from pseudocolumns. What are pseudo-columns in SQL? Provide examples? A pseudocolumn behaves like a table column.views. It is causes by specifying a table in the FROM clause without joining it to another table. How do you view version information in Oracle? SQL> select banner from $version. z correspond to the number of rows in each table involved in the join.

Exceptions that are defined and raised in the server by the programmer. y..object-name what is an exception ? Exception is an event that causes suspension of normal program execution. What is an advantage to using a stored procedure as opposed to passing an SQL query from an application. Expected answer: A stored procedure is pre-loaded in memory for faster execution. and raises that exception with a call to RAISE_APPLICATION_ERROR.NEXTVAL. update. Examples: CURRVAL. In this case. What is a Cartesian product? What causes it? Expected answer: A Cartesian product is the result of an unrestricted join of two or more tables. 3.TOO_MANY_ROWS 2) User-defined exceptions which would validate the business logic 3) unnamed system exceptions which are raised due to errors in the application code . DBMS_LOCK. When is a declare statement needed ? The DECLARE statement is used in PL/SQL anonymous blocks such as with stand alone. In Oracle 8 they will be able to be of the %ROWTYPE designation. DBMS_ALERT. It must come first in a PL/SQL stand alone file if it is used. Expected answer : Candidate should mention use of DECLARE statement. What packages (if any) has Oracle provided for use by developers? Expected answer: Oracle provides the DBMS_ series of packages. great. There are many which developers should be aware of such as DBMS_SQL. Describe the use of %ROWTYPE and %TYPE in PL/SQL Expected answer: %ROWTYPE allows you to associate a variable with an entire table row. 5. DBMS_UTILITY. 4. 8. It occurs because the trigger is trying to update a row it is currently using. DBMS_DDL. DBMS_JOB. 3.Page 125 of 259 declared table based on the column the join has been declared on. 7. UTL_FILE. What are SQLCODE and SQLERRM and why are they important for PL/SQL developers? Level: Intermediate . Describe the use of PL/SQL tables Expected answer: PL/SQL tables are scalar arrays that can be referenced by a binary integer. The %TYPE associates a variable with a single column type. If not specified in this order will result in the final return being done twice because of the way the %NOTFOUND is handled by PL/SQL. In what order should a open/fetch/loop set of commands in a PL/SQL block be implemented if you use the %NOTFOUND cursor variable in the exit when statement? Why? Level: Intermediate Expected answer: OPEN then FETCH then LOOP followed by the exit when. If they can mention a few of these and describe how they used them. If they include the SQL routines provided by Oracle. DBMS_TRANSACTION. They can be used to hold values for use in later queries or calculations. function and anonymous pl/sql block. or RECORD. non-stored PL/SQL procedures. even better. but not really what was asked. The usual fix involves either use of views or temporary tables so the database is selecting from one while updating the other. What is a mutating table error and how can you get around it? Expected answer: This happens with triggers. 2. 6. DBMS_PIPE. An INNER JOIN will take only matching values from both tables PL/SQL Questions: 1. Describe the difference between a procedure. DBMS_OUTPUT. a function must return a value while a procedure doesn?t have to. Give one method for transferring a table from one schema to another: Level:Intermediate Expected Answer: There are several possible methods. 9. DBA: 1. If it is not specified the tables that already exist will be skipped. INSERT. 3. What is the purpose of the IMPORT option IGNORE? What is it?s default setting? Level: Low Expected Answer: The IMPORT IGNORE option tells import to ignore "already exists" errors. How can you find within a PL/SQL block. The SQLERRM returns the actual error message for the last error encountered. but this only shows errors. or COPY. You have a rollback segment in a version 7. The DBMS_OUTPUT package can be used to show intermediate results from loops and the status of variables as the procedure is executed. store in an error log table. or. What are the types of triggers? Level:Intermediate to high Expected Answer: There are 12 types of triggers in PL/SQL that consist of combinations of the BEFORE. ROW. how can it be restored to optimal? . CREATE TABLE. the error is ignored and the tables data will be inserted.Page 126 of 259 Expected answer: SQLCODE returns the value of the error number for the last error encountered.2 database that has expanded beyond optimal. DELETE and ALL key words: BEFORE ALL ROW INSERT AFTER ALL ROW INSERT BEFORE INSERT AFTER INSERT etc. UPDATE. The default value is N. AS SELECT. 2. export-import. if a cursor is open? Level: Low Expected answer: Use the %ISOPEN cursor status variable. TABLE. These are especially useful for the WHEN OTHERS exception. the error that occurred in the code. AFTER.. How can you generate debugging output from PL/SQL? Level:Intermediate to high Expected answer: Use the DBMS_OUTPUT package. Another possible method is to just use the SHOW ERROR command. If it is specified. 11. They can be used in exception handling to report. The new package UTL_FILE can also be used. 10.. If the DEFAULT and TEMPORARY tablespace clauses are left out of a CREATE USER command what happens? Is this bad or good? Why? Level: Low Expected answer: The user is assigned the SYSTEM tablespace as a default and temporary tablespace. for the enable clause you must specify the USING INDEX and TABLESPACE clause for primary keys. 6. but only as part of the index definition. DBMS_SESSION.SQL series of SQL procedures. 7.. DBMS_DDL. What happens if a tablespace clause is left off of a primary key constraint clause? Level: Low Expected answer: This results in the index that is automatically generated being placed in then users default tablespace. This is bad because it causes user objects and temporary segments to be placed into the SYSTEM tablespace resulting in fragmentation and improper table placement (only data dictionary objects and the system rollback segment should be in SYSTEM). What is the proper method for disabling and re-enabling a primary key constraint? Level: Intermediate Expected answer: You use the ALTER TABLE command for both.. What happens if the constraint name is left out of a constraint clause? Level: Low Expected answer: The Oracle system will use the default name of SYS_Cxxxx where xxxx is a system generated number. DBMS_OUTPUT and DBMS_SNAPSHOT. when the constraint was disabled the index was dropped and the information is gone.Page 127 of 259 Level: Low Expected answer: Use the ALTER TABLESPACE . These can be viewed as extra credit but aren?t part of the answer. 4. 5. What happens if a primary key constraint is disabled and then enabled without fully specifying the index clause? Level: Intermediate Expected answer: The index is created in the user?s default tablespace and all sizing information is lost.. Oracle doesn?t store this information as a part of the constraint definition. DBMS_UTILITY. DBMS_SQL. SHRINK command. Since this will usually be the same tablespace as the table is being created in. However.. this can cause serious performance problems. This is bad since it makes tracking which table the constraint belongs to or what the constraint does harder.SQL or CAT*. 9. The packages used by DBAs may include: DBMS_SHARED_POOL. What are some of the Oracle provided packages that DBAs should be aware of? Level: Intermediate to High Expected answer: Oracle provides a number of packages in the form of the DBMS_ packages owned by the SYS user. They may also try to answer with the UTL*. 8. . can you recover in the event of a failure? Why or why not? Level: High Expected answer: You can?t use hot backup without being in archivelog mode. what is the best way to get sizing data for the production table implementation? Level: Intermediate . A user is getting an ORA-00942 error yet you know you have granted them permission on the table. How can you tell if a database object is invalid? Level: Low Expected answer: By checking the status column of the DBA_. if the system is not capable of asynchronous IO then up to twice the number of disks used by Oracle number of DB writers should be specified by use of the db_writers initialization parameter. (On UNIX) When should more than one DB writer process be used? How many should be used? Level: High Expected answer: If the UNIX system being used is capable of asynchronous IO then only one is required. 12. This can be prevented or mitigated by breaking the transaction into a set of smaller transactions or increasing the size of the rollback segments and their extents.emp. What causes the "snapshot too old" error? How can this be prevented or mitigated? Level: Intermediate Expected answer: This is caused by large or long running transactions that have either wrapped onto their own rollback space or have had another transaction write on part of their rollback space. 13. ALL_ or USER_OBJECTS views. what is the problem? Level: Intermediate Expected answer: You need to verify the developer has direct grants on all tables used in the view. 11. A developer is trying to create a view and the database won?t let him. He has the "DEVELOPER" role which has the "CREATE VIEW" system privilege and SELECT grants on the tables he is using. You are using hot backup without being in archivelog mode. 16. instead of select empid from emp. 14. You can?t create a stored object with grants given through views.emp.) or has a synonym that points to the object (create synonym emp for scott.Page 128 of 259 10. depending upon whether you own or only have permission on the view or are using a DBA account. what else should you check? Level: Low Expected answer: You need to check that the user has specified the full name of the object (select empid from scott. If you have an example table. So no. you couldn?t recover.) 15. You want to include a carriage return/linefeed in your output from a SQL script.nextval FROM dual. How can you find out how many users are currently logged into the database? How can you find their operating system id? Level: high Expected answer: There are several ways. Use of double ampersands tells SQLPLUS to resubstitute the value for each subsequent use of the variable. SQL/ SQLPlus 1. The quick and dirty way is to look at the number of blocks the table is actually using and ratio the number of rows in the table to its number of blocks against the number of expected rows. What is the problem? Level: Intermediate Expected answer: Somehow two values have been inserted into the dual table. To be prompted for a specific variable.3. greater than 0... How can variables be passed to a SQL routine? Level: Low Expected answer: By use of the & symbol. This table is a single row. One is to look at the v$session or v$process views.. How can you determine if an index needs to be dropped and rebuilt? Level: Intermediate Expected answer: Run the ANALYZE INDEX command on the index to validate its structure and then calculate the ratio of LF_BLK_LEN/LF_BLK_LEN+BR_BLK_LEN and if it isn?t near 1. but this only works against a single instance installation. a single ampersand will cause a reprompt for the value unless an ACCEPT statement is used to get the value from the user. 19.0 (i.. single column table that should only have one value in it. A user selects from a sequence and gets back two values. Or if the ratio BR_BLK_LEN/ LF_BLK_LEN+BR_BLK_LEN is nearing 0. Another if you are on UNIX is to do a "ps -ef| grep oracle|wc -l? command. Another way is to check the current_logins parameter in the v$sysstat view. his select is: SELECT pk_seq." . place the ampersanded variable in the code itself: "select * from dba_tables where owner=&owner_name. &2. 17. 2. how can you do this? Level: Intermediate to high . 18.e. For passing in variables the numbers 1-8 can be used (&1.7 or so) then the index should be rebuilt.&8) to pass the values after the command into the SQLPLUS session.Page 129 of 259 Expected answer: The best way is to analyze the table and then use the data provided in the DBA_TABLES view to get the average row length and other pertinent data for the calculation. CASCADE. although it is hard to document and isn?t always portable is to use the return/linefeed as a part of a quoted string. 6. Another method. min(sum_of_cost). What SQLPlus command is used to format output from a select? Level: low Expected answer: This is best done with the COLUMN command. 7. How do you execute a host operating system command from within SQL? Level: Low Expected answer: By use of the exclamation point "!" (in UNIX and some other OS) or the HOST (HO) command. spool off Essentially you are looking to see that they know to include a command (in this case DROP USER. 4.? from dba_users where username not in ("SYS?. what is this called and give an example Level: Intermediate to high Expected answer: This is called dynamic SQL. item_no Level: Intermediate Expected answer: The only column that can be grouped on is the "item_no" column. count(item_no). 8.) and that you need to concatenate using the ?||? the values selected from the database. the rest have aggregate functions associated with them.?SYSTEM?).Page 130 of 259 Expected answer: The best method is to use the CHR() function (CHR(10) is a return/linefeed) and the concatenation function "||".. How can you call a PL/SQL procedure from SQL? Level: Intermediate Expected answer: By use of the EXECUTE (short form EXEC) command. 3. 5. You want to use SQL to build SQL. What special Oracle feature allows you to specify how the cost based system treats a SQL statement? Level: Intermediate to high .sql select ?drop user ?||username||? cascade. An example would be: set lines 90 pages 0 termout off feedback off verify off spool drop_all.. You want to group the following set of select returns. what can you group on? Max(sum_of_cost). emp_no = e. In the situation where multiple columns make up the proposed key. z correspond to the number of rows in each table involved in the join. ALL ROWS. STAR. If they can give some example hints such as FIRST ROWS. 12. the rowid column. The result set of a three table Cartesian product will have x * y * z number of rows where x. Once the trace file is generated you run the tkprof tool against the trace file and then look at the output from the tkprof tool. If you use a min/max function against your rowid and then select against the proposed primary key you can squeeze out the rowids of the duplicate rows pretty quick. For example: select rowid from emp e where e. You want to determine the location of identical rows in a table before attempting to place a unique index on the table. y. 9. This can also be used to generate explain plan output. You use it by first setting timed_statistics to true in the initialization file and then turning on tracing for either the entire database via the sql_trace parameter or for the session using the ALTER SESSION command. . the network manager complains about the traffic involved. USING INDEX. What is a Cartesian product? Level: Low Expected answer: A Cartesian product is the result of an unrestricted join of two or more tables. What is the default ordering of an ORDER BY clause in a SELECT statement? Level: Low Expected answer: Ascending 13. how can you reduce the network traffic? Level: High Expected answer: Push the processing of the remote data to the remote instance by using a view to preselect the information for the join.emp_no). even better.rowid) from emp x where x.Page 131 of 259 Expected answer: The COST based system allows the use of HINTs to control the optimizer path selection. how can this be done? Level: High Expected answer: Oracle tables always have one guaranteed unique column. they must all be used in the where clause. 10. This will result in only the data required for the join being sent across. You are joining a local and a remote table.rowid > (select min(x. 11. What is tkprof and how is it used? Level: Intermediate to high Expected answer: The tkprof tool is a tuning tool used to determine cpu and execution times for SQL statements. . REDO LOG. Is this bad? Why or why not. Level: Intermediate Expected answer: Multiple extents in and of themselves aren?t bad. This option can be shortened to TERM. Explain plans can also be run using tkprof. How do you set up tablespaces during an Oracle installation? Level: Low Expected answer: You should always attempt to use the Oracle Flexible Architecture standard or another partitioning scheme to ensure proper separation of SYSTEM. The PAGESIZE and LINESIZE options can be shortened to PAGES and LINES. The explain_plan table is then queried to see the execution plan of the statement. TEMPORARY and INDEX segments. for example SET PAGESIZE 60 LINESIZE 80 will generate reports that are 60 lines long with a line width of 80 characters. Once the explain plan table exists you run the explain plan command giving as its argument the SQL statement to be explained. How do you generate file output from SQL? Level: Low Expected answer: By use of the SPOOL command Tuning Questions: 1. 18. Setting TERMOUT OFF turns off screen output. A tablespace has a table with 30 extents in it. How do you prevent output from coming to the screen? Level: Low Expected answer: The SET option TERMOUT controls output to the screen. 17. What is explain plan and how is it used? Level: Intermediate to high Expected answer: The EXPLAIN PLAN command is a tool to tune SQL statements.sql script. How do you prevent Oracle from giving you informational messages during and after a SQL statement execution? Level: Low Expected answer: The SET options FEEDBACK and VERIFY can be set to OFF. This is created using the utlxplan. However if you also have chained rows this can hurt performance.Page 132 of 259 14. 2. How do you set the number of lines on a page of output? The width? Level: Low Expected answer: The SET command in SQLPLUS is used to control the number of lines generated per page and the width of those lines. DATA. 15. ROLLBACK. To use it you must have an explain_table generated in the user you are running the explain plan for. 16. . 8. Is this bad or good? If bad -How do you correct it? Level: Intermediate Expected answer: If you get excessive disk sorts this is bad. You can increase copy latches via the initialization parameter LOG_SIMULTANEOUS_COPIES to twice the number of CPUs on your system. When looking at v$sysstat you see that sorts (disk) is high. Once the trace file is generated you run the tkprof tool against the trace file and then look at the output from the tkprof tool. This indicates you need to tune the sort area parameters in the initialization files. The two should have a product equal to 64 or a multiple of 64.Page 133 of 259 3. This can also be used to generate explain plan output. what should you check first? Level: Low Expected answer: Ensure that users don?t have the SYSTEM tablespace as their TEMPORARY or DEFAULT tablespace assignment by checking the DBA_USERS view. When should you increase copy latches? What parameters control copy latches? Level: high Expected answer: When you get excessive contention for the copy latches as shown by the "redo copy" latch hit ratio. You see multiple fragments in the SYSTEM tablespace. What is the general guideline for sizing db_block_size and db_multi_block_read for an application that does many full table scans? Level: High Expected answer: Oracle almost always reads in 64k chunks. getting error ORA-04031. 9. Explain the use of TKPROF? What initialization parameter should be turned on to get full TKPROF output? Level: High Expected answer: The tkprof tool is a tuning tool used to determine cpu and execution times for SQL statements. The major sort are parameter is the SORT_AREA_SIZe parameter. What is the fastest query method for a table? Level: Intermediate Expected answer: Fetch by rowid 7. Another indication is steadily decreasing performance with all other tuning parameters the same. What are some indications that you need to increase the SHARED_POOL_SIZE parameter? Level: Intermediate Expected answer: Poor data dictionary or library cache hit ratios. You use it by first setting timed_statistics to true in the initialization file and then turning on tracing for either the entire database via the sql_trace parameter or for the session using the ALTER SESSION command. 6. 5. 4. If you see contention for library caches how can you fix it? Level: Intermediate Expected answer: Increase the size of the shared pool. Generally speaking an instantaneous reading gives more valuable data since it will tell you what your instance is doing for the time it was generated over. rollback or data blocks.ora file for an indication of manually set parameters. 16. If you do a comparison between pairs of readings based on some arbitrary time span. DATA is data base buffers. this is the instantaneous ratio for that time span. how does it happen? How can you reduce it? How do you correct it? Level: high Expected answer: Row chaining occurs when a VARCHAR2 value is updated and the length of the new value is longer than the old value and won?t fit in the remaining block space. UNDO is rollback segments. 13. 11. look in the v$parameter view. 12. What is the difference between instantaneous and cumulative hit ratio and which should be used for tuning? Level: Intermediate Expected answer: The hit ratio is a measure of how many times the database was able to read a value from the buffers verses how many times it had to re-read a data value from the disks. Where can you get a list of all initialization parameters for your instance? How about an indication if they are default settings or have been changed? Level: Low Expected answer: You can look in the init. If you simply take the ratio of existing parameters this will be a cumulative value since the database started. If you see statistics that deal with "undo" what are they really talking about? Level: Intermediate Expected answer: Rollback segments and associated structures.Page 134 of 259 10. Is this bad? How can you find what is causing it? Level: high Expected answer: Buffer busy waits could indicate contention in redo. It can be corrected by export and import of the effected table. It can be reduced by setting the storage parameters on the table to appropriate values. If a tablespace has a default pctincrease of zero what will this cause (in relationship to the smon process)? . 15. 14. the "class" column tells you with what. their value and whether or not the current value is the default value. Discuss row chaining. For all parameters. The value of the "count" column tells where the problem is. When looking at the estat events report you see that you are getting busy buffer waits. less could indicate problems. Describe hit ratio as it pertains to the database buffers. This results in the row chaining to another block. You need to check the v$waitstat view to see what areas are causing the problem. A value greater than 8090% is good. how do you fix it? Level: Intermediate Expected answer: This indicate that the shared pool may be too small. You see the following on a status report: redo log space requests 23 redo log space wait time 0 Is this something to worry about? What if redo log space wait time is high? How can you fix this? Level: Intermediate Expected answer: Since the wait time is zero.1. How can you tell if a tablespace has excessive fragmentation? Level: Intermediate If a select against the dba_free_space table shows that the count of a tablespaces extents is greater than the count of its data files. 18. If the free space isn?t contiguous then export. If a tablespace shows excessive fragmentation what are some methods to defragment the tablespace? (7. Increase the shared pool size. If you see the value for reloads is high in the estat library cache report is this a matter for concern? Level: Intermediate . If the wait time was high it might indicate a need for more or larger redo logs. 22. then it is fragmented.3 the ?alter tablespace coalesce.8 in the estat library cache report is this a problem? If so.2 and 7. If you see a pin hit ratio of less than 0. drop and import of the tablespace contents may be the only way to reclaim non-contiguous free space. What can cause a high value for recursive calls? How can this be fixed? Level: High Expected answer: A high value for recursive calls is cause by improper cursor usage. In version 7. and or excessive statement re-parses.? is best.? command is the easiest way to defragment contiguous free space fragmentation. 20.3 only) Level: High Expected answer: In Oracle 7. excessive dynamic space management actions. You need to determine the cause and correct it By either relinking applications to hold cursors.2 The use of the 'alter session set events 'immediate trace name coalesce level ts#'. 19.Page 135 of 259 Level: High Expected answer: The SMON process won?t automatically coalesce its free space fragments. use proper space management techniques (proper storage and sizing) or ensure repeat queries are placed in packages for proper reuse. The ts# parameter corresponds to the ts# value found in the ts$ SYS table. no. 21.7.0 to 7. 17. If you see excessive reloads then increase the size of the shared pool. it can even improve performance since Oracle won?t have to create a new extent when a user needs one. You look at the dba_rollback_segs view and see that there is a large number of shrinks and they are of relatively small size. Is there a problem? Should you take any action? Level: Intermediate Expected answer: No there is not a problem. You look at the dba_rollback_segs view and see that you have a large number of wraps is this a problem? Level: High Expected answer: A large number of wraps indicates that your extent size for your rollback segments are probably too small. Is this a problem? Level: Intermediate Expected answer: As long as they are all the same size this isn?t a problem. 26.Page 136 of 259 Expected answer: Yes. You can look at the average transaction size in the same view to get the information on transaction size. Installation/Configuration . Ideally you should have no shrinks or a small number of large shrinks. You see multiple extents in the temporary tablespace.-------------------------R01 11 R02 8 R03 12 R04 9 SYSTEM 4 You have room for each to grow by 20 more extents each. is this a problem? How can it be fixed if it is a problem? Level: High Expected answer: A large number of small shrinks indicates a need to increase the size of the rollback segment extents. To fix this just increase the size of the extents and adjust optimal accordingly. you should strive for zero reloads if possible. In fact. In a system with an average of 40 concurrent users you get the following from a query on rollback extents: ROLLBACK CUR EXTENTS --------------------. Increase the size of your extents to reduce the number of wraps. You have 40 extents showing and an average of 40 concurrent users. 24. 25. Since there is plenty of room to grow no action is needed. 23. As long as they have a logical plan for combining or further separation more or less disks can be specified.ORA 7. It is a method of placing directories and files in an Oracle system so that you get the maximum flexibility for future tuning and file placement.ORA. Be sure enough contiguous disk space is available. What must be installed with ODBC on the client in order for it to work with Oracle? Level: Intermediate Expected answer: SQLNET and PROTOCOL (for example: TCPIP adapter) layers of the transport programs.Page 137 of 259 1. 4. This can fill up your archive log destination causing Oracle to stop to wait for more space. ROLLBACK tablespace on another and still have two for DATA and INDEXES. . They should indicate how they will handle archive logs and exports as well. 5. 2. How do you set up your tablespace on installation? Level: Low Expected answer: The answer here should show an understanding of separation of redo and rollback. TNSNAMES.ORA file 6. TNSNAMES. When configuring SQLNET on the server what files must be set up? Level: Intermediate Expected answer: INITIALIZATION file. data and indexes and isolation os SYSTEM tables from other tables.ORA file. When configuring SQLNET on the client what files need to be set up? Level: Intermediate Expected answer: SQLNET. what should you check first to determine if there is a problem? Level: Intermediate to high Expected Answer: Check to make sure that the archiver isn?t stuck. An example would be to specify that at least 7 disks should be used for an Oracle installation so that you can place SYSTEM tablespace on one. You have been waiting an hour for the initialization script to finish. What should be done prior to installing Oracle (for the OS and the disks)? Level: Low Expected Answer: adjust kernel parameters or OS tuning parameters in accordance with installation guide. You have installed Oracle and you are now setting up the actual instance. Level: Low Expected answer: OFA stands for Optimal Flexible Architecture. redo logs on two (mirrored redo logs) the TEMPORARY tablespace on another. Define OFA. 3. SQLNET. If archive logging is turned on during install a large number of logs will be created. e. Describe third normal form? Level: Low Expected answer: Something like: In third normal form all attributes in an entity are related to the primary key and only to the primary key 2. 9. How many control files should you have? Where should they be located? Level: Low Expected answer: At least 2 on separate disk spindles. Is the following statement true or false: "All relational databases must be in third normal form" Why or why not? . what should you check for? Level: Intermediate Expected answer: The first thing to check with a large SGA is that it isn?t being swapped out. How many disks should you have assuming standard layout for SYSTEM. 12. The redo logs should not be on raw devices on UNIX if it can be avoided. What OS user should be used for the first part of an Oracle installation (on UNIX)? Level: low Expected answer: You must use root first. How many redo logs should you have and how should they be configured for maximum recoverability? Level: Intermediate Expected answer: You should have at least three groups of two redo logs with the two logs each on a separate disk spindle (mirrored by Oracle). Performance is terrible. not just file systems. 13. see disk configuration answer above.Page 138 of 259 8. TEMP and ROLLBACK tablespaces? Expected answer: At least 7. When should the default values for Oracle initialization parameters be used as is? Level: Low Expected answer: Never 11. Data Modeler: 1. You have just started a new instance with a large SGA on a busy existing server. USER. Be sure they say on separate disks. 10. uniform IO and access requirements). You have a simple application with no "hot" tables (i. While 3NF is good for logical design most databases. will not perform well using full 3NF. or the junior janitor because he has no subordinates). 3. UNIX: 1. if they have more than just a few tables. It is used to show the entities and relationships for a database logical model. How should a many-to-many relationship be handled? Level: Intermediate Expected answer: By adding an intersection entity table 7.Page 139 of 259 Level: Intermediate Expected answer: False. 6. Usually some entities will be denormalized in the logical to physical transfer process. Usually it is used when a concatenated key becomes too cumbersome to use as a foreign key. What is an ERD?

Level: Intermediate Expected answer: A derived key comes from a sequence. How can you determine the space left in a file system? Level: Low . neither side is a "may" both are "must") as this can result in it not being possible to put in a top or perhaps a bottom of the table (for example in the EMPLOYEE table you couldn?t put in the PRESIDENT of the company because he has no boss. Why are recursive relationships bad? How do you resolve them? Level: Intermediate A recursive relationship (one where a table relates to itself) is bad when it is a hard relationship (i. 5. 8. These type of relationships are usually resolved by adding a small intersection entity. When should you consider denormalization? Level: Intermediate Expected answer: Whenever performance analysis indicates it would be beneficial to do so without compromising data integrity. 4.e. What does a hard one-to-one relationship mean (one where the relationship on both ends is "must")? Level: Low to intermediate Expected answer: This means the two entities should probably be made into one entity. usually a case-esac or an if-endif or fi structure 7. more. It is stored in both disk and memory and tracts file status. pg 4. There is one inode for each file on the system. . How can you determine the number of SQLNET users logged in to the UNIX system? Level: Intermediate Expected answer: SQLNET users will show up with a process unique name that begins with oracle.Page 140 of 259 Expected answer: There are several commands to do this: du. if you do a ps -ef|grep oracle|wc -l you can get a count of the number of users.

Level: Low Expected answer: rm 5. how can you determine the number of processes that are using this program? Level: intermediate Expected answer: ps -ef|grep *nocomp*|wc -l 9. or bdf 2. What is the purpose of the grep command? Level: Low Expected answer: grep is a string search command that parses the specified string from the specified file or files 8. Some UNIX systems don?t clean up well after themselves. What is redirection and how is it used? Level: Intermediate Expected answer: redirection is the process by which input or output to or from a process is redirected to another process.who -d depending on the system. Most UNIX systems should have a scheduled periodic reboot so file systems can be checked and cleaned and dead or zombie processes cleared out. What is the easiest method to create a file on UNIX? Level: Low Expected answer: Use the touch command 17. What does >> do? Level: Intermediate . 13.or -. The system administrator tells you that the system hasn?t been rebooted in 6 months. How can you find all the processes on your system? Level: Low Expected answer: Use the ps command 14. What is the finger command? Level: Low Expected answer: The finger command uses data in the passwd file to give information on system users. 12. This can be done using the pipe symbol "|". should he be proud of this? Level: High Expected answer: Maybe. How can you find your id on a system? Level: Low Expected answer: Use the "who am i" command.Page 141 of 259 10. This is one of the strengths of UNIX allowing the output from one command to be redirected directly into the input of another command. 11. Inode problems and dead user processes can accumulate causing possible performance and corruption problems. How can you find dead processes? Level: Intermediate Expected answer: ps -ef|grep zombie -. the greater than symbol ">" or the "tee" command. 15. 16. pmon. 18. Review the results from the command to find the command of interest. You can use the command "tcpctl status" to get a full status of the V1 TCPIP server. 4.Page 142 of 259 Expected answer: The ">>" redirection symbol appends the output from the command specified into the file specified. See Servr Msgs & Codes Manual) What could the problem be? Expected answer: The instance name is probably incorrect in their connection string. Users from the PC clients are getting messages indicating : Level: Low ORA-06114: (Cnct err. If you aren?t sure what command does a particular UNIX function what is the best way to determine the command? Expected answer: The UNIX man -k command will search the man pages for the value specified. restart the instance. For SQLNET V2 check for the presence of the LISTENER process(s) or you can issue the command "lsnrctl status". Users from the PC clients are getting the following error stack: Level: Low ERROR: ORA-01034: ORACLE not available ORA-07318: smsget: open error when opening sgadef. How can you determine if an Oracle instance is up from the operating system level? Level: Low Expected answer: There are several base Oracle processes that will be running on multi-user operating systems. The file must already have been created. 2. For example. Any answer that has them using their operating system process showing feature to check for these is acceptable. 5.dbf file. these will be smon. HP-UX Error: 2: No such file or directory What is the probable cause? Expected answer: The Oracle instance is shutdown that they are trying to access. other protocols have similar command formats. What file will give you Oracle instance status information? Where is it located? . 3. dbwr and lgwr. on UNIX a ps -ef|grep dbwr will show what instances are up. Oracle Troubleshooting: 1. How can you determine if the SQLNET process is running for SQLNET V1? How about V2? Level: Low Expected answer: For SQLNET V1 check for the existence of the orasrv process. can't get err txt. If the MAX_DATAFILES is set to low. If pct_increase is zero. you will have to rebuild the control file to increase it before proceeding. You look at your fragmentation report and see that smon hasn?t coalesced any of you tablespaces. even though you know several have large chunks of contiguous free extents. smon will not coalesce their free space. Users aren?t being allowed on the system. You attempt to add a datafile and get: Level: Intermediate ORA-01118: cannot add anymore datafiles: limit of 40 exceeded What is the problem and how can you fix it? Expected answer: When the database was created the db_files parameter in the initialization file was set to 40. until freed What is the problem? Expected answer: The archive destination is probably full. You can shutdown and reset this to a higher value.ora log. Your users get the following error: Level: Intermediate ORA-00055 maximum number of DML locks exceeded What is the problem and how do you fix it? . up to the value of MAX_DATAFILES as specified at database creation. 6. 7.

Choose one of the following queries to identify or remove duplicate rows from a table leaving unique records in the table: Method 1: SQL> DELETE FROM table_name A WHERE ROWID > ( 2 3 SELECT min(rowid) FROM table_name B WHERE A.key_values).key_value1 = t1. . Method 3: (thanks to Kenneth R Vanluvanee) SQL> Delete from my_table where rowid not in( SQL> SQL> select max(rowid) from my_table group by my_column_name ). SELECT 'A ''quoted'' word. This will speed-up th Note 2: If you are comparing NOT-NULL columns.key_values = B. 5. This should not be a problem as all key columns should be NOT NULL. SQL> rename table_name2 to table_name1. Method 2: SQL> create table table_name2 as select distinct * from table_name1. SELECT 'A ''''double quoted'''' word. eliminate N^2 operations (no need to loop through the entire table on each pass by a record).key_value1 and t2. How can I generate primary key values for my table? Create your table with a NOT NULL column (say SEQNO).key_value2 = t1.' FROM DUAL.rowid > t1. 4. Note: If you create an index on the joined fields in the inner loop. for all intents purposes. use the NVL function. Remember that NULL is not equal to NULL. This column can now be populated with unique values: SQL> UPDATE table_name SET seqno = ROWNUM.' FROM DUAL. Method 4: (thanks to Dennis Gurnick) SQL> delete from my_table t1 SQL> where exists (select 'x' from my_table t2 SQL> SQL> SQL> where t2.rowid).key_value2 and t2.

Look at this example: SELECT * FROM (SELECT * FROM my_table ORDER BY col_name_1 DESC) WHERE ROWNUM < 10.0) IN (SELECT ROWID.4) = 0. 13.4) FROM emp). However. Method 2: Use dynamic views (available from Oracle7.ROWNUM. How does one select the TOP N rows from a table? Form Oracle8i one can have an inner-query with an ORDER BY clause. How does one select EVERY Nth row from a table? One can easily select all even. 12. Please note. Use this workaround with prior releases: SELECT * FROM my_table a . However. Please note. there is no explicit row order in a relational database. these queries are quite fun and may even help in the odd situation. construct a query like this: SELECT * FROM tableX WHERE rowid in ( SELECT rowid FROM tableX WHERE rownum <= 7 MINUS SELECT rowid FROM tableX WHERE rownum < 5). MOD(ROWNUM.Page 150 of 259 To display rows 5 to 7.2): SELECT * FROM ( SELECT rownum rn. this query is quite fun and may even help in the odd situation. empno. and concatenate that to the string. The LEVEL pseudo-column is an indication of how deep in the tree one is. One way of working around this is to use PL/SQL... sum(decode(deptno. The "connect by prior" clause is rarely implemented in the other database offerings. EMPNO.sal)) DEPT10. and the select matching records from other tables on a row-by-row basis. Look at this example: select lpad(' '. sum(decode(deptno. LEVEL * 2) || ENAME . sum(decode(deptno. One uses the "start with" clause to specify the start of the tree.maxcol) ORDER BY maxcol DESC.30.Page 151 of 259 WHERE 10 >= (SELECT COUNT(DISTINCT maxcol) FROM my_table b WHERE b. ENAME. Also.. open the driving cursor with the "connect by prior" statement... inserting the results into a temporary table for later retrieval. Trying to do this programmatically is difficult as one has to do the top level query first. The SCOTT/TIGER database schema contains a table EMP with a self-referencing relation (EMPNO and MGR columns). One disadvantage of having a "connect by prior" clause is that you cannot perform a join to other tables. then.. for each of the records open a cursor to look for child nodes. More than one record can match the starting condition. this feature is not often found in other database offerings. Oracle can handle queries with a depth of up to 255 levels. How does one code a matrix report in SQL? Look at this example query with sample output: SELECT * FROM (SELECT job.maxcol >= a. MGR from EMP connect by prior EMPNO = MGR start with MGR is NULL.20. One can produce an indented report by using the level number to substring or lpad() a series of spaces.40. Look at this example: select LEVEL. 15. How does one code a tree-structured query? Tree-structured queries are definitely non-relational (enough to kill Codd and make him roll in his grave). This table is perfect for tesing and demonstrating tree-structured queries as the MGR column contains the employee number of the "current" employee's boss. 14.10.sal)) DEPT30.sal)) DEPT40 FROM scott.emp GROUP BY job) . sum(decode(deptno.sal)) DEPT20.. . 0. It is one of the good things about Oracle. but use it sparingly if portability is required.

How does one implement IF-THEN-ELSE in a select statement? The Oracle decode function acts like a procedural statement inside an SQL statement to return different values or columns based on the values of other columns in the select statement. 'M'. A. decode( abs(a-b). 'a > b'. 'a = b'. Note: The decode function is not ANSI SQL and is rarely implemented in other RDBMS offerings. select a..---------.Page 152 of 259 ORDER BY 1. 'Female'.

Is it better to put code in triggers or procedures? What is the difference? In earlier releases of Oracle it was better to put as much code as possible in procedures rather than triggers. Can one pass an object/table as an argument to a remote procedure? The only way the same object type can be referenced between two databases is via a database link. In more recent releases both triggers and procedures are compiled when created (stored p-code) and one can add as much code as one likes in either procedures or triggers. END.

POSITION(01:11) INTEGER EXTERNAL.dis' APPEND INTO TABLE my_selective_table WHEN (01) <> 'H' and (01) <> 'T' and (30:37) = '19991217' ( region service_key call_b_no ) 60.bad' DISCARDFILE 'mydata. (01) is the first character. deptno POSITION(17:18) CHAR. mgr ) INTO TABLE proj WHEN projno != ' ' ( projno POSITION(25:27) INTEGER EXTERNAL. Can one selectively load only the records that one need? Look at this example.dat' BADFILE 'mydata. (30:37) are characters 30 to 37: LOAD DATA INFILE 'mydata. POSITION(12:29) CHAR POSITION(20:23) INTEGER EXTERNAL . Look at this example: LOAD DATA TRUNCATE INTO TABLE T1 CONSTANT '31'. FILLER columns are used to skip columns/fields in the load file. ename POSITION(6:15) CHAR. Luckily. Can one skip certain columns while loading data? One cannot use POSTION(x:y) with delimited data. empno POSITION(1:4) INTEGER EXTERNAL ) 59.Page 177 of 259 58. SQL*Plus's predecessor was called UFI (User Friendly Interface).sql SET Modify the SQL*Plus environment eg. What are the basic SQL*Plus commands? The following SQL*Plus commands are available: ACCEPT Get input from the user DEFINE Declare a variable (short: DEF) DESCRIBE Lists the attributes of tables and other objects (short: DESC) EDIT Places you in an editor so you can edit a SQL command (short: ED) EXIT or QUIT Disconnect from the database and terminate SQL*Plus GET Retrieves a SQL file and places it into the SQL buffer HOST Issue an operating system command (short: !) LIST Displays the last command executed/ command in the SQL buffer (short: L) PROMPT Display a text string on the screen. UFI was included in the first releases of Oracle.use when SQL*Loader should combine the same number of physical records together to form one logical record.' ( field1. 62. It can be used interactively or driven from scripts. Make sure you have big rollback segments ready when you use a high value for ROWS=.use if a condition indicates that multiple records should be treated as one. its interface was extremely primitive and anything but user friendly. How can get SQL*Loader to COMMIT only at the end of the load file? One cannot. committing can be reduced. SPOOL Send output to a file. by having a '#' character in column 1.lst START Run a SQL script file (short: @) . How does one load multi-line records? One can create one logical record from multiple physical records using one of the following two clauses: • • CONCATENATE: . What is SQL*Plus and where does it come from? SQL*Plus is a command line SQL and PL/SQL language interface and reporting tool that ships with the Oracle Database Client and Server. field2 FILLER. SQL*Plus is frequently used by DBAs and Developers to interact with the Oracle database. Eg. field3 ) 61. 64. Eg prompt Hello World!!! RUN List and Run the command stored in the SQL buffer (short: /) Saves command in the SQL buffer to a file. but by setting the ROWS= parameter to a large value. CONTINUEIF . 63. Eg SHOW ALL.Page 178 of 259 FIELDS TERMINATED BY '. SET PAGESIZE 23 SHOW Show environment settings (short: SHO). Eg "save x" will create a script file called SAVE x. Eg "spool x" will save STDOUT to a file called x. SHO PAGESIZE etc. This is normally used for nested command files. 66. Eg: SQL> SELECT * FROM TAB WHERE TNAME LIKE '%&TABLE_NAME.buf" 65. the last SQL or PL/SQL command will be saved to a file called AFIEDT.Page 179 of 259 65. "&&" is used to create a permanent substitution variable as with the DEFINE command and the OLD_VALUE or NEW_VALUE clauses of a COLUMN statement. The name "Advanced UFI" was never used officially. short for UFI editing buffer.buf".buf" and then to "afiedt.%'. They presumably needed to keep the name short for compatibility with some of the odd operating systems that Oracle supported in those days. When new features were added to UFI. How can one disable SQL*Plus formatting? Issue the following SET commands to disable all SQL*Plus formatting: SET ECHO OFF SET NEWPAGE 0 SET SPACE 0 SET PAGESIZE 0 SET FEEDBACK OFF SET HEADING OFF SET TRIMSPOOL ON .BUF is the SQL*Plus default edit save file. as the name was changed to SQL*Plus before this version was released.buf". it was the initially named Advanced UFI and the filename was changed to "aufiedt. What is the difference between @ and @@? The @ (at symbol) is equivalent to the START command and is used to run SQL*Plus command scripts. Once you have entered a value it will use that value every time the variable is referenced. @@ will start a sqlplus script that is in the same directory as the script that called it (relative to the directory of the current script). You can overwrite the default edit save file name like this: SET EDITFILE "afiedt. 67. or one that is found in you SQLPATH or ORACLE_PATH. the file name was "ufiedt.BUF and opened in the default editor. A single @ symbol runs the script in your current directory. What is AFIEDT. When you issue the command "ed" or "edit" without arguments.BUF? AFIEDT. What is the difference between & and &&? "&" is used to create a temporary substitution variable and will prompt you for a value every time it is referenced. or one specified with a full or relative path. In the prehistoric days when SQL*Plus was called UFI. There are many which developers should be aware of such as DBMS_SQL. UTL_FILE. If they can mention a few of these and describe how they used them. 72.sql var1 var2 var3 Parameter var1 will be mapped to SQL*Plus variable &1. Can one send operating system parameters to SQL*Plus? One can pass operating system variables to sqlplus using this syntax: sqlplus username/password @cmdfile.Page 180 of 259 These settings can also be entered on one line. exit 5. Can one copy tables with LONG columns from one database to another? About the fastest way of copying data between databases and schemas are by using the SQL*Plus COPY statement. even better. - 70. DBMS_TRANSACTION. 69. It occurs because the trigger is trying to update a row it is currently using. If they include the SQL routines provided by Oracle. When is a declare statement needed ? . DBMS_PIPE. DBMS_OUTPUT. IMAGE FROM IMAGES. but not really what was asked. great. Look at this example: COPY FROM SCOTT/[email protected]_DB TO SCOTT/[email protected]_DB CREATE IMAGE_TABLE USING SELECT IMAGE_NO. etc. 71. eg.sql '"test parameter"' dual Where x.sql consists of: select '&1' from &2. DBMS_JOB. or RECORD. They can be used to hold values for use in later queries or calculations. The usual fix involves either use of views or temporary tables so the database is selecting from one while updating the other. DBMS_UTILITY. In Oracle 8 they will be able to be of the %ROWTYPE designation. What packages (if any) has Oracle provided for use by developers? Oracle provides the DBMS_ series of packages. Describe the use of PL/SQL tables Expected answer: PL/SQL tables are scalar arrays that can be referenced by a binary integer. var2 to &2. DBMS_LOCK.: SET ECHO OFF NEWPAGE 0 SPACE 0 PAGESIZE 0 FEED OFF HEAD OFF TRIMSPOOL ON 68. Look at this example: sqlplus scott/tiger @x. DBMS_DDL. 73. DBMS_ALERT. What is a mutating table error and how can you get around it? This happens with triggers. place the ampersanded variable in the code itself: “select * from dba_tables where owner=&owner_name.. 74. 77. 83. what is this called and give an example This is called dynamic SQL. 76. What are the types of triggers? There are 12 types of triggers in PL/SQL that consist of combinations of the BEFORE. What are SQLCODE and SQLERRM and why are they important for PL/SQL developers? SQLCODE returns the value of the error number for the last error encountered. The new package UTL_FILE can also be used.Page 181 of 259 The DECLARE statement is used in PL/SQL anonymous blocks such as with stand alone. UPDATE. 78. 81. You want to use SQL to build SQL.” . &2. How do you execute a host operating system command from within SQL? By use of the exclamation point “!” (in UNIX and some other OS) or the HOST (HO) command. These are especially useful for the WHEN OTHERS exception. TABLE. How can you find within a PL/SQL block. 75. The DBMS_OUTPUT package can be used to show intermediate results from loops and the status of variables as the procedure is executed. You want to include a carriage return/linefeed in your output from a SQL script.. Another method. INSERT.&8) to pass the values after the command into the SQLPLUS session. 82. How can you call a PL/SQL procedure from SQL? By use of the EXECUTE (short form EXEC) command. although it is hard to document and isn’t always portable is to use the return/linefeed as a part of a quoted string.. how can you do this? The best method is to use the CHR() function (CHR(10) is a return/linefeed) and the concatenation function “||”. non-stored PL/SQL procedures. but this only shows errors. a single ampersand will cause a reprompt for the value unless an ACCEPT statement is used to get the value from the user. They can be used in exception handling to report. 80. the error that occurred in the code. Another possible method is to just use the SHOW ERROR command. If not specified in this order will result in the final return being done twice because of the way the %NOTFOUND is handled by PL/SQL. How can variables be passed to a SQL routine? By use of the & symbol. 79. store in an error log table. The SQLERRM returns the actual error message for the last error encountered. How can you generate debugging output from PL/SQL? Use the DBMS_OUTPUT package.. if a cursor is open? Use the %ISOPEN cursor status variable. or. Use of double ampersands tells SQLPLUS to resubstitute the value for each subsequent use of the variable.sql . An example would be: set lines 90 pages 0 termout off feedback off verify off spool drop_all. It must come first in a PL/SQL stand alone file if it is used. AFTER. To be prompted for a specific variable. ROW. In what order should a open/fetch/loop set of commands in a PL/SQL block be implemented if you use the %NOTFOUND cursor variable in the exit when statement? Why? OPEN then FETCH then LOOP followed by the exit when. For passing in variables the numbers 1-8 can be used (&1. DELETE and ALL key words: BEFORE ALL ROW INSERT AFTER ALL ROW INSERT BEFORE INSERT AFTER INSERT etc. What SQLPlus command is used to format output from a select? This is best done with the COLUMN command. 85. the network manager complains about the traffic involved. 89. min(sum_of_cost). The explain_plan table is then queried to see the execution plan of the statement. STAR. how can you reduce the network traffic? Push the processing of the remote data to the remote instance by using a view to pre-select the information for the join. item_no Expected answer: The only column that can be grouped on is the “item_no” column. What is explain plan and how is it used? The EXPLAIN PLAN command is a tool to tune SQL statements..Page 182 of 259 select ‘drop user ‘||username||’ cascade. This is created using the utlxplan. What special Oracle feature allows you to specify how the cost based system treats a SQL statement? The COST based system allows the use of HINTs to control the optimizer path selection. The PAGESIZE and LINESIZE options can be shortened to PAGES and LINES.) and that you need to concatenate using the ‘||’ the values selected from the database. 84. What is the default ordering of an ORDER BY clause in a SELECT statement? Expected answer: Ascending 91.CASCADE.. Once the explain plan table exists you run the explain plan command giving as its argument the SQL statement to be explained. for example SET PAGESIZE 60 LINESIZE 80 will generate reports that are 60 lines long with a line width of 80 characters. You want to group the following set of select returns. If they can give some example hints such as FIRST ROWS. Explain plans can also be run using tkprof. The result set of a three table Cartesian product will have x * y * z number of rows where x. This will result in only the data required for the join being sent across.rowid > (select min(x. 88. y. You want to determine the location of identical rows in a table before attempting to place a unique index on the table. 90. z correspond to the number of rows in each table involved in the join. count(item_no). they must all be used in the where clause.emp_no = e. how can this be done? Oracle tables always have one guaranteed unique column.rowid) from emp x where x. spool off Essentially you are looking to see that they know to include a command (in this case DROP USER. 86. For example: select rowid from emp e where e.’SYSTEM’). the rest have aggregate functions associated with them.sql script. In the situation where multiple columns make up the proposed key. what can you group on? Max(sum_of_cost). 87. What is a Cartesian product? A Cartesian product is the result of an unrestricted join of two or more tables. the rowid column. 92. even better. ALL ROWS. You are joining a local and a remote table. USING INDEX.’ from dba_users where username not in (“SYS’. If you use a min/max function against your rowid and then select against the proposed primary key you can squeeze out the rowids of the duplicate rows pretty quick. .emp_no). How do you set the number of lines on a page of output? The width? The SET command in SQLPLUS is used to control the number of lines generated per page and the width of those lines. To use it you must have an explain_table generated in the user you are running the explain plan for. Pmon Clears and Frees resources that process was using. b) LogWriter (LGWR): LogWriter writes the redo log entries to disk. This option can be shortened to TERM. How do you prevent Oracle from giving you informational messages during and after a SQL statement execution? The SET options FEEDBACK and VERIFY can be set to OFF. This is required since the data is not written whenever a transaction is committed. There are basically 9 Processes but in a general system we need to mention the first five background processes. The various background processes in oracle are a) Data Base Writer (DBWR): Data Base Writer Writes Modified blocks from Database buffer cache to Data Files. c) System Monitor (SMON): The System Monitor performs instance recovery at instance startup. LGWR writes log entries into a online redo log file. e) Checkpoint (CKPT): At Specified times. As transactions commit and log buffer fills. 95. 94. Setting TERMOUT OFF turns off screen output. Redo Log data is generated in redo log buffer of SGA. How do you prevent output from coming to the screen? The SET option TERMOUT controls output to the screen.Page 183 of 259 93. This is useful for recovery from system failure d) Process Monitor (PMON): The Process Monitor performs process recovery when user Process fails. They do the house keeping activities for the Oracle and are common in any system. What are Background processes in Oracle and what are they. How do you generate file output from SQL? Expected answer: By use of the SPOOL command 96. all modified database buffers in SGA are written to data files by DBWR at Checkpoints and Updating all data files and control files of database to indicate the most recent checkpoint f) Archieves (ARCH) :: The Archiver copies online redo log files to archival storal when they are busy. g) Recoveror (RECO) :: The Recoveror is used to resolve the distributed transaction in network h) Dispatcher (Dnnn) :: The Dispatcher is useful in Multi Threaded Architecture i) Lckn :: . f. b.g :: Alter Statements. Oracle uses an implicit cursor statement for Single row query and Uses Explicit cursor for a multi row query.g:: Using the Sql Statements in languages such as 'C'. .Page 184 of 259 We can have upto 10 lock processes for inter instance locking in parallel sql. According to ANSI. c) Transaction Control Statements: Manage change by DML c) Session Control Used to control the properties of current session enabling and disabling roles and changing . Rollback A transaction that retracts any of the changes resulting from SQL statements in Transaction. intermediate markers or savepoints are declared.S in Programming Language. They are a) Data Defination Language(DDL) : The DDL statments define and maintain objects and drop objects. What is a Transaction in Oracle A transaction is a Logical unit of work that compromises one or more SQL Statements executed by a single User. c.e. Committing A transaction is said to be commited when the transaction makes permanent changes resulting from the SQL statements. 99.g:: Alter System e) Embedded Sql Incorporate DDL. Set Role d) System Control Statements Change Properties of Oracle Instance . Cursor A cursor is a handle (name or a pointer) for the memory associated with a specific statement.e. e.e. A cursor is basically an area allocated by Oracle for executing the Sql Statement. a transaction begins with first executable statment and ends when it is explicitly commited or rolled back.C.Fetch. b) Data Manipulation Language(DML) : The DML statments manipulate database data. Key Words Used in Oracle The Key words that are used in Oracle are: a. Rolling Forward :: Process of applying redo log during recovery is called rolling forward. execute and close 98.DML and T. SavePoint For long transactions that contain many SQL statements. System Global Area(SGA) :: d. 97. Open. How many types of Sql Statements are there in Oracle There are basically 6 types of sql statments. Savepoints can be used to divide a transaction into smaller points. g. 102. variables and other Package Contents 101. k. What are Procedure. Procedures do not Return values while Functions return one One Value Packages Packages Provide a method of encapsulating and storing related procedures. c) Business Integrity Rules :: . Process A Process is a 'thread of control' or mechansim in Operating System that executes series of steps. How many Integrity Rules are there and what are they There are Three Integrity Rules. h. What are Database Triggers and Stored Procedures Database Triggers :: Database Triggers are Procedures that are automatically executed as a result of insert in.A total of 6 combinations At statement level(once for the trigger) or row level( for every execution ) 6 * 2 A total of 12. The advantage of using the stored procedures is that many users can use the same procedure in compiled and ready to use format. Program Global Area (PGA) :: The PGA is a memory buffer that contains data and control information for server process. Database triggers have the values old and new to denote the old value in the table before it is deleted and the new indicated the new value that will be used. update . They are basically used for backup when a database crashes. functions and Packages Procedures and functions consist of set of PL/SQL statements that are grouped together as a unit to solve a specific problem or perform set of related tasks.Page 185 of 259 The SGA is a shared memory region allocated by the Oracle that contains Data and control information for one Oracle Instance. or delete from table. j. Database Buffer Cache :: Database Buffer of SGA stores the most recently used blocks of database data.3 Onwards. DT are useful for implementing complex business rules which cannot be enforced using the integrity rules. Redo log Buffer Redo log Buffer of SGA stores all the redo log entries.g. update to. The set of database buffers in an instance is called Database Buffer Cache. i. We can have the trigger as Before trigger or After Trigger and at Statement or Row level. Redo Log Files Redo log files are set of files that protect altered database data in memory that has not been written to Data Files. Thus a total of 12 combinations are there and the restriction of usage of 12 triggers has been lifted from Oracle 7.When there is data in Child Tables the Master tables cannot be deleted. 100. b) Foreign Key Integrity Rule :: The FKIR denotes that the relationship between the foreign key and the primary key has to be enforced. They are as follows :: a) Entity Integrity Rule :: The Entity Integrity Rule enforces that the Primary key cannot be Null. e. Stored Procedures Stored Procedures are Procedures that are stored in Compiled form in the database.It consists of Database Buffer Cache and Redo log Buffer. functions.after 3*2.delete 3 before . operations insert. Rowid from dept where (Deptno > 25) c) Optimize_Sql :: By setting the Optimize_Sql = No. The Detail records are shown when the Master Record are shown. c) Deferred with No Auto Query The operator must navigate to the detail block and explicitly execute a query 105.'1'. b) Deferred with Auto Query Oracle Forms defer fetching the detail records until the operator navigates to the detail block.'2'. 103. 104.Loc. Here the Null is the else statement where null is done . Oracle Forms assigns seperate cursor only for each query SELECT statement. The various Master and Detail Relationship are a) NonIsolated :: The Master cannot be deleted when a child is exisiting b) Isolated :: The Master can be deleted when the child is exisiting c) Cascading :: The child gets deleted when the Master is deleted. What are the Various Master and Detail Relation ships. f45run module = my_firstform userid = scott/tiger optimize_sql = No d) Optimize_Tp :: By setting the Optimize_Tp= No.This slow downs the processing because for evertime the SQL must be parsed whenver they are executed.'First'. When no_data_found. What are the Various Block Coordination Properties The various Block Coordination Properties are a) Immediate Default Setting.Page 186 of 259 The Third Intigrity rule is about the complex business processes which cannot be implemented by the above 2 rules. They are a) System Exceptions e.'Second'Null). How do you use the same lov for 2 columns We can use the same lov for 2 columns by passing the return values in global values and using the global values in the code 109. How many minimum groups are required for a matrix report The minimum number of groups in matrix report are 4 110.OPTIMIZER_HINT. All other SQL statements reuse the cursor. My_exception exception When My_exception then 108. How do u implement the If statement in the Select Statement We can implement the if statement in the select statement by using the Decode statement.g. Oracle Forms assigns a single cursor for all SQL statements.How many types of Exceptions are there There are 2 types of exceptions.g. When too_many_rows b) User Defined Exceptions e.Dname. Select /*+ First_Rows */ Deptno. What is the difference between static and dynamic lov The static lov contains the predetermined values while the dynamic lov contains values that come at run time . 107.'FIRST_ROWS'). What are the Different Optimisation Techniques The Various Optimization techniques are a) Execute Plan :: we can see the plan of the query and change it accordingly based on the indexes b) Optimizer_hint :: set_item_property('DeptBlock'.e. f45run module = my_firstform userid = scott/tiger optimize_Tp = No 106.g select DECODE (EMP_CAT. Data Files. Once the Data file is created the size cannot change. Parameter Files . They store the data for the database. Views are built using the columns from one or more tables. Every data file is associated with only one database. Unique key is also useful for identifying the distinct rows in the table. 115. Oracle does implement the OOPS concepts. a) System Table space :: This data file stores all the tables related to the system and dba tables b) User Table space This data file stores all the user related tables We should have seperate table spaces for storing the tables and indexes so that the access is fast. What is the difference between candidate key. What is concurrency Cuncurrency is allowing simultaneous access of same data by different users. e. Data Files Every Oracle Data Base has one or more physical data files.This lock should not be applied when we do only select from the row. 116.Parameter File. We can categorise the properties by setting the visual attributes and then attach the property classes for the objects. Locks useful for accesing the database are a) Exclusive The exclusive lock is useful for locking the row when an insert. The best example is the Property Classes. Previleges and Grants Privileges are the right to execute a particulare type of SQL statements.Page 187 of 259 111.update or delete is being done. unique key and primary key Candidate keys are the columns in the table that could be the primary keys and the primary key is the key that has been selected to identify the rows.The grant has to be given by the owner of the object. When a database is created two table spaces are created. Right to resource Grants are given to the objects so that the object might be accessed accordingly. What are the OOPS concepts in Oracle. Control Files Table Space :: The table space is useful for storing the data in the database. Right to create. OOPS supports the concepts of objects and classes and we can consider the peroperty classes as classes and the items as objects 113. The Single Table View can be updated but the view with multi table cannot be updated 112. 114. To increase the size of the database to store more data we have to add data file. b) Share lock We can do the table as Share_Lock as many share_locks can be put on the same resource. What are snap shots and views Snapshots are mirror or replicas of tables.g :: Right to Connect. Table Space. What is a 2 Phase Commit Two Phase commit is used in distributed data base systems.g. It contains DML statements or Remote Procedural calls that reference a remote object.redo log files and time stamp. 117. What are the Pct Free and Pct Used Pct Free is used to denote the percentage of the free space that is to be left when creating a table. What is Row Chaining The data of a row in a table may not be able to fit the same data block. data files . Segments Set of Extents allocated for Extents. What are Codd Rules Codd Rules describe the ideal nature of a RDBMS. 120. No RDBMS satisfies all the 12 codd rules and Oracle Satisfies 11 of the 12 rules and is the only Rdbms to satisfy the maximum number of rules. Data Block One Data Block correspond to specific number of physical database space Extent Extent is the number of specific number of contigious data blocks.:: Pctfree 20. eg :: If a row has been deleted then the table is said to be mutating and no operations can be done on the table except select. name and location of dbs. There are three types of Segments Data Segment Non Clustered Table has data segment data of every table is stored in cluster data segment Index Segment Each Index has index segment that stores data Roll Back Segment Temporarily store 'undo' information 118. What are mutating tables When a table is in state of transition it is said to be mutating. Similarly Pct Used is used to denote the percentage of the used space that is to be used when creating a table eg. 123.acme lang Control Files Control files record the physical structure of the data files and redo log files They contain the Db name.s. . 122. Pctused 40 119.:: db_block_buffers = 500 db_name = ORA7 db_domain = u. A parameter file contains the list of instance configuration parameters e. Data for row is stored in a chain of data blocks . What is the difference between deleting and truncating of tables Deleting a table will not remove the rows from the table but entry is there in the database dictionary and it can be retrieved But truncating a table deletes it completely and it cannot be retrieved. a) Prepare Phase :: Global coordinator asks participants to prepare b) Commit Phase :: Commit all participants to coordinator to Prepared. Physical Storage of the Data The finest level of granularity of the data base are the data blocks. There are basically 2 phases in a 2 phase commit. Read only or abort Reply 121. This is useful to maintain the integrity of the database so that all the users see the same values.Page 188 of 259 Parameter file is needed to start an instance. 126. 130. but you cannot insert. what are the data types supported By oracle (INTERNAL)?

What are attributes of cursor? %FOUND . Number. What is pseudo columns ? Name them? A pseudocolumn behaves like a table column. What is Normalisation Normalisation is the process of organising the tables to remove the redundancy. What is the Difference between a post query and a pre query A post query will fire for every row that is fetched but the pre query will fire only once. a) 1 Normal Form A table is said to be in 1st Normal Form when the attributes are atomic b) 2 Normal Form A table is said to be in 2nd Normal Form when all the candidate keys are dependant on the primary key c) 3rd Normal Form A table is said to be third Normal form when it is not dependant transitively 125.

By using in. collections can store instances of an object type and (except for index-by tables) can be attributes of an object type. you can pass collections as parameters. Ans: REF Cursor is like Pointer whereas PL/SQL Table is like ARRAY. ZERO_DIVIDE 153. 156. use it in “<<label name>>” structure 152. 149. Items of type TABLE are either index-by tables (Version 2 PL/SQL tables) or nested tables (which extend the functionality of index-by tables). What is the difference between REF Cursor & PL/SQL Table. However. VALUE_ERROR. INVALID_NUMBER. collections can have only one dimension and must be indexed by integers. What are the types of Variable binding? Ans: Two types of binding Early Binding (at compile time) Late Binding (Runtime) 154. NO_DATA_FOUND. What are the user defined data types ? Ans: 1. Collections work like the arrays found in most third-generation programming languages. Structured Types Object Types Collection Types Varray Nested Tables REFS (To object Types) 155. Also. Items of type VARRAY are varrays (short for variable-size arrays). all of the same type (for example. you can use them to move columns of data into and out of database tables or between client-side applications and stored subprograms. PL/SQL offers two collection types.Page 192 of 259 Function Overloading means we can use the same procedure name more than one time in a package but the no of parameters should be different or their data type should be different. How can we know that proc has passed a value ? Ans: We can check it using “IN” or “OUT” or “INOUT” parameter. 157. the grades for a class of students). What are the exceptions in PL/SQL Block? Ans: CURSOR_ALREADY_OPEN. In addition. . What Is a Collection? A collection is an ordered group of elements. DUP_VAL_ON_INDEX. Can we use label for anonymous PL/SQL block? Ans: Yes. What are the features of OOPS used in PL/SQL ? Ans: Inheritance – Reusability Abstract Datatype Method Overloading 151. You can define collection types in a package. out parameters we can return the values in procedures 150. REF Cursor can pass to a procedure/function as a parameter directly whereas in PL/SQL table one record has to be passed each time. 3. or delete data from Oracle (and other) databases.0/ 6i and 9i FAQ 1. pass varchar2(10). 2. access.5/ 5. END LOOP 4.Last_Record = 'TRUE') THEN Go_Record(OriPos). END IF. . So.Trigger_Record). What is Oracle Forms and what is it used for? Oracle Forms is a 4GL Rapid Application Development (RAD) environment. You can bypass this screen or customise it by displaying your own logon screen. Code example: OriPos := TO_NUMBER(:System. and database to connect to. LOOP -. How does one iterate through items and records in a specified block? One can use NEXT_FIELD to iterate (loop) through items in a specific block and NEXT_RECORD to iterate through records in a block. Forms Builder is used to create applications to enter. Oracle Forms is part of the Oracle Internet Developer Suite (iDS). you have to regenerate them when ever you change the operating system or the Forms version. ELSE Next_Record. Eg: ON-LOGIN declare uname varchar2(10). EXIT.do processing IF (:System.Page 193 of 259 Oracle Forms 4. It was previously called SQL*Forms. Forms can also be deployed across the Web using the Oracle Internet Application Server (iAS) Forms Services. FMB's are not. Can on bypass the Oracle login screen? The first thing that the user sees when using runform is the Oracle logon prompt asking them for their username. First_Record. The Forms Runtime environment is required to execute compiled Forms modules. password. On the other hand. Can an Forms FMX be moved from one operating system to another? FMX files are operating system dependent.0/ 6. change. You can use SET_WINDOW_PROPERTY on the window called FORMS_MDI_WINDOW to resize this MDI (or any other named) window. A statement like CREATE TABLE X (A DATE). What should I do?

MAXIMIZE). pass||'@connect_database').Page 194 of 259 begin uname := 'username'. 7. Examples: set_window_property(FORMS_MDI_WINDOW. end. 7. How does one suppress or customize error messages in Forms? One can either set the message level using the system variable SYSTEM. FORMS_DDL can also be used to create dynamic SQL statements at runtime. DROP and ALTER are not directly supported from Forms because your Forms are not suppose to manipulate the database structure. set_window_property(FORMS_MDI_WINDOW. 9. Forms run inside a Windows Multiple-Document Interface (MDI) window. you can use the FORMS_DDL built-in to execute DDL statements. Just note that FORMS_DDL will force an implicit COMMIT and may de-synchronize the Oracle Forms COMMIT mechanism. . logon(uname. 6. set_window_property('my_window_name'. Can one execute dynamic SQL from Forms? Yes.WINDOW_STATE. Create a TIMER at the point where you want the navigation to occur. 5. MINIMIZE). pass :='password'.

Can one Maximize/ Minimize a Window in Forms? On MS-Windows. Can one issue DDL statements from Forms? DDL (Data Definition Language) commands like CREATE. POSITION. Eg: FORMS_DDL('INSERT INTO X VALUES (' || col_list || ')'). The FORMS_SUCCESS built-in can be used to determine if the last executed built-in was successful. However. use the FORMS_DDL built-in or call the DBMS_SQL database package from Forms. BUSY.5. To display messages immediately. END IF. INSERTION and CROSSHAIR. BUSY). 2.

Use the following properties for these buttons: Enabled: True Navigable: False Mouse Navigate: False Now set the "Canvas Type" in the canvas property palette to "Horizontal Toolbar" and the "Form Horizontal Toolbar Canvas" in the module property palette to your canvas name (C_TOOLBAR in our case). your message may or may not be displayed. Eg: SET_APPLICATION_PROPERTY(CURSOR_STYLE. The following cursor styles are supported: DEFAULT. 11. 14. 10.'). How does one create a custom toolbar? Create a new block. create_timer('TIMER_X'. synchronize. Application menus can be added to your application by creating Menu Modules (*.Page 195 of 259 Eg. 13. NO_REPEAT). use the SYNCHRONIZE build-in: message('. let's name it "TOOLBAR" and a canvas named "C_TOOLBAR" (for ilustration purposes).. 12. How does one compile MS Help files?

Regardless of whether you call the MESSAGE() built-in with ACKNOWLEDGE.MMX). 5. END. Can one change the mouse pointer in Forms? The SET_APPLICATION_PROPERTY build-in in Oracle Forms allow one to change the mouse pointer. NO_ACKNOWLEDGE. This can also be used to execute a query while the user is looking at the results of a previous query. This is because messages are displayed asynchronously..

How does one deploy a Form on the Web? Follow these steps to deploy a Form on the Web: 1. 3.htm.MESSAGE_LEVEL SYSTEM. Some people also refer to it as the Forms and Reports Server.. What Web Servers can be used with the Forms and Reports Services? The Oracle HTTP Server (Apache Web server) is installed with the Forms and Reports Services. any web server that supports CGI (Common Gateway Interfaces) can be used. Re-compile the Form to a FMX Etc. WebForms can be centrally deployed and managed and provides a nice thin client implementation. the 4. Change host_name and port to the server where you HTTP server is running. With Oracle's Forms and Reports Services one can web-enable existing Oracle Developer (Forms and Reports) applications without changing any application code. Referencing an object is similar to copying an object. 3) Is forms 4. Forms and Reports services as previously known as WebForms and WebReports. Use the following command to start and stop the Forms Services: $ORACLE_HOME/6iserver/forms60_server start $ORACLE_HOME/6iserver/forms60_server stop Test if the Forms server is running by navigating to the following URL: http://host_name:port/dev60html/runform. A reference object automatically inherits any changes that have been made to the source object when you open or regenerate the module that contains the reference object. except that the resulting reference object maintains a link to its source object. However.Page 198 of 259 Oracle Forms and Reports Services is a component of the Oracle Internet Application Server (9iAS) that enables programmers to deploy Oracle Forms and Oracle Reports across the Web. but you have to use FORMS_DDL. 1) PROPERTY CLASS . 2. Forms 4. partially. 3. g. e. The key-next is fired as a result of the key action while the post text is fired as a result of the mouse movement. When-mouse-button-pressed. record groups are separate objects that belong to the form module in which they are defined. 6) What are the types of triggers and how the sequence of firing in text item 6) Triggers can be classified as Key Triggers. Property classes also allow you to make global changes to applications quickly. This setting is typically used for password protection. Key-up.Page 199 of 259 Any string expression up to 32K:     a literal an expression or a variable representing the text of a block of dynamically created PL/SQL code a DML statement or a DDL statement Restrictions: The statement you pass to FORMS_DDL may not contain bind variable references in the string.

Post-Text-item. or DATE provided that the total number of columns does not exceed 64K.first_item’) in the Navigational triggers But can use them in the Key-next-item. etc Navigational Triggers: These Triggers are fired as a result of Navigation. The Difference between Key-next and Post-Text is an very important question. property level trigger won't fire. E. Yes . By simply changing the definition of a property class. However. All type of triggers . 9) If you have property class attached to an item and you have same trigger written for the item * Which will fire first? 9) Item level trigger fires. e. We also have event triggers like when –new-form-instance and when-new-block-instance. Record group column names cannot exceed . The sequence of firing in a text item are as follows :: a) pre .g :: Key-next-field. you can change the definition of all objects that inherit properties from that class. Navigational Triggers. Mouse Triggers. 10) What are record groups? * Can record groups created at run-time? 10) A record group is an internal Oracle Forms data structure that has a column/row framework similar to a database table. Key-Down Mouse Triggers: Mouse Triggers are fired as a result of the mouse navigation.text b) when new item c) key-next d) when validate e) post text 7) Can you store pictures in database? How? 7) Yes. 8) What are property classes ? Can property classes have trigger? 8) Property class inheritance is a powerful feature that allows you to quickly define objects that conform to your own interface and functionality standards. We cannot call restricted procedures like go_to(‘my_block. Key next will not fire unless there is a key event. when-mouse-doubleclicked. Triggers at the lowest level are always given the first preference.g : Pre-text-item. LONG. If item level trigger fires. but the values of bind variables can be concatenated into the string before passing the result to FORMS_DDL. unlike database tables. Key Triggers: Key Triggers are fired as a result of Key action. 5) What is SECURE property? 5) Hides characters that the operator types into the text item. A record group can have an unlimited number of columns of type CHAR. The item level trigger fires first and then the block and then the Form level trigger. The PL/SQL variable that is passed as a parameter must be a valid PL/SQL data type. and lengths from the database columns referenced in the SELECT statement. 11) What are ALERT? 11) An ALERT is a modal window that displays a message notifying operator of some application condition. You obtain a return value from a foreign function by assigning the return value to an Oracle Forms variable or item. you define its Structure and row values at design time. 15) What are timers? When. 14) What is FORMS_MDI_WINDOW? 14) Forms run inside the MDI application window. 16) Can object group have a block? 16) Yes. pass the PL/SQL variable as a parameter value in the PL/SQL interface of the foreign function. data types. After assigning an Oracle Forms variable or item value to a PL/SQL variable. TYPES OF RECORD GROUP: Query Record Group A query record group is a record group that has an associated SELECT statement. The columns in a query record group derive their default names. it must also be the appropriate parameter type as defined in the PL/SQL interface. When Mouse Navigate is set to False. Static Record Group A static record group is not associated with a query. Make sure that the Oracle Forms variable or item is the same data type as the return value from the foreign function. 18) What are user-exits? 18) It invokes 3GL programs. Non-query Record Group A non-query record group is a group that does not have an associated query. record groups can be used whenever the functionality offered by a two-dimensional array of multiple data types is desirable. 17) How many types of canvases are there? 17) There are 2 types of canvases called as Content and Stack Canvas. and they remain fixed at runtime. Programmatically. rather. object group can have block as well as program units. 20) What is IAPXTB structure? 20) The entries of Pro*C and user exits and the form which simulate the Pro*c or user_exit are stored in IAPXTB table in d/b. Content canvas is the default and the one that is used mostly for giving the base effect.Page 200 of 259 30 characters. navigation. 19) Can you pass values to-and-fro from foreign function? how? 19) Yes. when-timer-expired does not fire? 15) The When-Timer-Expired trigger can not fire during trigger. Oracle Forms does not perform navigation (and the resulting validation) to move to the item when an operator activates the item with the mouse. . This property is useful for calling a form from another one. but whose structure and values can be modified programmatically at runtime. Oracle Forms performs standard navigation to move the focus to the item when the operator activates the item with the mouse. 12) Can a button have icon and label at the same time? 12) -NO 13) What is mouse navigate property of button? 13) When Mouse Navigate is True (the default). or transaction processing. The records in a query record group are the rows retrieved by the query associated with that record group. It’s like a plate on which we add items and stacked canvas is used for giving 3 dimensional effects. DLL in the \ORAWIN\BIN directory with the new F45XTB. 31) What is OLE automation? 31) OLE automation allows an OLE server application to expose a set of commands and functions that can be invoked from an OLE container application. user exits support DLL on MS-WINDOWS? 22) YES. Key setting unique (default. OLE automation provides a way for an OLE container application to use the features of an OLE server application to manipulate an OLE object from the OLE container environment. 22) Does.DLL. or rename the DLL to F45XTB.INVOKE (object obj_type. 27) What are key-mode and locking mode properties? level? 27) Key Mode: Specifies how oracle forms uniquely identifies rows in the database.

How? 26) Yes.DLL. non . Method Is a method (procedure) of the OLE2 object. 25) What is pre-compiler? 25) It is similar to C pre-compiler directives. For applications that will run against ORACLE. i. use the default setting. list list_type:= 0). Locking mode: Specifies when Oracle Forms should attempt to obtain database locks on rows that correspond to queried records in the form. 23) What is path setting for DLL? 23) Make sure you include the name of the DLL in the FORMS45_USEREXIT variable of the ORACLE. 26) Can you connect to non . a) immediate b) delayed 28) What are savepoint mode and cursor mode properties ? level? 28) Specifies whether Oracle Forms should issue savepoints during a session. . This property is included primarily for applications that will run against non-ORACLE data sources. (FORMS_OLE) 34) What does invoke built-in do? 34) This procedure invokes a method. Parameters: Object Is an OLE2 Automation Object. If you rename the DLL to F45XTB.DLL. replace the existing F45XTB. color. Current Record Attribute is frequently used at the block level to display the current row in a multi-record If you define an item-level Current Record Attribute. 10) What is OLE Activation style property? 10) Specifies the event that will activate the OLE containing item. between VAT and Property Class? imp 2) Named visual attributes define only font. and pattern of the object at runtime. 3) Which trigger related to mouse? 3) When-Mouse-Click When-Mouse-DoubleClick When-Mouse-Down When-Mouse-Enter When-Mouse-Leave When-Mouse-Move When-Mouse-Up 4) What is Current record attribute property? 4) Specifies the named visual attribute used when an item is part of the current record. The form would be generated in unix system by using f45gen my_form. the resulting module hierarchy is known as the call form stack. color. 11) Can u change the mouse pointer? How? 11) Yes. 6) Can u set default font in forms? 6) Yes. You can change the appearance of objects at runtime by changing the named visual attribute programmatically. and any visual attribute properties in the class are ignored. you can display a pre-determined item in a special color when it is part of the current record. 7) Can u have OLE objects in forms? 7) Yes. but you cannot dynamically highlight the current item. 5) Can u change VAT at run time? 5) Yes. and pattern attributes. 9) What r the types of windows (Window style)? 9) Specifies whether the window is a Document window or a Dialog window. property class assignment cannot be changed programmatically. 37) Can u port applications across the platforms? how? 37) Yes we can port applications across platforms.CREATE_ARGLIST function. Consider the form developed in a windows system. Specifies the mouse cursor style. 8) Can u have VBX and OCX controls in forms? 8) Yes. Change windows registry(regedit).Page 202 of 259 List Is the name of an argument list assigned to the OLE2.fmb scott/tiger GUI 1) What is a visual attribute? 1) Visual attributes are the font. . as the input focus changes. color. 36) What is call form stack? 36) When successive forms are loaded via the CALL_FORM procedure. You can programmatically change an object's named visual attribute setting to change the font. and pattern properties that you set for form and menu objects that appear in your application's interface. the named visual attribute settings take precedence. Set form45_font to the desired font. When an object is inheriting from both a property class and a named visual attribute. Use this property to dynamically change the shape of the cursor. 2) Diff. property classes can contain these and any other properties. make sure the frame you are going to move them into is large enough to accept the whole group at once before . if you are reassigning a group of fields. Even though you set the page size in the report properties. but the printer still prints in portrait. This sets the printer orientation. Moving fields around does not change what enclosing object is considered it's parent group. 17) What is Flex 5) Flex is the property of moving the related fields together by setting the flex property on 18) What are the minimum number of groups required for a matrix report 8) The minimum of groups required for a matrix report are 4 7. Now all of the fields on the layout can be repositioned regardless of their original parent items.. for unknown and mysterious reasons. Oracle will usually figure what your intent was and assign the object(s) as a child of that frame. (Cntrl . the user's default printer setup will be used. One note though. The alternative in this case is to highlight the field (or fields). Oracle carefully remembers what repeating frame a field was originally placed in and assigns that as it's parent. 3) Can u run the report with out a parameter form 15) Yes it is possible to run the report without parameter form by setting the PARAM value to Null 4) What is the lock option in reports layout 16) By using the lock option we cannot move the fields in the layout editor outside the frame. and then paste it into the desired frame. but I'm still getting a "frequency below it's group" error. first click on the lock button on the speed button bar. I switched the page size to 11x8. unless you actually like starting from scratch every time!?! 8. try dragging it out of all of them. This is my preferred method of changing a field's parent as it works much more consistently then the unlock/lock method.5. To change a field's parent. cut it (cntrl-x). For anyone who wants a consistent look in their reports I strongly recommend building a similar pair to save yourself an ulcer. Oracle will parse the layout and assumes that any item fully enclosed in a repeating frame is a child object of that frame. reptmp_p and reptmp_l (portrait and landscape). You can also set it to either "Landscape" or "Portrait" to force the printer orientation no matter what the user has set as default. I moved this field into that repeating frame. this method does not work. Oracle starts by setting it to "default" which means that no matter how you set the page size.Z or edit. If you then reference a column further down the line of the query structure it will return that error. but if you drag and drop it there before clicking on any other objects. It should now look like an unlocked padlock. minor details are the ones which are invariably forgotten when you are designing your report and are the reason I created our two report templates. This is useful for maintaining the fields. and then click on something else. This can be confirmed again by trying to drag an object out of it's parent.5 13) How many types of columns are there and what are they 5) Formula columns: For doing mathematical calculations and returning one value Summary Columns: For doing summary calculations such as summations etc. Place holder Columns: These columns are useful for storing the value in a variable 6) Can u have more than one layout in report 14) It is possible to have more than one layout in a report by using the additional layout option in the layout editor. These sorts of picky. Whichever frame will not allow it to escape is it's parent. there is a another variable in the system parameters section under the data model in the object navigator called orientation. If you are not exactly sure which repeating frame a field belongs to. The paste does not initially set it into the right frame.undo will put it back where it came from) Sometimes.Page 203 of 259 Reports 2. When you are satisfied with the repositioning click the lock button again to lock the layout. you have just discovered one of the main reasons why good planning goes a long way. while Anchoring Object is the parent object (unless you have explicitly anchored the object in which case it is the object to which it is anchored). not the current object. Creation order is there for critical to the layout process. A print condition object of Enclosing Object is whichever object encloses the current object (could be the parent or a frame within the parent). you are probably going to have to delete and then recreate the objects within the desired frame. As an example. our object will not print. if the new frame is fully enclosed within the same higher level frame as the field then the two will be considered sibling children of the higher level frame. save yourself some typing by creating the new object in the right frame. they should all stay together. if an instance of that frame spans more than one page then our object will print on the second and every subsequent page that this instance of the repeating frame spans. that Reports bases it's decision on the printed size rather than the field size you define to determine which objects are too large and must be shifted to the next page. Oracle looks at the layout as a sort of layered inheritance model such that anything created on top of and completely inside another object is by definition a child of that object. Now if you try to click on one of the fields you will not be able to as they are fully covered by the new frame. However. These are used to alter an object position in the Reports layer ordering. . The key here is that this is about the pages on which the Print Condition Object appears. Last. likewise Last is the last page on which any part of the Print Condition Object is printed. All. Oracle will assign it as a child of whatever it is in at the time. This means that once an object has popped to the front and had a reassignment of parent. move forwards. All but first. The solution is to put the whole row into a regular frame which is page protected. but not all of it? This is due to the way the scan works when Oracle is parsing the layout. the bolded field could get shifted to the next page due to it's bigger footprint. This means that even if you set two fields top-aligned with the same height and font but one of them is bolded. Once you de-select an object that has just been pasted. If you do the paste and then try to grow the frame to fit. On every instance of that repeating frame which is printed entirely within a single page. you can place the new repeating frame in the correct place and then use the techniques shown above in the "I moved this field but am still getting a frequency error" to reassign the fields into the new frame. At best. This means that placing a repeating frame on top of a field but larger than that field fails the ownership criteria. You use the "send backwards" option to move the frame backwards until all of the fields have popped to the front and are now enclosed in it. Note that you can only move an object back and forth amongst it's siblings. assume we have created a field inside a repeating frame with Print Condition Object set to 'anchoring object'. bring to front. There is also a second choice (which can also be used as a solution to the above). If the object has triggers attached. copying over the trigger code. this condition is re-evaluated for each instance of the frame. You will find the options Send to back. Go ahead and draw the new frame around the fields you want to have placed in it. For objects inside a repeating frame. You cannot set it back below it's parent. How do I do this easily? Well congratulations. you cannot move it back using these tools. Oracle views First as the first page on which any part of the Print Condition Object is printed. and then deleting the old object 9. What exactly does the "Print Condition" do? The print condition type First. nor in front of it's children. 10. move backwards. Now go to the "Arrange" menu. I must put a repeating frame around these fields. If the tops of all the fields in a row are aligned and the fields are all of the same height and font. however. First. you will have to cut and paste again. All but last refer to the frequency with which you want to appear based upon the setting of the print condition object. Oracle reassigns the new repeating frame as each object's parent as they pop to the front. From this point you have two options. and Print Condition Type set to 'All But First'. I suspect. Why does part of a row sometimes get shifted to the next page.Page 204 of 259 you do the cut/paste. If this technique also fails. 11. g. Why they couldn't catch those problems at compile time I have no idea. but the moment you run the report you will get a nasty error and the report will die. bill_period_id etc. I know that this seems like overkill. if you create a varchar user variable and try to reference it as an SQL condition ( e. What you have to do is create a PL/SQL package that contains a variable as well as the functions to read and write to that variable. except that it probably uses the same PL/SQL compiler as Forms which uses that same syntax for the perfectly acceptable function of changing field values. Reports locks down the user parameters until the report is finished. The following example will select the most recent invoice date as the default. is simple. For example. Once the Before Report trigger has fired. this statement is fully parsed before the parameter form is opened. That being said. This is done in the "Initial Value" spot on the variable's properties form. you use this to save and change your variable value. 13. and note that it properly handles exceptions to ensure that the report does not arbitrarily die if this default setting fails. function BeforePForm return boolean is begin select max(bill_period_end_date + 1) into :p_input_date from billing_period where bill_period_end_date <= (select trunc(sysdate) from dual). However. The secret is that the variable must be initialized to a valid SQL condition before the Data Model will accept it. Simply setting the parameter to a given value in the Before Form trigger will select that option as the default value displayed to the user. Oh. Even if you have used a select statement to create a lookup list for the parameter. 12. return (TRUE). there are times when you may wish to allow a user to add any "where" statement they wish. it must return a true or false value. As you can probably guess. assume you have a parameter called p_input_date which is intended to hold an invoice date. you can't. I know you can put a statement into a layout trigger at design time and the compiler will accept it. Only such things as heading objects you want reprinted on multiple pages are normally candidates for fooling around with this setting. there is valid technique to mimic having a user variable which can be changed over the course of the report execution. this technique is a last resort to finding an SQL work around if one exists. Select * from account where :usercondition) you will get an error. such as a date. even though it only chooses between 'first' and 'last'. The usual default is "1 = 1" which simply means all rows meeting whatever other conditions are included in the select statement will pass this condition if the user does not change it in the parameter form. How do I set the initial values of parameters for the parameter form at runtime? This is what the Before Form trigger is primarily used for. How do I change a user parameter at runtime from a layout object trigger? Quite simply. exception when others then :p_input_date := null. . Since variables inside a package are both local to that package and persistent over the duration of the run. but it is the most efficient way of handling an issue that is very rarely encountered. Note also that like all report triggers. 1. How do I create a truly dynamic 'where' condition which the user can input on the parameter form for my select statement? While setting a simple parameter for use in defining the select statement.Page 205 of 259 For most objects you will not have to play with this print condition setting as the default setting is pretty good at determining what pages to print on. A table type node represents a type created by the SQL statement. Static record group A static record group is not associated with a query.

The type is implied by when the record group is created (at design time or at runtime) and by how the group is defined.Page 206 of 259 return true. Record group types There are three types of record groups: query record groups. Non-query record group A non-query record group is a group that does not have an associated query. and SRW.Set_Field_char(0. It does not change the value held in the cursor and so can not be used for evaluating summary totals. You do not specify the record group type explicitly. for the whole set of objects at once.

While this may be useful for some things. there is a highly unpublicized method of doing just that using the SRW. If the subtype is an object type or REF object. you define its structure and row values at design time.

The PostScript file is a set of instructions telling the printer exactly what to print and how to print it. . Receivables uses the following tables to store your invoice information: RA_CUSTOMER_TRX RA_CUSTOMER_TRX_LINES RA_CUST_TRX_LINE_GL_DIST AR_PAYMENT_SCHEDULES 21. Postscript is a universal printer language and any postscript printer is able to interpret your different design instructions. Assume you wish to print "Cc" where "C" is a different font and a larger point size than "c" and is in boldface type (where "c" is not). for example. If you want a landscape bitmapped report. Bitmapped reports are output as PostScript files. The standard is in effect so a report prints as identically as possible from both conventional and postscript printers. Character mode reports generate ASCII output. specify this either in the Reports Designer or in the execution options of your concurrent program. In postscript. This keeps each operating unit's transaction data separate and secure. In ASCII you cannot dynamically change the font and character size. you can make "C" bold and in a different font and point size than "c".” 20. In Oracle Reports Designer. Both or either could also be bold. a print style is still needed to determine the printer driver used. Enter employee records. Bitmap vs. What is the Multi Org and what is it used for? Ans. AR Invoice Tables? Ans. the Post Script file must be generated as landscape. Bitmap Report? Ans. for example. the APPLICATIONS STANDARDS REQUIRE the report to be designed in ONE FONT/ ONE CHARACTER SIZE. Both or either could also be bold. Use the following query to determine if Muli Org is intalled: “select multi_org_flag from fnd_product_groups. character mode. the following are requirements for each employee record: • the employee name is unique • reimbursement address for either Home or Office exists • address lines 1-3 for the home address do not exceed 35 characters • City/State/Country does not exceed 25 characters • Zip Code for the home address does not exceed 20 characters 19. To avoid confusion. "C" must be in the same font and character size as "c". Bitmap vs. Character-Mode Report Design Here is an example to help explain how Oracle Reports are designed and printed in both the bitmap and character-mode environments. create a special print style for bitmapped reports and make that the required style for all bitmapped reports in the Define Concurrent Programs form.Page 249 of 259 Ans. In Oracle Reports Designer. Character-Mode Report Printing These sequences contrast the two printing environments. Multi Org or Multiple Organizations Architecture allows multiple operating units and their relationships to be defined within a single installation of Oracle Applications. When you enter an invoice either through the Transaction window or through the AutoInvoice program. Either your Human Resources department enters employee information in the People window (if HRMS is installed). or the appropriate department enters employee information in the Enter Person window. "C" can be in a different font and point size than "c". This is because you are generating postscript output. 22. When printing bitmapped reports. In ASCII.
