Madeleine Sangoi#300851594 Assignment#3 ______________________________________________________________________________________________ The bb_department table lists the two main business areas in the company (coffee sales and equipment sales); bb_product table contains information on all products, such as name, description, price, sales pricing, etc. Three tables are used to manage product options. Table bb_productoptioncategory records main categories for products (i.e., size and form); table bb_productoptiondetails stores the choices in each category, e.g., whole bean or ground for form; and table bb_productoption links each product to its applicable options. Each product can be associated with many options. Table bb_shopper is to store customers’ information. When a customer begins shopping, a new basket is created in the bb_basket. As the shopper selects items, the selected items are inserted in the bb_basketitem table. Table bb_basketstatus stores data related to order status. Possible statuses include order placed, order verified, and sent to shipping, order shipped, order cancelled, order on back-order. The other tables associated with completing an order include bb_tax and bb_shipping. The company currently calculates shipping cost based on the quantity of items ordered. Q1.

Implement a PL/SQL block to determine whether a customer is rated high, mid or low based on his or her total purchase. If the total purchases are greater than $200, then the customer rated to be high, mid if greater than $100, and low if $100 or lower[5 marks] DECLARE lv_rate bb_basket.total%TYPE; lv_shopper_num bb_basket.idshopper%TYPE; BEGIN SELECT IDSHOPPER, TOTAL INTO lv_shopper_num, lv_rate FROM bb_Basket; IF lv_rate > 200 THEN DBMS_OUTPUT.PUT_LINE('Rate is hight'); ELSE IF lv_rate > 100 THEN DBMS_OUTPUT.PUT_LINE('Rate is MEDIUM'); ELSE IF lv_rate < 100 THEN DBMS_OUTPUT.PUT_LINE('Rate is LOW'); ELSE DBMS_OUTPUT.PUT_LINE('Rate is not Valid'); END IF; END; Q6.
