1. Create a view named order_item_products that returns columns from the Orders, Order_Items, and Products tables.

This view should return these columns from the Orders table: order_id, order_date, tax_amount, and ship_date.

This view should return the product_name column from the Products table.

This view should return these columns from the Order_Items table: item_price, discount_amount, final_price (the discount amount subtracted from the item price), quantity, and item_total (the calculated total for the item).

2. Create a view named product_summary that uses the view you created in exercise 4. This view should return summary information about each product.

Each row should include product_name, order_count (the number of times the product has been ordered) and order_total (the total sales for the product).

3. Write a SELECT statement that uses the view that you created in exercise 5 to get total sales for the five best selling products. Sort the result set by the order_total column in descending sequence.

Chapter 13

The script that you create in the following exercises should use the same general structure as the script presented in Figure 13-1 in the book.

Write a script that creates and calls a stored procedure named test. This stored procedure should declare a variable and set it to the count of all products in the Products table. If the count is greater than or equal to 7, the stored procedure should display a message that says, The number of products is greater than or equal to 7. Otherwise, it should say, The number of products is less than 7.
