How to create views
Exercises
- Create a view named customer_addresses that shows the shipping and billing
addresses for each customer.
This view should return these columns from the Customers table: customer_id,
email_address, last_name and first_name.
This view should return these columns from the Addresses table: bill_line1,
bill_line2, bill_city, bill_state, bill_zip, ship_line1, ship_line2, ship_city, ship_state,
and ship_zip. - Write a SELECT statement that returns these columns from the customer_addresses
view that you created in exercise 1: customer_id, last_name, first_name, bill_line1.
The rows in the result should be sorted by the last_name and then first_name
columns. - Write an UPDATE statement that updates the Customers table using the
customer_addresses view you created in exercise 1. Set the first line of the shipping
address to “1990 Westwood Blvd.” for the customer with an ID of 8. - 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). - 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). - 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.
