How to create views
Exercises

1. 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.
2. 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.
3. 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.
4. 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).
5. 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).
6. 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.
