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.

The rows in this view should be sorted by the last_name and then first_name columns.

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.

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.
