How to retrieve data  from two or more tables

Exercises

  1. Write a SELECT statement that joins the Categories table to the Products table and returns these columns: category_name, product_name, list_price.

Sort the result set by the category_name column and then by the product_name column in ascending sequence. (10 rows)

  1. Write a SELECT statement that joins the Customers table to the Addresses table and returns these columns: first_name, last_name, line1, city, state, zip_code.

Return one row for each address for the customer with an email address of allan.sherwood@yahoo.com. (2 rows)

  1. Write a SELECT statement that joins the Customers table to the Addresses table and returns these columns: first_name, last_name, line1, city, state, zip_code.

Return one row for each customer, but only return addresses that are the shipping address for a customer. Hint: join on customer_id AND shipping_address_id equal to address_id. (8 rows)

  1. Write a SELECT statement that joins the Customers, Orders, Order_Items, and Products tables. This statement should return these columns: last_name, first_name, order_date, product_name, item_price, discount_amount, and quantity.

Use aliases for the tables.

Sort the final result set by the last_name, order_date, and product_name columns.

(12 rows)

  1. Write a SELECT statement that returns the product_name and list_price columns from the Products table.

Return one row for each product that has the same list price as another product.
Hint: Use a self-join to check that the product_id columns aren’t equal but the list_price columns are equal.

Sort the result set by the product_name column. (2 rows)

  1. Write a SELECT statement that returns these two columns:

category_name       The category_name column from the Categories table

product_id             The product_id column from the Products table

Return one row for each category that has never been used. Hint: Use an outer join and only return rows where the product_id column contains a null value. (1 row)

 

  1. Use the UNION operator to generate a result set consisting of three columns from the Orders table:

ship_status             A calculated column that contains a value of SHIPPED or NOT SHIPPED

order_id                 The order_id column

order_date              The order_date column

If the order has a value in the ship_date column, the ship_status column should contain a value of SHIPPED. Otherwise, it should contain a value of NOT SHIPPED.

Sort the final result set by the order_date column. (9 rows)
