Before you can do this exercise, you'll need to download and unzip this file .

If you don't have copy of the Music_01 database, follow the instructions at the following link to create it: www.wiseowl.co.uk/sql/exercises/standard/using-sql-server/5257/

Open the Temp Chart Toppers.sql file. You'll find two queries which return the albums and singles which reached number 1 in the charts.

Use a CREATE TABLE statement to create a temporary table called #ChartToppers with columns as shown below:

Column name	Data type
Title	nvarchar(255)
Artist	nvarchar(255)
Release_date	date
US_sales_(m)	float
Release_type	nvarchar(6)

If you want to test the script multiple times, you might find it useful to add a statement to drop the temporary table if it exists before creating it.

Use INSERT statements to store the results of the two queries in the temporary table.

Write a query to select everything from the temporary table, sorting the results by the Release_date.
