Create a query to select the columns shown in the image below from the Album table. Sort the results in descending order of US sales.
If you're curious about who made the top selling album you could copy the Wiki URL into a web browser.
Modify the query so that it returns only the top five best-selling albums. You can use the SELECT TOP n syntax to specify the number of rows you want to return.
These are the results you should see.
The fifth album in the list sold 18 million copies. At the moment we can't see if any other albums have the same sales figures. Modify the query so that it returns any additional albums whose sales are tied with the fifth one. You can use the WITH TIES syntax to do this.
You should return one more row than the five you've requested.
In the same script, write a new query to return the three most recently released albums. Make sure to include any additional albums that were released on the same date as the third one.
You should return more than the three results you request.
Write another query in the same script which shows the ten longest albums. The image below shows the last few rows you should return:
You'll need to sort by two columns to get the results in the correct order.
Create another query in the same script to show the ten shortest albums.
The first few results you should see.
Save the query as The Long and Short of it.sql and close it down.
