Open the Aggregating Artists.sql file from the folder shown above. You'll find a query which counts the singles released by each artist.
Some of the results you should see if you run the query.
Use the existing query as a derived table and join it to the Artist table so that you can display the name of the artist rather than just the ID.
The results are a little more readable now.
Add more derived table subqueries and join them to the Artist table to see the results shown below:
Take care with the type of join that you use!
Save and close the file.
