Question

I’m suppose to get the AVG from the count results.

SELECT labelname AS Record_Labels, COUNT(title) AS Number_of_CDs_Released FROM CD
JOIN RecordLabel ON labelname = released_by
GROUP BY labelname;             

I tried doing this: AVG(COUNT(title)), but it didn’t work. Can anyone help me out here?

You can use a nested query to do this:

select avg(Number_of_CDs_Released) from
(SELECT labelname AS Record_Labels, COUNT(title) AS Number_of_CDs_Released FROM CD
JOIN RecordLabel ON labelname = released_by
GROUP BY labelname) nested;
