Question

SELECT username, (SUM(rating)/count(*)) as TheAverage, count(*) as TheCount 
FROM ratings 
WHERE month ='Aug' AND TheCount > 1 
GROUP BY username 
ORDER BY TheAverage DESC, TheCount DESC

I know that’s really close (I think) but it’s saying ‘TheCount’ doesn’t exist in the WHERE clause and the ORDER clause.

The table is:

id, username, rating, month

And I’m trying to work out the average rating for each user then order the results by average rating and number of ratings.

If you group and count, you need having:

SELECT username, (SUM(rating)/COUNT(*)) as TheAverage, Count(*) as TheCount
    FROM rating
    WHERE month='Aug'
    GROUP BY username
    HAVING TheCount > 1
    ORDER BY TheAverage DESC, TheCount DESC
