Database Foundations 7.4 Question 3

Kind of stuck here, think anyone can help me tweak this to the right answer?

This is what I've got so far:

SELECT IFNULL(AVG(score), 0) AS average FROM reviews RIGHT OUTER JOIN movies ON movies.id=reviews.movie_id GROUP BY movie_id HAVING average <= 2;

Thanks

Hi Jeremy,

You're almost there; you're just missing the "display the movie 'title' before the 'average'" part, which would make it:

SELECT movies.title, IFNULL(AVG(score), 0) AS average FROM reviews RIGHT OUTER JOIN movies ON movies.id = reviews.movie_id GROUP BY movie_id HAVING average <= 2;

I was stuck on the exact same thing. Turned out I was using a "." instead of a "," in the AVG function and the error returned wasn't meaningful. Thanks!
