Outer Join not working! I put the following to run my query and I'm confused as to why it's not working.

Here is my code:

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

Many thanks!

Are you using MySQL? Try "RIGHT JOIN" instead of "RIGHT OUTER JOIN"

I am! I just did the change you suggests and it's still not working. Any other ideas? Thanks for your help!

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

cause you are using reviews.id it should be reviews.movie_id
