Database Foundations: Grouping, Joining and Cleaning Up
So the question is: Like before, select the average "score" as "average", setting to 0 if null, by grouping the "movie_id" from the "reviews" table. Also, do an outer join on the "movies" table with it's "id" column and display the movie "title" before the "average". Finally filter out any "average" score over 2.
and what I've got so far is: select ifnull(avg(score), 0) as average from reviews outer join movies on movies.id = movies.title group by movies having average < 2
Im getting the error: Youre missing the HAVING keyword. But Im definitely not Can anyone help?

Your join seems incorrect. I am assuming the id field is a bunch of ints and the movies.title is some type of varchar. If you join table movies and reviews look for that one column in both tables that is common. If possible, improve the way you display your code.
