4,003 PointsCODE CHALLENGE QUESTION: Grouping, Joining and Cleaning Up Question #3
For some reason, the code challenge isn't accepting my answer even though my results seem to fulfill the question. Any help would be highly appreciated... The specific question is: Challenge task of 3 Like before, group by "movie_id" on reviews, select average "score" as "average", filter out averages over 2 and do an outer join on the movies table. Bring back the movie "title" first then the average. Clean up the average and set it to 0 if null. My proposed answer is: SELECT title, AVG(score) AS average, 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; Checking your answer...
