I have these 3 queries:
SELECT
title, year, MovieGenres(m.mid) genres,
MovieDirectors(m.mid) directors, MovieWriters(m.mid) writers,
synopsis, poster_url
FROM movies m
WHERE m.mid = 1;
SELECT AVG(rating) FROM movie_ratings WHERE mid = 1;
SELECT COUNT(rating) FROM movie_ratings WHERE mid = 1;
And I need to join them into a single query. I was able to do it like this:
SELECT
title, year, MovieGenres(m.mid) genres,
MovieDirectors(m.mid) directors, MovieWriters(m.mid) writers,
synopsis, poster_url, AVG(rating) average, COUNT(rating) count
FROM movies m INNER JOIN movie_ratings mr
ON m.mid = mr.mid
WHERE m.mid = 1
GROUP BY
title, year, MovieGenres(m.mid), MovieDirectors(m.mid),
MovieWriters(m.mid), synopsis, poster_url;
But I don't really like that "huge" GROUP BY, is there a simpler way to do it?
