MySQL right join with count not working properly - mysql

Question

I have the following tables:
MOVIES
+-------------+-------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------------+-------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| user_id | int(11) | YES | MUL | NULL | |
| title | varchar(40) | NO | | NULL | |
| description | text | NO | | NULL | |
| created_at | datetime | YES | | NULL | |
| updated_at | datetime | YES | | NULL | |
+-------------+-------------+------+-----+---------+----------------+
MOVIE_VOTES
+------------+------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+------------+------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| user_id | int(11) | YES | MUL | NULL | |
| movie_id | int(11) | YES | MUL | NULL | |
| like | tinyint(1) | YES | | NULL | |
| created_at | datetime | YES | | NULL | |
| updated_at | datetime | YES | | NULL | |
+------------+------------+------+-----+---------+----------------+
And I want to query all the movies sorted by the number of likes they have. I have this query:
SELECT *, COUNT(*) AS count_likes
FROM movie_votes
RIGHT JOIN movies
ON movies.id=movie_votes.movie_id
WHERE movie_votes.like = 1
GROUP BY movie_id
ORDER BY count_likes;
And this returning the movies sorted by the number of likes BUT not the movies that haven't be voted(liked) yet. For some reason the RIGHT join works as simple join.
I have searched for some relative answers but cant find anything helpful.

Answer 1

You should specify a column name when doing outer joins so that it will count only the non-null values
SELECT movies.id,
movies.user_id,
movies.title,
movies.description,
movies.created_at,
movies.updated_at,
COUNT(movie_votes.movie_id) AS count_likes
FROM movies
LEFT JOIN movie_votes
ON movies.id = movie_votes.movie_id
AND movie_votes.like = 1
GROUP BY movies.id,
movies.user_id,
movies.title,
movies.description,
movies.created_at,
movies.updated_at
ORDER BY count_likes
The condition movie_votes.like = 1 should be put in the ON clause so it will filter the rows in table movie_votes first before joining it to table movies.
