You are trying to JOIN Media_Genres two times in your code. Try just Genres on the second JOIN.

SELECT  *  FROM  Media   JOIN  Media_Genres ON Media.media_id = Media_Genres.media_id  JOIN Genres ON  Genres.genre_id = Media_Genres.genre_id  WHERE Media.media_id=3;

'Genres.genre_id = Media_Genres.genre_id' Here you are not join the 'Generes' table, but you are using, make it correct the table name in second join, then it will work, SELECT * FROM Media JOIN Media_Genres ON Media.media_id = Media_Genres.media_id JOIN Media_Genres ON Genres.genre_id = Media_Genres.genre_id WHERE Media.media_id=3;
