what's wrong with my SQL?

Challenge Task 1 of 1

We will be writing ONLY the SQL query for this challenge. The library database contains a Media table with the columns media_id, title, img, format, year and category. It also contains a Genres table with the columns genre_id and genre. To join these tables, there is a Media_Genres table that contains the column media_id and genre_id Add to the following SELECT statement to JOIN the Media table and the Genres table using the joining table Media_Genres. SELECT * FROM Media WHERE media_id=3; NOTE: You will need to add the table to the WHERE clause so that the media_id column is not ambiguous.

My sql: SELECT * from media AS m JOIN Media_Genres AS MG ON m.media_id = MG.media_id JOIN genres AS g ON MG.genre_id = g.genre_id WHERE m.media_id=3;

I cannot past this test, can anyone help me with my sql code? Thanks!

Your code seems technically correct.

But I don't think this challenge wants you to use table aliases, try it without them:

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