Hey Artan!

You're right - in the video, the query written is incorrect. From what I understand, she's joining on "media_id" in the video, when it should be joining on "genre_id".

Try this SELECT statement and it should work!

  "SELECT title, category, img, format, year, 
      publisher, isbn, genre
      FROM Media
      JOIN Genres ON Media.genre_id=Genres.genre_id
      LEFT OUTER JOIN Books 
      ON Media.media_id = Books.media_id
      WHERE Media.media_id = $id"

Hope that works for you!

Hey Alex,

Thanks a lot for your answer. This had me stumped for a bit. The course video should be recorded.
