Add to the following SELECT statement to JOIN the Media table and the Genres table using the joining table Media_Genres.

I can't figure out what I am doing wrong? Can someone help?

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

Here a few hints:

  • a WHERE clause would come after any JOIN clauses
  • the requirements don't sound like a WHERE is needed anyway
  • the first thing after the JOIN keyword should be a table name
  • since the instructions indicate a junction table is needed, there will be 2 JOINs

In future questions, please provide a link to the course page to facilitate an accurate answer.

The basic syntax is: "JOIN table_name ON key_matching_expression". You have all these parts in your code above, but they got mixed with a WHERE clause. As I mentioned before, this challenge will require 2 joins because there are 3 tables.
