shortest SQL query for this?

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.

Did you mean to post this in the Databases category? If you use the "get help" button, it should place your post in the right category and include your code and a link to the challenge automatically.

And be sure to make your best "good faith" attempt at writing the code first.

Oh, and here's a hint: you'll need two joins for this one.
