Confusing PHP/SQL question

Here is the question: 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.

I have no clue what to do, honestly... the JOIN concept wasn't explained much in previous video.

Hi Matthew,

For more info about JOINS I highly suggest you visit https://www.w3schools.com/sql/sql_join.asp

However what you could do is try to INNER JOIN the tables

SELECT * 
FROM Media
INNER JOIN genre ON Media.media_id = genre.media_id;

Or something like that. Feel free to correct me if I am wrong
