Question about the Statement.

At about one minute into the Joining Table and Aliasing video he add's "= genres.id;" on the end of the statement but fails to explain why. Can someone please explain that portion for me. I might be forgetting something we already covered and if thats the case I will go back and re-watch that section.

Thanks in advance.

'movies.genre_id' stands for the 'genre_id' column in the 'movies' table.

He's joining that column with the 'id' column in the 'genres' table.

So he's joining "movies.genre_id" with "genres.id" :)
