Task 1

We have a 'movies' table with a 'title' and 'genre_id' column and a 'genres' table has an 'id' and 'name' column. Use an INNER JOIN to join the 'movies' and 'genres' tables together only selecting the movie 'title' first and the genre 'name' second.


Wow, right? What does all that mean? Basically we need to SELECT specific columns (movies.title and genres.name) FROM a table (movies) and INNER JOIN them to another table (genres) ON specific id matching a value (movies.genre_id and genres.id).

SELECT movies.title, genres.name FROM movies INNER JOIN genres ON movies.genre_id = genres.id;

Does that make any sense? Post back if you are still stuck or have further questions.

Happy coding,
