Joining Tables and Aliasing #2 - LEFT OUTER JOIN
Quick question for the code challenge on Joining Relational Data Between Tables in SQL. Any suggestions would be appreciated.
Q: Like before, bring back the movie 'title' and genre 'name' but use the correct OUTER JOIN to bring back all movies, regardless of whether the 'genre_id' is set or not.
My command: SELECT movie.title AS movie_title, genre.name AS genre_name FROM movies LEFT OUTER JOIN genre_id ON movie.genre_id WHERE name IS NOT NULL;

When you use a join you need 2 tables Example SELECT table1.field1, table1.field2, table2.field1 FROM table1 LEFT OUTER JOIN table2 ON table1.field_id=table2.field2 WHERE "your condition"

select movies.title, genres.name FROM movies LEFT OUTER JOIN genres ON movies.genre_id = genres.id;
