STUCK: Keys and Auto-Incrementing Values Code Challenge (Database foundations: Stage 6)...pt 3

Stuck on this question:

Alter the "t_movies" table to add a foreign key called "fk_genre_id" and constrain it to reference the "t_genres" "pk_id". Type in your command below, then press Enter.

Here is my current entry: ALTER TABLE t_movies ADD COLUMN fk_genre_id, ADD CONSTRAINT FOREIGN KEY(fk_genre_id) References(t_genres)(pk_id);

I believe there is something wrong when I am trying to constrain it ......

Hi James,

I think this is what you're looking for.

Jeff

ALTER TABLE t_movies ADD COLUMN fk_genre_id INTEGER NULL,
ADD CONSTRAINT FOREIGN KEY (fk_genre_id) REFERENCES t_genres (pk_id);
