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

14,028 PointsI believe your issue is at the end of the statement after "REFERENCES". You only need to reference the tablename(column). So, it probably REFERENCES genres(id)

7,562 PointsOK, this is the challenge: Alter the "t_movies" table to add a foreign key called "fk_genre_id" and constrain it to reference the "t_genres" "pk_id". I try almost everything, what i did not try because I can not see, please help
