Courses Plus Student 14,477 Pointscode challenge won't accept my mysql code
the code challenge on the keys and auto-increment won't accept: create table t_genres( pk_id integer auto_increment primary key, uk_name unique key varchar(55));
It continues to say I didn't do the pd_id right.

CREATE TABLE t_genres ( pk_id INTEGER NOT NULL AUTO_INCREMENT PRIMARY KEY , uk_name VARCHAR(45) NOT NULL UNIQUE KEY);

Courses Plus Student 14,477 PointsThanks Geoffrey. I'll try that.

28,736 PointsYep, no worries, I verified in the meantime and that works as it should.

Courses Plus Student 14,477 Pointsgeoffrey that worked. Wish they would have told you to put not null. Especially after they told us that it wasn't necessary for a primary key. Still a great tutorial.

28,736 PointsYes, you are right about that, I honestly went through this tutorial some months ago, but I remember I had the same thought. Anyway, as far as we know It's not necessary to add it... that's the matter. I guess they specify to use it in the exercise to be sure we know how to use it. But, that would have been better to ask us to provide that for the uk_name column. In fact I've just figured out I specified as well NOT NULL for this column, but this isn't needed to pass the exercise. Keep it up, that course gave a me good basic knowledge of SQL for my little PHP projects.
