Quiz question one error.

The question is:

Create a genres table called "t_genres" with an auto incrementing primary key called "pk_id" and a unique column called "uk_name" that can't be null. The "uk_name" is a varchar of up to 45 characters.

My answer:

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

Result:

2d113428-8d09-4c22-ac2d-44f2574a0948.rb:38:in eval': wrong number of arguments (0 for 1+) (ArgumentError) from (eval):11:in ' from 2d113428-8d09-4c22-ac2d-44f2574a0948.rb:38:in eval' from 2d113428-8d09-4c22-ac2d-44f2574a0948.rb:38:in

I can't figure the mistake :( please help.
