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.

Thanks in Advance!

CREATE TABLE T_GENRES(
pk_id int(3) auto_increment primary key,
uk_name varchar(45) not null
);

Note that primary keys by default are not null, if you want to add anything to a column, you must do it after the datatype declaration
