I am working on joining relational data and I can't get the answer to this question.

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.

So far, I have:

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

can anyone help?

Do you not need the type first?

uk_name VARCHAR(45)

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