Need a little help! What am I missing here?

We're in a movie database. There's a reviews table with the columns of id, movie_id, username, review and rating.

The movie "Starman" has the id of 6. Movie ids are found in the movie_id column in the reviews table. Write a query that totals up all ratings for the movie "Starman" in the reviews table. Alias it as starman_total_ratings.

Type in your command below, then press Ctrl-Enter.

Bummer: Your query didn't perform the correct sum calculation.

SELECT SUM(rating) AS starman_total_ratings FROM reviews WHERE rating = "%Starman%";

You can't use wildcards (%) with an equality test, they only work with the "LIKE" test. But that's not really what you want to be looking for here.

The challenge gave you a hint for building your WHERE clause when it said, "The movie "Starman" has the id of 6."
