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 in the reviews table. Alias it as starman_total_ratings.

SELECT SUM(rating) AS starman_total_ratings FROM reviews WHERE movie_id = 6;
