Databases

Need help on this SQL error?

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.

Sorry, I had a typo. It should have been this:

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

Please give a link to the Challenge so we can test our suggestion before sending it back. Without it we don't even know which of the Database courses you are in.

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

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

The error was on starman_total_ratings which you put asstart man_total_ratings

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

SELECT SUM(rating) AS start_man_total_ratings FROM reviews GROUP BY movie_id HAVING movie_id=6;
