I need help.. what am I doing wrong 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 an id of 6. Movie ids are stored in the movie_id column. Calculate the average rating for "Starman". Alias the average as average_rating.

I am putting:

SELECT AVG(rating), movie_id FROM reviews WHERE movie_id = 6;

You forgot the column alias.

The instructions say "Alias the average as average_rating", so after your function you will need the keyword "AS" and then the alias name.

Also, I see you're including movie_id as a select item, but the instructions only talk about showing the average.

For the most accurate answers, always include a link to the course page with your future questions.
