Hi. I'm at 4 minutes 14 seconds in the video. I've tried to run the syntax below but got an error:
SELECT title, MIN(score) AS minimum_score,
MAX(score) AS maximum_score,
IFNULL(AVG(score).0) AS average
FROM movies LEFT OUTER JOIN reviews
ON movies.id = reviews.movie_id
GROUP BY movie_id;
As far as I'm aware, this is the same as Andrew's, so I don't understand why it works for him but not for me.
I'd appreciate any help.

IFNULL(AVG(score), 0)

33,236 Points@Corey: Hi Corey. Thanks for clarifying this and sorry for the delay. When I looked at the video, it looked like a dot especially as I couldn't see a space between it and the 0. It was so small.
I would up vote your answer and give you Best Answer but neither option shows up here. Thank you. :-)
