I have a table called PGRating.  I want to be able to add the values in the Rating column all together and then take an average of that.  in plain english, here is the formula:

select (Sum of all Rating values) / (count of rows)
from PGRating
where PGImageID = @PGImageID

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
