update

Hi,

I have two tables like of this structure

content (content_id, content_type, user_id, time, comment_count)

comments (comment_id, content_id, userid, comment, comment_time)

What I wold like to do is update the comments_count field with sum of comments i.e COUNT(content_id) from the comments table.

I am not able to figure out the right syntax

Thanks
