I am wanting to count the number of users (rows) who have messages.
users - table
message_count - shows how many messages
I am selecting user.message_count without any problem.
SELECT xf_user.message_count,
I then have
SUM(CASE WHEN user.message_count > 0 THEN 1 ELSE 0 END) AS usersWithMessages,
However I'm not getting anything for usersWithMessages
Any advice?
