Select count(distinct user_id) From orders -----Original Message----- From: Ben Nadel [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 11, 2006 2:51 PM To: CF-Talk Subject: Distinct value count (SQL) So, I have to do queries occassionally where I have to get the count of unique items in a query. I don't want to return the items, I just want to count them. I end up doing something like: -----------------------------+ SELECT COUNT(*) AS user_count FROM ( SELECT DISTINCT o.user_id FROM orders o ) AS t1 -----------------------------+ I always hate doing it this way as it seems like an extra step that there must be a way to avoid. And, I know zero about how SQL works behind the scenes, but this just seems like it would need to create some temp table, which may or may not be the best way. I tried to do the following, but id returns the count of each group, not of the record set. -----------------------------+ SELECT COUNT(*) AS user_count FROM orders o GROUP BY o.user_id -----------------------------+ So, any suggestions? Or is this just a two part process?? Thanks, .........................
