Thanks, this is close. It eliminates those that are ONLY in secondary group 12 (i.e. those where membergroupids = "12" but does not eliminate those that are in both groups 12 and 13 (i.e. membergroupids = "12,13") and maybe some other combinations that I haven't checked.

We need, not an inequality but a "not found in" check.

[Edit] I see you edited yours while I was writing the above reply. I'll try your additional suggestion and get back...

Sadly, no go. Doesn't return anybody.

But combining the two approaches, it looks, on first blush, like this does work:

SELECT email, username
FROM user
WHERE usergroupid =2
AND membergroupids NOT LIKE '%12%'

I'll have to spot check a few users of known multiple group memberships, but so far I think that'll do it. Thanks for your help.
