Thanks in advance for your replies.
I have a data table which loads a few fields including 2 fields - owner and user.
The file belongs to the owner but any user can work on it, owners can also be users.
I need to flag users who do not exist in owners field
What I need but cannot figure out is something like
SELECT from user WHERE they do not exist in owner on any row at all, ever (so exclude owners from users list)
I tried with exists function but no joy
Hope this makes sense
