What would you do if you had a MEMO field as part of the non aggregate statement in VFP7. I can't return MAX of that. Nor can I add that to the GROUP BY statement. Is there any other way to make it aggregate?

>In your example, which, if I understand correctly, only 1 first and last name can possibly be returned with name_line1, this syntax would appear to be redundant. In most cases, it isn't.
