Where would you place the 2nd GROUP BY? Does this work in SQL databases [Oracle, SQL Server], or just a VFP feature? I am fairly certain you can not do this [both Group By and referencing] in Oracle, but I will certainly try this out when I get back to work next week.

>>In a UNION, you can only have 1 GROUP BY and 1 ORDER BY and each has to e after the last UNION SQL. You also have to reference the GROUP BY and ORDER BY items by number. How about something like:

>>select Field1, sum(Field2) from Table1;
>>     where Field3 <> "XXX";
>>union select Field1, sum(Field2) from Table2;
>>     where Field3 <> "XXX";
>>     and Field1 not in (select field1 from table1);
>>     group by 1
