Hi John,

I'm guessing that your sum is different for each row. Union will only eliminate rows that are completely identical.

>When I issue a SQL-Select like the following:

> group by Field1

>The result table will consistantly contain one record for each Field1 value except for one duplicate.

>Does anyone know how to get no duplicates?
