Thanks for the idea, but not quite what I had in mind. I want all of the newest records and ignore older matching records (matching on MailingListId and ListSelectId)

>SELECT TOP 10 MailingListId, ListSelectId, ;
> StateCountAsOF, ;
> StateCountId ;
> FROM StateCount ;
> INTO CURSOR zStateCount;
> ORDER BY StateCountAsOf DESC

>>When I run my SELECT I get the most current date but the field ListSelectId (which is a key into another table is for another record). I tried GROUP BY MAX(StateCountAsOf) and HAVING BY MAX(StateCountAsOf) but get syntax errors. I can't use StateCountId in my GROUP BY because I then get all records (since it is the key field).
