Thanks all who replied. I added an autonumber ID to the table. 1) Extracted all matching records to a temp table. 2) Added an autonumber ID so I could uniquely point to any given record. 3) Created qFirstID where I Grouped By the address hash and pulled the First(ID) That gave me the correct subset of records where there is only one ID for each address. 4) Joined that ID from qFirstID with tblOrder on the ID in qOrderFirstID 5) Selected all the name / address fields and viewed them to ensure no dupes. NO DUPES. 6) Used that to export the data Again thanks for the suggestions. I really have to write up a document of how I do this stuff!!! John W.

I need to send only one piece of mail to that address, the person doesn't matter. John Colby, Some Street, SomeCity, SomeState, SomeZip Mary Colby, Some Street, SomeCity, SomeState, SomeZip John Doe, Some Other Street, Some Other City, Some Other State, Some Other Zip Mary Doe, Some Other Street, Some Other City, Some Other State, Some Other Zip I don't care whether I send to Mary or John, I only care that only a single piece of mail goes to each address. Select distinct of course acts on the entire row and so returns all 4 names. I do have an address hash that generates a hash string for just the address part. So it seems like something like a group by address hash and then a top1 is the right direction, but of course it has to be the TOP 1 in each GROUP. I could (and might have to to get this out) write a little VBA routine to do this but I would rather use a SQL solution. So how is this done in SQL. John W.
