In my Microsoft Access 2007 database, have a 2 Tables, tblA & tblB. Each has columns FirstName & LastName. I would like to be able to compare the combination of FirstName & LastName columns in both tables & find out which combinations of FirstName & LastName in tblA are not present in tblB. I have tried using the Unmatched query wizard but keep getting an empty recordset, however, I know there are combinations of FirstName & LastName in tblA that are not present in tblB. Thanks for your help & attention.
