I have imported 2 datasets into 2 tables from excel into access (dataset1 and dataset2). There are 3 fields on each dataset that I need to join (address1, address2, zipcode). What I then need to do is where "fullname" from dataset2 does not match any of the names listed in any of the joined rows. How would we go about this. So I want the results to return where address fields match, instances where name does not match in any of the joined rows.
