ID will always equal ID, so this query will match every record in the INVENTORY table. If you want to find duplicates, you'll need to do a self-join. Something like this might work - I obviously haven't tested it, though, and it usually takes me a couple of tries to write a query to detect duplicates. SELECT i1.pcname, i1.ip, i1.serialnumber, i1.oldpcnumber, i1.newpcnumber FROM inventory i1 INNER JOIN inventory i2 ON i1.id > i2.id WHERE i1.pcname = i2.pcname AND i1.ip = i2.ip AND i1.serialnumber = i2.serialnumber AND i1.oldpcnumber = i2.oldpcnumber AND i1.newpcnumber = i2.oldpcnumber Dave Watts, CTO, Fig Leaf Software http://www.figleaf.com/ Fig Leaf Software provides the highest caliber vendor-authorized instruction at our training centers in Washington DC, Atlanta, Chicago, Baltimore, Northern Virginia, or on-site at your location.
