What exactly is this data supposed to represent? Apparently you want to sum pairs of rows: SELECT A.autonumber, B.autonumber A.value+B.value AS tot FROM tbl AS A LEFT JOIN tbl AS B ON A.autonumber + 1 = B.autonumber WHERE A.autonumber IN (1,3,5,7,9) ; (untested) The problem is that you can't prevent gaps in the sequence of values in an auto-numbered IDENTITY column. So there is no guarantee that each row will have a "next" row. -- David Portas, SQL Server MVP Whenever possible please post enough code to reproduce your problem. Including CREATE TABLE and INSERT statements usually helps. State what version of SQL Server you are using and specify the content of any error messages.

| Ummm, why A.autobaris + 4 if you want an increment of 7? shouldnt you specify A.autobaris + 6?
