If MSFT is being honest, they claim there is no remaining Sybase code in SQL Server 2005. FWIW. There may not be anything recent on Sybase, but maybe if you searched for comparisons between Oracle and MS SQL Server you might have better luck. MS SQL is based on an earlier version of Sybase, but I believe that since then, both have independently added row-level locking, which Oracle had long ago. Dennis Williams
