My whole point is that this thread is a waste of breathe.
Conceputaly the finer the granularity of locks acheived, the better the application
will
behave and the easier it is to implement an OLTP application.

He's saying that there are other things that Sybase does well, inspite of not
havingrow level locking. Would you care to elaborate. It was the same point I was

That's the real test.
