Deart gurus ! I'm just wondering what happens in this situation : i issue the following SQL : update AAA set BBB=0 where ROWID='XXXXXXXXX' ; Now , if the value of the BBB column is already 0 for the given row (or a set of rows) , what will actually happen behind the curtains ? I mean, will Oracle somehow detect that actually the update does not need to occur , or will it perform the update regardless of the current values of the columns .
