If only it were like this :) . I have asked about this behavior long 
time ago. Unfortunately the DB API of kamailio does not say '0 rows 
affected' when update is performed. It says only if the update was 
successful or not. No indication if it has actually found a match or 
not. And actually I don't see this possibility in the mysql library either:
