Sven, for your mental health and the integrity of your database, I strongly
urge you to ignore David's advice. Fix up your app so that it anticipates

Sorry, David, but your posting is 100% "up the spout". You clearly need to

conflicts occur (and why you should WELCOME them!) and -- key to the whole
-- what consititutes an atomic database application task...
