Agreed. But at the end of the day, the difference is what exactly? Wouldn't auditing (short of sql logging) say “no
change”with respect to “me” column?
This then is a client issue, no? There has to be two paths in the client code, one which generates an update without
“me”and one which includes “me" and the second path does not take in to account current value. If it’s worth the
effortthe latter code path needs to be cognizant of the current state of the record (“me” column).
