Well, not entirely. That's tricks like @@identity etc. are for, I
understand.
Once on a customer's demand I've rewritten half of the EOF database
level to support this for an EOF/Cocoa application; I am not sure it
would be possible in WO/Java, but it might. Was a proper nightmare and
heaps of legwork even in Objective C (where, if you happen not know
the language, things generally go about thousand times easier than in
the Java thing), but at the very end it worked pretty well, reliably
and efficiently, and I have to admit there's something to the
approach. For one, it makes a co-operation with non-EOF-based tools
working on the same set of databases ways and ways easier and more
robust...
Best,
