I don't know how that happened but I think that's right:
select of the row after insert returned ID=2,
but somehow subsequent call to sequence's nextval returned 216.
In the docs I discovered "select lastval()" which seems to behave exactly
like @@Identity in Sybase returning the latest nextval that was obtained in
the current session by no-matter-which sequence.
That's exactly the functionality I need - much easier to use because no need
to track the name.
Can you think of any reason why using "select lastval()" would be a bad
idea?
Thanks a lot,
Andrei
