Hello Chuck;
Thanks for the overview on that one.
No deferred constraints. Sigh. DB2 just dropped a notch in the
respect that I had for it.
I'm actually not 100% sure on the deferred RI checks for DB2 so
leave the respect in place for now! I was wondering if somebody
here knows?
I Googled it when you said that as it surprised me. The answer I
found was that it did not.
I see DB2 has a feature to turn constraints off/on inside a
transaction so I am guessing it would be possible to create a
JDBCAdaptor subclass that automatically did that sort of thing when
it goes to perform adaptor operations on a channel.
Yes, that would be possible. But does that mean you can commit data
that violates the constaints?
