Yea, I just convinced myself of that. The first time I read the docs, that's
what I thought. Then I convinced myself when I re-read them that it was just a
warning, and a new transaction was started. But I just tried it, and they're
not...
Thanks for point that out to me. I dare say that the BEGIN documentation is
unclear to me, even knowing what I know now. Why not just explictly say "Nested
transactions are not supported", rather than "... The current transaction is
not affected". Alright, maybe I still read at Junior High level.
Cheers,
Rob
