NP, I know Oracle is a drag.... but that's what the client has.
Perhaps if you could clarify why I'm confused I might be able to help
debug. (I've stepped through expression.py all day long). I feel
like I just need a little hint or push in the right direction.
Eventually you get to a cx cursor and call execute with the statement
on it. How does the same statement/parameter combo fail with SQL
generate, yet succeed using `text` or plain cx? If I can get over
that hump, I think I might be able to give you a patch.
