Yeah, I had a feeling about the parse statements thing. I think you found a
bug.

FYI, the "parse statements" option was added before we had the 6.4 protocol.
The newer protocol passes the size of the fields back in a query, which is
something the old 6.3 protocol did not do. So I wrote this grand parse routine
which would take a query and go ask the database about all the fields. The
"parse statements" still has an advantage over the 6.4 protocol, in that it can
find out about whether a field in a query can be "null" or not. Plus, it can
find out about column alias names. Unfortunately, I don't think the parse
statements can handle some of the newer syntaxes that will be introduced in
6.5.

To be honest, I don't think the driver should be parsing sql statements too
much anyway.
