An int datatype and an int syntax are two distinct objects too :-)
That's precisely the job of the JDBC driver to convert datatypes I pass
in into their representation with the correct syntax that backend would
understand.

I would have no use of the driver doing anything else - what's the point
in passign data in if the syntax it gets converted into isn't understood
by the server?
