Yes, if you want to use mixed case.

Yeah, that'll just tell you that its SQL_LONGVARCHAR or whatever. As a
general rule, apps will just ask for whatever they want and the driver
will conver as best it can.

In your case, it'd probably be easier to use the ANSI driver, then of
course you know there's no Unicode in sight.

It converts to the system ANSI (CP_ACP) using WideCharToMultiByte
(http://msdn.microsoft.com/library/de...y/en-us/intl/u
nicode_2bj9.asp) iirc.
