I too have answered this question many times, and
BBQ is right on the money.
Connecting to databases can be confusing, especially trying to use Win32::ODBC.
If you intend to work on other platforms, then start learning the DBI now, and you
will be greatly rewarded for your effort (not like it's hard to learn) :).
Otherwise, if you just need a quick and dirty way to get at data in an existing
database with an existing DSN connection then look at this
node
which states the same thing I just said above and shows how to use ADO from Perl.
Good question though. Good luck!
