If you're attempting to connect via ODBC, you need to set up the ODBC source
separately.

On Linux, you would probably install FreeTDS and unixODBC, setting up
/etc/odbc.ini with an entry like this:

[My_SQL2005_Server]
Driver = FreeTDS
Description = SQL2005
Trace = No
Server = PRODSK0322
Port = 1433
Database = TestDB

On Windows, I'm not sure how to set up the ODBC sources.

Then you can connect with:

dbh = DBI.connect("DBI:ODBC:My_SQL2005_Server", "sa", "!Sa123")
