Unfortunately, I don't think this module is the right one for you without making changes to it.
BUT there is an interesting website that may or may not help you. Check this out
Unix and MSSQL. There are several alternatives out there.. but you may be interested in
Sybperl. From the site:
Sybperl is the collective name for three different modules: DBD::Sybase, Sybase::CTlib and Sybase::DBlib. DBD::Sybase is a DBI driver using CT-Library, while the other two offers direct interfaces to the client library. As MSSQL::DBlib evolved from Sybase::DBlib, it would not be too much of a task to retarget MSSQL::Sqllib to use this library instead. In that case, you could use MSSQL::Sqllib.. but you'd need to modifiy it to fit your needs. You may want to use
DBD::ODBC instead. Anyways, I hope this helps a bit. Wouldn't it be awesome if MS could interface a bit with Unix. (I guess.. when pigs fly.. who knows..)
Update: The documentation for DBD::FreeTDS is
here
