I don't really like the way that the Sybase client libraries work, but I've heard they work equally well.

The Sybase libs will NOT work against MS-SQL 2k, because MS changed the login sequence so the fallback to the TDS 4.2 protocol fails (TDS 4.2 is supposed to be the lowest common denominator in the TDS protocol stack, and should be supported by both Sybase and MS.)

BTW - what don't you like with the Sybase libs?

Update: dragonchild /msg'd me to say that this node was a bit confusing. What I mean is that the Sybase Client Libraries can't be used to connect to MS-SQL 2k. However, FreeTDS works fine (with some limitations), so DBD::Sybase can certainly be used when built with the FreeTDS libraries.
