Hi,
Is there a way to differentiate between Sybase and SQL Server
other than by the TDS protocol version?

I need an implementation of SQLDescribeCol(), but the information
about column is located in a different table for those DBMSes.
I can probably check what TDS version is used for a connection,
but it is not very reliable way of doing things.

Thank you.
