@Im_PJ, the difference between the driver options “MS SQL Server” & “MS SQL Server/Sybase” is that one is for Windows hosts and one is Linux/Mac hosts.
These might be better labeled as MS SQL - sqlsrv & MS SQL - dblib.
Still waiting to hear back if Sybase is supported “out of the box” (I suspect not.)
The ODBC driver integration you referenced has not to my knowledge been implemented yet.
