The current Microsoft ODBC SQL Server Driver is not certified for useagainst Sybase SQL Servers.
As noted in the documentation that comes with the Microsoft SQL Server ODBCDriver, the 2.00.1912 or later versions of the Microsoft drivers arecertified for use only with Microsoft SQL Servers (the 2.00.1912 drivershipped with SQL Server 4.21a). Though older versions of the Microsoft SQLServer ODBC Driver could be connected to older versions of Sybase SQLServers, if you now need to connect to Sybase SQL Servers you shouldcontact ODBC vendors who are in the market of providing drivers for Sybase.The current ODBC drivers provided by Microsoft are optimized to work withMicrosoft SQL Server and depend on features present in the Microsoftproduct.
If you need to connect to Sybase SQL Servers, you can still do so by usingSQL Server ODBC drivers available from other vendors. You can contactSybase Corporation for drivers certified for use against Sybase SQLServers. Many third party ODBC vendors also provide ODBC drivers certifiedfor use against Sybase. Some of the third party drivers can be used toconnect to both Microsoft and Sybase SQL Servers.
