You can access Microsoft SQL Server 2000 and 2005 databases using the SQL Native Client interface. The SQL Native Client interface uses a DLL named PBSNC125.DLL to access the database. The interface uses the SQL Server 2005 Native Client (sqlncli.h and sqlncli.dll) on the client side and connects using OLE DB.
For SQL Server 2000, the SQL client SDK was provided with the Microsoft Database Access Components (MDAC). MDAC does not support new features in SQL Server 2005. To take advantage of these features, you need to use the SNC interface. The SQL Server 2005 SQL Native Client software must be installed on the client computer.
