SQL Server Native Client (OLE DB) Reference
The SQL Server Native Client OLE DB provider exposes interfaces to consumers wanting access to data on one or more computers running SQL Server. The SQL Server Native Client OLE DB provider is an OLE DB version 2.0–compliant provider.
This SQL Server Native Client OLE DB provider programming reference does not document all of the OLE DB interfaces and methods, only those interfaces and methods that exhibit provider-specific behavior when using the SQL Server Native Client OLE DB provider.
For a full description of the core OLE DB interfaces and methods, see the OLE DB Programmer's Reference.
