The OLE DB Driver for SQL Server exposes interfaces to consumers wanting access to data on one or more computers running SQL Server. The OLE DB Driver for SQL Server is an OLE DB version 2.0-compliant provider.
This OLE DB Driver for SQL Server 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 OLE DB Driver for SQL Server.
For a full description of the core OLE DB interfaces and methods, see the OLE DB Programmer's Reference.
