MDAC 2.5 SDK - OLE DB Providers
OLE DB Provider for ODBC
The ODBC Provider is compliant with version 1.5 and later of the OLE DB Specification, which is included in the Microsoft® Data Access Components SDK.
Make sure that you use the latest version of ODBC (ODBC 3.51) with the ODBC Provider. However, this provider is not compliant with ODBC 3.0 and later; it supports different Tabular Data Stream processing than other providers. For full functionality against an SQL Server data source, use the OLE DB Provider for SQL Server.
