MDAC 2.5 SDK - OLE DB Providers
OLE DB Provider for SQL Server
SQLOLEDB, the Microsoft® OLE DB Provider for SQL Server, exposes interfaces to consumers wanting access to data on one or more computers running Microsoft SQL Server™.
When developing an OLE DB consumer, select a provider developed for the data source to consume. Use SQLOLEDB to develop an optimized OLE DB consumer for SQL Server databases.
SQLOLEDB is an OLE DB version 2.0–compliant provider.
The provider passes the command statements (such as SQL-92 and Transact SQL) through to the server. Invalid commands are rejected by the server.
