OLE DB Programmer's Reference

///////////////////////////////////////////////////////////////// // myCreateSession // // Create an OLE DB session object from the given data source // object. The IDBCreateSession interface is mandatory, so this // is a simple operation. // ///////////////////////////////////////////////////////////////// HRESULT   myCreateSession    (    IUnknown *           pUnkDataSource,    IUnknown **          ppUnkSession    ) {    HRESULT              hr;    IDBCreateSession *   pIDBCreateSession = NULL;        //Create a session object from a data source object.    XCHECK_HR(hr = pUnkDataSource->QueryInterface(              IID_IDBCreateSession, (void**)&pIDBCreateSession));    XCHECK_HR(hr = pIDBCreateSession->CreateSession(              NULL,               // pUnkOuter              IID_IOpenRowset,    // riid              ppUnkSession ));    // ppSession              CLEANUP:    if( pIDBCreateSession )       pIDBCreateSession->Release();    return hr; }
