Заметки

You must override this member function to construct or obtain a rowset object and return a handle to it. If you declare your record view class with ClassWizard, the wizard writes a default override for you. ClassWizard's default implementation returns the rowset handle stored in the record view if one exists. If not, it constructs a rowset object of the type you specified with ClassWizard and calls its Open member function to open the table or run the query, and then returns a handle to the object.

Примечание.
Previous to MFC 7.0, OnGetRowset returned a pointer to CRowset. If you have code that calls OnGetRowset, you need to change the return type to the templatized class CRowset<>.

Пример

CFrameWnd* pFrame = (CFrameWnd*)AfxGetMainWnd();
COleDBRecordView* pView = (COleDBRecordView*)pFrame->GetActiveView();

// CProductAccessor is a user-defined accessor class
CRowset<CAccessor<CProductAccessor>>* pRowSet = 
   (CRowset<CAccessor<CProductAccessor>>*)pView->OnGetRowset();
