Cursors
Client-Side Cursor
The consumer specifies client-side cursors by setting the Cursor Location property of the connection object to adUseClient.
When the consumer specifies a client-side cursor, ADO uses the Client Cursor Engine (CCE) that is part of Microsoft Data Access Components (MDAC). The CCE is an OLE DB rowset implementation.
For more information on the Client Cursor Engine, refer to the MSDN documentation.
