To modify the opened recordset, you need to use the Filter/Find/Seek/Sort method of the Recordset. Note that to be able to use these methods, your recordset must be client-sided (CursorLocation = adUseClient).

It is often faster to add the Where clause to SQL query to retreive only needed data and then requery the database for the new data needed!
