Yes, ADO is native for MS Access. But you may try ADO without ADO Express (dbGo), DAO or even OLEDB or ODBC - this way you will have no TDataSet descendant but you should have some speed improvement. By default, ADO Express uses client-side cursor - it fetches all rows into memory cache, so 1/20 sec. for one select is normal. //------------------------------------------ Regards, Vassiliev V.
