You can't as long as there is nothing on which you could sort the records. With only these two columns the result will never be sure

When you open a recordset using ADO (Microsoft) then you may use the method "MoveLast" in order to jump to the last record in a recordset.
There is nothing like that in pure SQL unless you use a cursor. Using cursors allows you to do the same things s you would do in an ADO recordset.
See the doc that came with your database to see how to create and use cursors.
