Can you try: select B.* from "Branschkod" B inner join "Branschkod" B2 on B2."Namn" = B."Namn" where B."ECO_ID" <> B2."ECO_ID" order by bb."Kod" to see if Kod's in the 17111 range are getting returned, or if the resultset ends before it reaches that range Regards G ------------------------------------ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Visit http://www.firebirdsql.org and click the Resources item on the main (top) menu.
