Hi, Sohaid : thank you for the suggestion, I can see the query string now. It did add range like this: SELECT FIRSTFAST * FROM LedgerTrans WHERE LedgerJournalTrans.TransDate=LedgerTrans.TransDate AND LedgerJournalTrans.Voucher=LedgerTrans.Voucher NOTEXISTS JOIN FIRSTFAST * FROM LedgerTransSettlement WHERE LedgerTrans.RecId = LedgerTransSettlement.TransRecId and after I use Joathan's advice , it did clear the range.(I made a mistake before) SELECT FIRSTFAST * FROM LedgerTrans NOTEXISTS JOIN FIRSTFAST * FROM LedgerTransSettlement WHERE LedgerTrans.RecId = LedgerTransSettlement.TransRecId Thank you very much! Johnny
