i have designed a search query screen with four fileds-empno,ename,hiredate1,hiredate2 . .if i enter some empno in empno field it has to retrieve all the emps belong to that number . .the same applies to remaining also . . in order to do this requirement i have tried a key next item on ename field . . just to see whether it works or not . . .
there are no errors but when i enter the ename in field and run it is displaying as FRM-40505: ORACLE error: unable to perform query.Can anyone rectify this.
