The NO_DATA_FOUND exception is being raised before you can check SQL%FOUND.

Thanks for your input ebrian. I don't know why No_DATA_FOUND exception before SLQ%FOUND. Do you have any idea.
SQL> select Pat_Nbr
  2  from patient
  3  where Pat_Nbr = 3249;

   PAT_NBR
----------
      3249

Are you really running this as user "SYSTEM"?

  7        Select pat_nbr
  8        Into v_nbr
  9        From Patient
 10        Where v_nbr = nbr;

v_nbr is null at this moment so this will never return a row.

I think this might be "Pat_Nbr" instead of "v_nbr".

In addition, NEVER use SYSTEM (or worst SYS) for your objects, create your own user.

Anyway.

As Brian wrote

so use:


FUNCTION FindPatient(nbr IN Patient.pat_nbr%TYPE)
   Return Boolean IS
   v_nbr Patient.Pat_nbr%TYPE;
Begin
   Select pat_nbr Into v_nbr
   From Patient
   Where pat_nbr = nbr;
   Return True;
EXCEPTION
   WHEN NO_DATA_FOUND THEN 
     Return False;
END FindPatient;
