SQL & PL/SQL

Hi all,
In the following piece of code:

SELECT count(*) 
    INTO v_count_name 
    from fnd_lobs
    where file_name = v_file_name
  ;
  
  
  IF nvl(v_count_name,0) > 1 
    THEN 
      DELETE FROM fnd_lobs WHERE FILE_ID = P_FILE_ID;
      COMMIT;
        raise_application_error(-20101, 'Duplicate file name!');
        RETURN;
  end if;

When the error is produced in the application i'm receiving the following:

-20101 : ORA-20101: Message 20101 not found;
product=RDBMS; facility=ORA
ORA-01403: no data found

...instead of my error message specified...


Any ideas?
