Calling stored procedure from page process and PLS-00049 error?

Question

Good morning guys!
I'm dealing with several problems this morning! The one that I need to deal with first is the following.
I created the page process (see below: 1st code) in order to validate if all records where LNG_GEBIET matches have the status 3 or 4. If that is the case I want to call the procedure "set_status_arbeit_zu_gebiet". If amountrs and countstat do not match, then nothing is supposed to be done.
The problem lies within the stored procedure itself. I receive a PLS-00049 bind variable error for :new.LNG_GEBIET.
Can you please tell me what I forgot to declare in code 2 below???
Thank you guys!
The page process:
Declare
  amountrs    number;
  countstat   number;
begin
SELECT COUNT(*) INTO amountrs FROM TBL_PUNKTDATEN where LNG_GEBIET = :P4_CNT_GEBIET;
SELECT COUNT(*) INTO countstat FROM TBL_PUNKTDATEN where LNG_GEBIET = :P4_CNT_GEBIET and INT_STATUS = 3 or LNG_GEBIET = :P4_CNT_GEBIET and INT_STATUS = 4;
    IF amountrs = countstat THEN
     set_status_arbeit_zu_gebiet;
    ELSE
     dbms_output.put('nothing');
    END IF ;
end;Code 2 with the true problem!
CREATE OR REPLACE PROCEDURE set_status_arbeit_zu_gebiet
IS
    cursor c2 is select LNG_GEBIET from TBL_ARBEIT_ZU_GEBIET where PNUM = 1114 and LNG_GEBIET=:new.LNG_GEBIET;
    v_c2  c2%ROWTYPE;
BEGIN
   open c2;
fetch c2 into v_c2;
if c2%notfound then
        INSERT INTO TBL_ARBEIT_ZU_GEBIET
        LNG_GEBIET,
          LNG_ARBEITSSCHRITT,
          PNUM,
          INT_BEARBEITER,
          DATE_DATUM,
          GEPL_DATUM
        VALUES
        (:new.LNG_GEBIET,
         52,
         1114,
         895,
         sysdate,
         to_date('01.01.1990', 'DD.MM.YYYY')
        commit;
        close c2;
END set_status_arbeit_zu_gebiet;One more question: Is it possible to integrate the first validation that calls my stored procedure into code 2?
Thanks for you time!

Answer 1

The error is in following statement:
INSERT INTO TBL_ARBEIT_ZU_GEBIET ( ... ) VALUES ( :new.LNG_GEBIET, ... );
As the statement is part of a procedure and not trigger so it is not able to bind this variable with any value.
As a resolution, pass this value to the procedure from the process and use it in the insert statement.
The process will have following IF statement:_
IF amountrs = countstat THEN
set_status_arbeit_zu_gebiet *(:P4_CNT_GEBIET)*;
ELSE
dbms_output.put('nothing');
END IF ;
and the procedure will be as follows:_
CREATE OR REPLACE PROCEDURE set_status_arbeit_zu_gebiet *(p_lng_gebit varchar2)*
IS
cursor c2 is select LNG_GEBIET from TBL_ARBEIT_ZU_GEBIET where PNUM = 1114 and LNG_GEBIET= --:new.LNG_GEBIET-- p_lng_gebit ;
v_c2 c2%ROWTYPE;
BEGIN
INSERT INTO TBL_ARBEIT_ZU_GEBIET ( ... )
VALUES
( --:new.LNG_GEBIET--  p_lng_gebit, ... );
END set_status_arbeit_zu_gebiet;
