Transform a Query into a procedure or a trigger

Question

Hello All
How could i put this Query in a procedure or function to call it from form a form
*SELECT ADD_MONTHS (TO_DATE ('01/01/2001', 'dd/mm/yyyy'), (12 * 4) + 3)*
  *FROM DUAL* Then the value should be added in multiple rows in a loop
CREATE OR REPLACE TRIGGER emp_alert_trig
    BEFORE INSERT ON emp
FOR EACH ROW
BEGIN
    DBMS_OUTPUT.PUT_LINE('New years employees experience periods 2 be added');
END; Regards,
Abdetu...

I have to admit that it's a bit disconcerting that you don't seem to want to invest any time in solving your own problems while hoping that some volunteers will happily solve the problem for you.
That said, I'm afraid that I don't understand what you are looking for.
How could i put this Query in a procedure or function to call it from form a formWhat does "form" mean in this context? Oracle Forms? APEX? Something else? Forms is a bit of a special case because you may be talking about client-side PL/SQL.
SELECT ADD_MONTHS (TO_DATE ('01/01/2001', 'dd/mm/yyyy'), (12 * 4) + 3)
FROM DUAL So you want to create a function that returns a constant? Why bother with all the calculations? Maybe you're looking for
CREATE FUNCTION get_hard_coded_date
  RETURN date
IS
BEGIN
  RETURN ADD_MONTHS (TO_DATE ('01/01/2001', 'dd/mm/yyyy'), (12 * 4) + 3);
END;I'm somewhat hard pressed to understand how that might be useful to anyone, but that's the closest thing to what you're asking that I can come up with.
Then the value should be added in multiple rows in a loopOK. Now you've totally lost me
CREATE OR REPLACE TRIGGER emp_alert_trig
    BEFORE INSERT ON emp
FOR EACH ROW
BEGIN
    DBMS_OUTPUT.PUT_LINE('New years employees experience periods 2 be added');
END;And I have no idea what this trigger has to do with anything that came before. Particularly since the trigger isn't doing anything (I certainly hope that you're not expecting that dbms_output.put_line is going to cause text to appear in your application).
