Call Stored Procedure from Forms 6i -- Urgent Plz...

Question

Dear All,
I am first writing a stored procedure as:-
CREATE OR REPLACE FUNCTION
good_hire
(birthdate_in IN DATE,
reqsal_in IN NUMBER)
RETURN BOOLEAN
IS
too_young BOOLEAN :=
ADD_MONTHS
(SYSDATE, -216) >
birthdate_in;
too_expensive BOOLEAN :=
reqsal_in > fin.dept_bal;
BEGIN
RETURN NOT (too_young
OR too_expensive);
END;
Now in my forms also i have the same function,which i defined in in my program unit i.e., with the same name good_hire,but with different parameters.
If I want to call this stored procedure(good_hire)in my form
I am writing this code in the pre-Insert trigger.
IF good_hire
(:newemp.birthdate,
:newemp.proposed_sal)
THEN
SELECT empseq.NEXTVAL
INTO :newemp.empno
FROM dual;
ELSE
RAISE FORM_TRIGGER_FAILURE;
END IF;
Notice that i am sending bind variables from my form to the
stored procedure. Now my question :
1) Can i pass bind variables to the stored procedures from
forms or is there any other way i can access the
stored roceures from forms(Expecting a detailed answer) and
from which triggers can I access the stored procedures(like pre-
Insert here)?
2) If at all I have the same parameters in my program unit
function and with the same name good_hire, I know that the code
in the pre-Insert trigger will call only the function in my
program unit and not the stored procedure, but if I like to
call my stored procedure instead of the local function good_hire
then what should I do?
2)As I said before if i have different parameters, for the
stored procedure good_hire and local function good_hire and If
I call good_hire from my pre-insert trigger .. Is it that the
Forms will decide and call the Local function or stored
procedure depending on the parameter list?
I hope all my points are very clear.
I am expecting the best and detailed answer for my
Queries, I also hope these Quests will clear the doubts of many
members in our esteemed group.
Thnx in Advance...

Answer 1

Dear Siree,
Oh!! how many Questions? Each how much big??
Ok First of all the answer to your first question.
You can use the Stored procedures in the same way as the Forms procedures. You can pass bind variables to the stored procedures as well. You can also use the stored procedures in any triggers, I think there are no restrictions for that. The only thing is you should be connected to database while compiling the trigger where you are calling the stored procedure.
Answer to your second question.
You cannot direct Forms (I don't know about version 10g), untill 9i, you cannot tell forms to take the stored procedure and leave the local procedure. It will always take the local procedure, once a procedure is called. If not found locally then only it will go for the Stored procedures.
For your third question.
As I told you b4 forms searches for the procedure being called locally first, if locally present, does not go to the stored procedure. If declared by different paramaters in the stored procedure and it is called, then it will throw error (as it first searches for the name locally and if found will take up the one present locally and since that procedure is with different parameter, will throw up error). It is after all a stupid machine and can't think like us.
