How to display the return value of a function in a text field

Question

Hi,
I have 2 textfields in a page.
i> Empno
ii> Salary
The requirement is,
i. Enter an Employee No.
ii. On click of the 'SUBMIT' button a process would be executed which calls a function (or procedure with out parameter) which returns the Salary of the given Employee.
iii. Need to display the salary to the 2nd textfield (Salary).
Here is my process:
i. If procedure call-- :P2_X is a page text field and out parameter.
begin
Pri_test_PROC(:P2_EMPNO,:P2_X);
end;ii. If Function call --
begin
:P2_X:=Pri_test_PROC(:P2_EMPNO);
end;
Issue:
The process is not getting executed and returning the process error message.
Could anyone please give me a pointer, how to overcome the issue. Or if this is not the right way, then what is the work around.
Regards
Antara

Answer 1

Antara,
1. Clue about the error - yes, when I see the error message.
2. What happens if you try to create a procedure like this:
CREATE OR REPLACE PROCEDURE fetch_sal (in_emp IN NUMBER, out_sal OUT NUMBER)
IS
BEGIN
   FOR c IN (SELECT sal
               FROM emp
              WHERE empno = in_emp)
   LOOP
      out_sal := c.sal;
   END LOOP;
END;and then run this in SQL Plus:
DECLARE
   v_sal   VARCHAR2 (20);
BEGIN
   fetch_sal (7839, v_sal);
   DBMS_OUTPUT.put_line (v_sal);
END;What do you get displayed?
