Can we use Column Names in Parameter Cursor

Question

Hi
can we use Column Names in Parameter Cursor??
DECLARE
CURSOR Emp_Cur (P_Deptno NUMBER)
IS
SELECT Empno, Ename
FROM Emp
WHERE Deptno = P_Deptno;
BEGIN
FOR Emp IN Emp_Cur(10)
LOOP
DBMS_OUTPUT.PUT_LINE('The Employee Number is: '||emp.Empno);
DBMS_OUTPUT.PUT_LINE('The Employee Name is: '||emp.Ename);
END LOOP;
FOR Emp IN Emp_Cur(20)
LOOP
DBMS_OUTPUT.PUT_LINE('The Employee Number is: '||emp.Empno);
DBMS_OUTPUT.PUT_LINE('The Employee Name is: '||emp.Ename);
END LOOP;
END;
In the above Program, I send Deptnumber. If i send Column names like Empno, Ename. What can i do??
If Declare Samething Through Parameter Cursor, it doesn't accept VARCHAR2(Size)

Answer 1

For parameters you don't use size, just the type (DATE, NUMBER, VARCHAR2, CLOB, ...)
DECLARE
  CURSOR Emp_Cur (P_Ename VARCHAR2)
  IS
    SELECT Empno, Ename
    FROM Emp
    WHERE Ename = P_Ename;
BEGIN
  FOR Emp IN Emp_Cur('SCOTT')
  LOOP
    DBMS_OUTPUT.PUT_LINE('The Employee Number is: '||emp.Empno);
    DBMS_OUTPUT.PUT_LINE('The Employee Name is: '||emp.Ename);
  END LOOP;
END;
