Procedure with Array IN parameter

Question

Hi,
I have requirement to create a procedure that accepts an Array as IN parameter , Query a table using this array and return the result as refcursor .
please suggest the best approach . i tried to get it as below but not working .
CREATE OR REPLACE TYPE ARR_ID AS TABLE OF VARCHAR2(20);
CREATE OR REPLACE
PROCEDURE TEST_ARRAY
(P_ARR_ID IN ARR_ID,
P_CUR_OUT OUT SYS_REFCURSOR)
AS
BEGIN
OPEN P_CUR_OUT FOR
SELECT * FROM EMPLOYEE WHERE EMP_ID IN (SELECT * FROM TABLE(P_ARR_ID ));
END;

I am not questioning design, but there is nothing wrong with your SP. For example:
SQL> CREATE OR REPLACE TYPE ARR_ID AS TABLE OF VARCHAR2(20);
  2  /
Type created.
SQL> CREATE OR REPLACE
  2  PROCEDURE TEST_ARRAY
  3  (P_ARR_ID IN ARR_ID,
  4  P_CUR_OUT OUT SYS_REFCURSOR)
  5  AS
  6  BEGIN
  7  OPEN P_CUR_OUT FOR
  8  SELECT * FROM HR.EMPLOYEES WHERE EMPLOYEE_ID IN (SELECT * FROM TABLE(P_ARR_ID ));
  9  END;
10  /
Procedure created.
SQL> VARIABLE refcur REFCURSOR
SQL> EXEC TEST_ARRAY(ARR_ID(100,110),:refcur);
PL/SQL procedure successfully completed.
SQL> PRINT refcur
