Answer 1

Declare
returned_refcursor SYS_REFCURSOR := Null;
Begin
BL_EMPLOYEE_PROJECT(some_emp_id, returned_refcursor);
-- variable returned_refcursor now has a pointer to the CUR from procedure
End;
Here is a simple example
create or replace PROCEDURE AA(
EMP_ID IN VARCHAR2,
CUR OUT SYS_REFCURSOR)
IS
BEGIN
OPEN CUR FOR
Select * From
(
SELECT '12' "ID", 'Name for 12' "NAME" FROM DUAL UNION ALL
SELECT '13' "ID", 'Name for 13' "NAME" FROM DUAL
)
WHERE ID = EMP_ID;
END;
-- Use it
Declare
returned_refcursor SYS_REFCURSOR := Null;
myId VarChar2(10);
myName VarChar2(20);
Begin
AA('12', returned_refcursor);
-- variable returned_refcursor now has a pointer to the CUR from procedure
Fetch returned_refcursor InTo myID, myName;
DBMS_OUTPUT.PUT_LINE(myId);
DBMS_OUTPUT.PUT_LINE(myName);
End
-- Result
-- anonymous block completed
-- 12
-- Name for 12
