REF CURSOR in PL/SQL BLOCK

Question

I am trying to return a ref cursor from a function in a package. I am trying to execute this through SQL Plus and cannot seem to get the code correct this is what I have. Please help. How do I display the output? I tried a CURSOR FOR loop, but got syntactical error saying it was being used inproperly.
DECLARE
     v_rec      adp_vsp.grc_vsp;
     v_fname ps_personal_data.first_name%TYPE;
     v_lname ps_personal_data.last_name%TYPE;
BEGIN
     v_fname := 'John';
     v_lname := 'Barr';
     v_rec := adp_vsp.f_get_vsp(v_fname,v_lname);
END;

Answer 1

If you want to do it manually, you need to loop through the cursor and fetch the results:
sql>create or replace procedure p_show_emps(p_rc out sys_refcursor)
  2  is
  3  begin
  4    open p_rc for select empno, ename from emp where rownum <= 5;
  5  end;
  6  /
Procedure created.
sql>declare
  2    v_rc     sys_refcursor;
  3    v_empno  emp.empno%type;
  4    v_ename  emp.ename%type;
  5  begin
  6    p_show_emps(v_rc);
  7    loop
  8      fetch v_rc into v_empno, v_ename;
  9      exit when v_rc%notfound;
10      dbms_output.put_line( v_empno || ', ' || v_ename );
11    end loop;   
12    close v_rc;
13  end;
14  /
