SYS_REFCURSOR在存储过程中的再次调用.

如下存储过程

CREATE OR REPLACE PROCEDURE P_TESTA (
PRESULT OUT SYS_REFCURSOR
)
AS
BEGIN
OPEN PRESULT FOR SELECT * FROM USERS;
END P_TESTA;

想在另外的存储过程中接收我的结果集  在输出中应该定义什么类型

SQL> create or replace procedure P_TESTB
  2  as
  3  v_result sys_refcursor;
  4  type a_type is table of a%rowtype;
  5  v_a a_type;
  6  begin
  7    P_TESTA(v_result);
  8      fetch v_result bulk collect into v_a;
  9      for i in v_a.first .. v_a.last loop
10        dbms_output.put_line(v_a(i).id);
11      end loop;
12  end;
13  /

Procedure created

SQL> set serveroutput on;
SQL> execute p_testb;
