方法一： Package 和 Procedure 的做法
先创建一个返回结果集的游标：
create or replace package pkgaccq_tbuserpr
is
type result is ref cursor;
end pkgaccq_tbuserpr;
用上面定义的结果集来乘放抛出的结果结：
create or replace procedure praccq_tbuserpr
(
cresult in out pkgaccq_tbuserpr.result ------引用定义的package cursor
)
is
begin
open cresult for
select * from tb_color;
end praccq_tbuserpr;
方法一： Package 和 Package Body 的做法
Package :
create or replace package pgaccq_tbuser is
---public type declaration
type result is ref cursor;
procedure prq_tb_user(ocur_result in out result);
end pgaccq_tbuser;
Package Body:
create or replace package body pgaccq_tbuser is
procedure prq_tb_user(ocur_result in out result)
is
begin
open ocur_result for
select * from tb_user;
end prq_tb_user;
end pgaccq_tbuser;
