oracle 临时表使用例子并用CURSOR返回结果集的例子
包中带过程 要自己定义一个type [t_cursor] is ref cursor游标，返回的时候就直接 PROCEDURE find_scan_diff_date(dept_code tb_bar_recode.dept_code%TYPE,
oper_start_tm varchar2,
oper_end_tm varchar2,
oper_type_code tb_bar_recode.oper_type_code%TYPE,
c_ref OUT t_cursor);
存储过程 用系统默认的 sys_refcursor 游标类型 定义变量就OK了
1：生成包
--生成包
CREATE OR REPLACE PACKAGE pkg_bar_scan_diff IS
/*TYPE waybillnotype IS RECORD(
waybill_no tb_bar_recode.waybill_no%TYPE);*/
TYPE t_cursor IS REF CURSOR /*RETURN waybillnotype*/;
PROCEDURE find_scan_diff_date(dept_code tb_bar_recode.dept_code%TYPE,
oper_start_tm varchar2,
oper_end_tm varchar2,
oper_type_code tb_bar_recode.oper_type_code%TYPE,
c_ref OUT t_cursor);
END pkg_bar_scan_diff;
2：生成包体
--生成包体
CREATE OR REPLACE PACKAGE BODY pkg_bar_scan_diff IS
/**
* 1 ：根据点部代码，扫描类型，扫描时间 查出所有的扫描单号的母单号 并插入临时表；
* 2 ：查出所有的 母单和子单;
* 3 ：业务数据查询功能 可扩展;
