oracle 定义带参数的视图

1、定义包

CREATE OR REPLACE package p_view_param  is
--定义开始日期--
   function set_beginTime(beginTime varchar2) return varchar2;
   function get_beginTime return varchar2;
--定义结束日期--
   function set_endTime(endTime varchar2) return varchar2;
   function get_endTime return varchar2;

end p_view_param;
/

2、定义包体

create or replace package body p_view_param is
       parambeginTime varchar2(20);
       paramendTime varchar2(20);
       -- Param
       function set_beginTime(beginTime varchar2) return varchar2 is
       begin
         parambeginTime:=beginTime;
         return beginTime;
        end;  

       function get_beginTime return varchar2 is
       begin
         return parambeginTime;
       end;
       -- Type
       function set_endTime(endTime varchar2) return varchar2 is
       begin
         paramendTime:=endTime;
         return endTime;
        end;  

       function get_endTime return varchar2 is
       begin
         return paramendTime;
       end;  

   end p_view_param; 

3、定义参数视图

create or replace view p_view_num as

查询方法：

SELECT * FROM p_view_num WHERE p_view_param.set_beginTime('2017-01-01')='2017-01-01' and p_view_param.set_endTime('2017-05-01')='2017-05-01'
