Oracle创建带有参数的视图代码介绍

/ 按个人需要定义，我定义三个参数 ，因我项目程序需要，所以三个参数都是number ，可定义其它类型
但切记，第二个create 的参数类型等需以第一个create一致，否则程序包创建失败
/
create or replace package p_view_param is 
    --参数一
  function set_param(num number) return number; 
  function get_param return number;
  --参数二
  function set_Type(num number) return number; 
  function get_Type return number;
  --参数三
  function set_Id(num number) return number; 
  function get_Id return number;
  end p_view_param; 
--
 create or replace package body p_view_param is 
    paramValue number; 
    paramType number; 
    paramId number; 
    -- Param
    function set_param(num number) return number is 
    begin 
     paramValue:=num; 
     return num; 
    end; 
    function get_param return number is 
    begin 
     return paramValue; 
    end; 
    -- Type
    function set_Type(num number) return number is 
    begin 
     paramType:=num; 
     return num; 
    end; 
    function get_Type return number is 
    begin 
     return paramType; 
    end;
    -- ID
    function set_Id(num number) return number is 
    begin 
     paramId:=num; 
     return num; 
    end; 
    function get_Id return number is 
    begin 
     return paramId; 
    end;
  end p_view_param;

定义视图，where 后面跟参数，可自己拼装，注意视图字段要和select的字段匹配
/
CREATE OR REPLACE VIEW abstract_sum_view(fa_id, aircraft_num,aircraft_weight,airline_code,anchor_pos)
      AS SELECT f.fa_id, f.aircraft_num,findweight(f.aircraft_num),f.airline_code,f.anchor_pos
      FROM tb_flight_abstract f
       where f.fa_id=p_view_param.get_Id(); --参数
--使用视图，传参
 select  from abstract_sum_view where p_view_param.set_id(3)=3 ;
