oracle创建带参数视图的例子

/* 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 ，当然可定义其它类型
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 ;
