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 ，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 ;
