create or replace package p_view_param is  function set_param(num varchar2) return number;  function get_param return varchar2;end p_view_param;create or replace package body p_view_param is  paramValue varchar2(4000);  function set_param(num varchar2) return number is  begin    paramValue := num;    return 0;  end;  function get_param return varchar2 is  begin    return paramValue;  end;end p_view_param;视图中获取参数create or replace view viewname asselect * from tablename where aa=p_view_param.get_param();调用时如下select * from viewname where p_view_param.set_param('dd')=0
