中性能是由语句中的like '%%'引起，并发现字段的特殊性，被查找的数据为path中的“。”分隔内容，故可对sys_org表及字段path用table函数自关联建成物化视图，并且根据实际情况每两个小时刷新一次，具体如下：
create materialized view sysorg_paths
refresh complete
start with sysdate
next sysdate + 1/12
as
(
select t2.*,t1.* from sys_org t1 ,table(split(path,'.')) t2
) ;
create index idx_sysorg_paths on sysorg_paths(s_value);

因生产数据库掌握在我们维护人员手中，为了更好的在线优化，建立带数视图，帮建立了如下包:
create or replace package sysorgpath_view_param
is
function set_param(num number) return number;
function get_param
return number;
end sysorgpath_view_param;
create or replace package body sysorgpath_view_param is
paramValue number;
function set_param(num number) return number is
begin
paramValue:=num;
return num;
end;
function get_param return number is
begin
return paramValue;
end;
end sysorgpath_view_param;
并创建视图如下：
create or replace view sysorg_path_views as
select orgid,orgname from sysorg_paths where s_value=to_char(sysorgpath_view_param.get_param());

中性能是由语句中的like '%%'引起，并发现字段的特殊性，被查找的数据为path中的“。”分隔内容，故可对sys_org表及字段path用table函数自关联建成物化视图，并且根据实际情况每两个小时刷新一次，具体如下：
create materialized view sysorg_paths
refresh complete
start with sysdate
next sysdate + 1/12

因生产数据库掌握在我们维护人员手中，为了更好的在线优化，建立带数视图，帮建立了如下包:
create or replace package sysorgpath_view_param
is
function set_param(num number) return number;
function get_param
return number;
end sysorgpath_view_param;
create or replace package body sysorgpath_view_param is
paramValue number;
function set_param(num number) return number is
begin
paramValue:=num;
return num;
end;
function get_param return number is
begin
return paramValue;
end;
end sysorgpath_view_param;
并创建视图如下：
create or replace view sysorg_path_views as
select orgid,orgname from sysorg_paths where s_value=to_char(sysorgpath_view_param.get_param());
故上述语句可改写如下：
with tmp1 as (select orgid from sys_org so start with

最后把上述语句到生产环境上一试，发现所用时间约为原来的十分之一。其实还可继续用视图简化该语句，用带参视图，以便能够在线调整，以便加相应的查询指示
