天空八部SF–清理垃圾帐号及仓库垃圾清理方法

按登陆日期清理垃圾帐号及仓库垃圾清理方法
提醒你先备份你的数据库,以防万一.备份好后,打开你的SQL查询分析器,对muonline数据库进行操作:

1.select * into membstat from memb_stat where connecttm>年/月/日(这里按格式输入你要删除什么日期后没登陆过的帐号)

2.truncate table memb_stat

3.insert into memb_stat select * from membstat

4.select * into membinfo from memb_info where memb___id in
(select memb_info.memb___id
from memb_info,membstat
where memb_info.memb___id=membstat.memb___id)

5.truncate table memb_info

这里注意要先将memb_info表的memb___id列的identity属性去掉.

6.insert into memb_info select * from membinfo

修改回memb___id列的identity属性

这里要先修改accountcharacter表的id列的排序规则,在规则里把区分大小写也选中,同时去掉Number列的identity属性,否则下面的插入操作无法进行

7.select * into accountchbak from accountcharacter where id in
(select accountcharacter.id
from accountcharacter,membstat
where accountcharacter.id=membstat.memb___id)

8.truncate table accountcharacter

9.insert into accountcharacter select * from accountchbak

这里将上面修改过的规则和属性修改回来

修改character表accountid列的排序规则.方法同上面一样.

10.select * into characterbak from character where accountid in
(select character.accountid
from character,membstat
where character.accountid=membstat.memb___id)

11.delete from character

12.insert into character select * from characterbak

改回排序规则.

下面是删除仓库空的和重复记录
13.delete from warehouse where items is null

14.select distinct * into warehousebak from warehouse

15.select accountid from warehousebak group by accountid having count(*)>1

16.truncate table warehouse

17.insert into warehouse select * from warehousebak

最后把不再需要的备份和临时表删除:warehousebak,characterbak,accountchbak,membinfo,membstat.

上面的步骤和方法我自己已经用过没有出现什么问题,不过还是建议大家先备份好自己的数
