Ucenter 1.5 快速升级到 1.6 版本的办法

从 Discuz! 老版本升级到 Discuz! X2 的时候，必须把 Ucenter 升级到 1.6 版本。

在升级 Ucenter 的时候，由于要对短信息表进行操作，数据量很大的同学往往会觉得升级时间过长，甚至有时候还卡住不动了。

由于 Ucenter 到 1.6 的升级主要是操作数据库，那么，有独立服务器的同学可以采用执行SQL语句的办法进行升级。

先备份 Ucenter 所在的数据库，然后一步一步执行以下语句，注意 Ucenter 的数据库前缀，如果不一样的话需要改改前缀：

建表语句：

1. 
   
2. DROP TABLE IF EXISTS pre_ucenter_pm_members;
   
3. CREATE TABLE pre_ucenter_pm_members (

升级：

1、生成 pm_plists 表基础数据

1. INSERT INTO `pre_ucenter_pm_lists`
   
2. (authorid, pmtype, subject, members, min_max, dateline,lastmessage)
   
3. SELECT * from (SELECT msgfromid as authorid, 1 as pmtype, '' as subject, 2 as members,
   
4. CONCAT(LEAST(msgfromid,msgtoid),'_',GREATEST(msgfromid,msgtoid)) as min_max, dateline,
   
5. CONCAT('a:3:{s:12:"lastauthorid";s:',LENGTH(msgfromid),':"',msgfromid,'";s:10:"lastauthor";s:',LENGTH(msgfrom),':"',msgfrom,'";s:11:"lastsummary";s:',LENGTH(message),':"',LEFT(IF(LENGTH(subject) > 0 AND STRCMP(subject, message), CONCAT(subject, '\r\n', message), message),150),'";}') as lastmessage
   
6. FROM `pre_ucenter_pms`
   
7. WHERE related = 1 order by dateline desc) as tmp GROUP BY min_max;

复制代码

2、生成 pm_members 表基础数据

1. INSERT INTO `pre_ucenter_pm_members` (plid, uid, isnew, lastupdate) SELECT plid, SUBSTRING_INDEX(min_max, '_', 1), 0, 0 FROM `pre_ucenter_pm_lists`;
   
2. INSERT INTO `pre_ucenter_pm_members` (plid, uid, isnew, lastupdate) SELECT plid, SUBSTRING_INDEX(min_max, '_', -1), 0, 0 FROM `pre_ucenter_pm_lists`;

复制代码

3、生成 pm_indexs 表数据，增加一个字段 pmidold，升级后删除此字段

1. INSERT INTO `pre_ucenter_pm_indexes` (plid, pmidold) SELECT l.plid, p.pmid FROM `pre_ucenter_pms` p LEFT JOIN `pre_ucenter_pm_lists` l ON CONCAT(LEAST(p.msgfromid, p.msgtoid), '_', GREATEST(p.msgfromid, p.msgtoid)) = l.min_max WHERE p.related = 1;

然后用 Ucenter 1.6 的文件覆盖原文件即可，不需要再执行升级操作。

这个我可不会

不是直接有升级文件可以升级的吗？？

支持哈了{:soso_e182:}
