Discuz X3.4 用户表主表存档表数据合并教程-LonHowe Blog

1，登录后台，工具，计划任务，取消勾选每日用户表优化

2，关闭站点，备份数据库，如果可以，全站备份更好

3，不要手贱去点后台，站长，用户表优化

4，打开你的MYSQL管理工具，比如 phpMyAdmin

几个受影响需要更改的表

pre_common_member
pre_common_member_archive

pre_common_member_count
pre_common_member_count_archive

pre_common_member_field_forum
pre_common_member_field_forum_archive

pre_common_member_field_home
pre_common_member_field_home_archive

pre_common_member_profile
pre_common_member_profile_archive

pre_common_member_status
pre_common_member_status_archive

pre_common_member

pre_common_member_archive

pre_common_member_count

pre_common_member_count_archive

pre_common_member_field_forum

pre_common_member_field_forum_archive

pre_common_member_field_home

pre_common_member_field_home_archive

pre_common_member_profile

pre_common_member_profile_archive

pre_common_member_status

pre_common_member_status_archive

5，看一下上面数据库中的几个表，受影响了几个，受影响的都要修改

打开 pre_common_member_archive

删除重复内容

ALTER IGNORE TABLE pre_common_member_archive ADD UNIQUE INDEX(`uid`)

1	ALTER IGNORE TABLE pre_common_member_archive ADD UNIQUE INDEX(`uid`)

复制代码

把 pre_common_member_archive 内容复制到 pre_common_member

insert into pre_common_member select * from pre_common_member_archive

1	insert into pre_common_member select * from pre_common_member_archive

复制代码

再删除主表重复内容，清空存档表内容

上面做完基本就没事了，有强迫症的可以删除带有Archive的空表，备份的bak表都可以删除。

删除带有Archive的空表，更新缓存的时候出现这个错误，而且注册不了（在注册的最后一步会出现不跳转的情况）

(1146) Table 'db_web411070.common_member_archive' doesn't existSELECT COUNT(*) FROM common_member_archive

1	(1146) Table 'db_web411070.common_member_archive' doesn't existSELECT COUNT(*) FROM common_member_archive

在站长—数据库—升级(Discuz! 数据库升级 - 请将数据库升级语句粘贴在下面:)中执行语句：

为了数据安全执行该语句前建议备份数据

DELETE FROM `pre_common_setting` WHERE `skey` = 'membersplit';

1	DELETE FROM `pre_common_setting` WHERE `skey` = 'membersplit';

若没有找到执行语句的输入窗口则修改

config/config_global.php

当中的

$_config[admincp][runquery] 设置修改为 1

(为了安全执行完该语句后确认解决了1146错误后再将配置该回来 ) 刷新后再输入执行。

方法2：

后台，站长，数据库，升级

insert into pre_common_member select * from pre_common_member_archive;

insert into pre_common_member_count select * from pre_common_member_count_archive;

insert into pre_common_member_field_forum select * from pre_common_member_field_forum_archive;

insert into pre_common_member_field_home select * from pre_common_member_field_home_archive;

insert into pre_common_member_profile select * from pre_common_member_profile_archive;

insert into pre_common_member_status select * from pre_common_member_status_archive;

insert into pre_common_member select * from pre_common_member_archive;

insert into pre_common_member_count select * from pre_common_member_count_archive;

insert into pre_common_member_field_forum select * from pre_common_member_field_forum_archive;

insert into pre_common_member_field_home select * from pre_common_member_field_home_archive;

insert into pre_common_member_profile select * from pre_common_member_profile_archive;

insert into pre_common_member_status select * from pre_common_member_status_archive;

以上六条的意思就是把六个存档表中的东西合并到主表中。

然后再使用如下升级数据库：

TRUNCATE TABLE  `pre_common_member_archive`;

TRUNCATE TABLE  `pre_common_member_count_archive`;

TRUNCATE TABLE  `pre_common_member_field_forum_archive`;

TRUNCATE TABLE  `pre_common_member_field_home_archive`;

TRUNCATE TABLE  `pre_common_member_profile_archive`;

TRUNCATE TABLE  `pre_common_member_status_archive`;
