Mysql兩張表的關聯欄位不一致

標籤：field   arch   exit   arc   問題   out   gis   lap   upd   

工作中遇到了一個問題，郵件系統群發失敗，後來經過排查尋找到了原因

原來是因為mysql中的兩張表的關聯欄位竟然不一致，

表A

mysql> desc rm_user_router;
+------------+-------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+------------+-------------+------+-----+---------+-------+
| CORPID | int(10) | NO | PRI | NULL | |
| LOGINNAME | varchar(60) | NO | PRI | NULL | |
| UIN | int(10) | NO | MUL | NULL | |
| SPID | int(10) | NO | | NULL | |
| MIID | int(10) | NO | | NULL | |
| ASID | int(10) | NO | | 0 | |
| FLAG | int(1) | NO | | 0 | |
| REGISTERID | varchar(60) | NO | | NULL | |
| STATUS | int(2) | NO | | NULL | |
| RES1 | int(10) | NO | | 0 | |
| RES2 | int(10) | NO | | 0 | |
| CREATETIME | datetime | NO | | NULL | |
+------------+-------------+------+-----+---------+-------+

表B

mysql> desc rm_group_info;
+----------------+---------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+----------------+---------------+------+-----+---------+-------+
| UIN | int(10) | NO | PRI | NULL | |
| CORPID | int(10) | NO | MUL | NULL | |
| GROUPID | varchar(60) | NO | | NULL | |
| GROUPNAME | varchar(32) | YES | | NULL | |
| MAXMEMBERNUM | int(10) | YES | | 0 | |
| CURMEMBERNUM | int(10) | YES | | 0 | |
| STATUS | int(2) | YES | | 0 | |
| FLAG | int(2) | YES | | 0 | |
| RECVTYPE | int(2) | YES | | 0 | |
| CREATETIME | datetime | NO | | NULL | |
| MODIFYTIME | datetime | NO | | NULL | |
| WHITELIST | varchar(2000) | YES | | NULL | |
| BLACKLIST | varchar(2000) | YES | | NULL | |
| join_privilege | int(10) | YES | | 0 | |
| exit_privilege | int(10) | YES | | 0 | |
| is_auto | int(1) | NO | | 0 | |
+----------------+---------------+------+-----+---------+-------+

其中兩張表的UIN欄位竟然不一致，現在需要解決的是rm_group_info表格中的groupnam欄位的uin要和rm_user_router表格中的loginname欄位的uin要一致

1.先備份2張表

2.更新同步資料

update rm_user_router inner join rm_group_info on rm_user_router.loginname=rm_group_info.groupname set rm_group_info.uin=rm_user_router.uin;
