我从我的Linux shell连接到mysql。我时不时地运行一个太大的SELECT查询。打印啊打印啊,我已经知道这不是我的意思。我想停止查询。
按Ctrl+C(几次)完全杀死mysql,带我回到shell,所以我必须重新连接。
是否有可能在不杀死mysql本身的情况下停止查询?

连接mysql
mysql -uusername -p -hhostname
显示完整的流程列表:
mysql> show full processlist;
+---------+--------+-------------------+---------+---------+------+-------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
+---------+--------+-------------------+---------+---------+------+-------+------------------+
| 9255451 | logreg | dmin001.ops:37651 | logdata | Query | 0 | NULL | show processlist |
+---------+--------+-------------------+---------+---------+------+-------+------------------+
终止特定的查询。id = 9255451
mysql> kill 9255451;
如果你的权限被拒绝,试试下面的SQL:
CALL mysql.rds_kill(9255451)

这个问题的作者提到,通常是在 MySQL打印它的输出,他意识到执行了错误的查询。 如上所述,在这种情况下,Ctrl-C不起作用。然而,我注意到它 将中止当前查询-如果你捕捉它之前任何输出是 打印出来。例如:
mysql> select * from jos_users, jos_comprofiler;
MySQL忙于生成上面两个表的笛卡尔积 你很快就会注意到MySQL并没有将任何输出输出到屏幕上(进程 状态是发送数据),所以你输入Ctrl-C:
Ctrl-C -- sending "KILL QUERY 113240" to server ...
Ctrl-C -- query aborted.
ERROR 1317 (70100): Query execution was interrupted
Ctrl-C可以类似地用于停止UPDATE查询。
再补充一下
删除查询**Id** where Id是连接Id从显示processlist
如果您不想在运行某些应用程序时终止连接,则更可取。

如果你有mysqladmin可用,你可以得到查询的列表:
> mysqladmin -uUSERNAME -pPASSWORD pr
+-----+------+-----------------+--------+---------+------+--------------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
+-----+------+-----------------+--------+---------+------+--------------+------------------+
| 137 | beet | localhost:53535 | people | Query | 292 | Sending data | DELETE FROM |
| 145 | root | localhost:55745 | | Query | 0 | | show processlist |
+-----+------+-----------------+--------+---------+------+--------------+------------------+
然后你可以停止运行这个长时间查询的mysql进程:
> mysqladmin -uUSERNAME -pPASSWORD kill 137
