早上执行语句：

update report_user_info set cell = replace(cell,’”‘,’’) where id<10000;

就报了标题上面的错误。

然后我去查找原因是因为我早上的一个动作导致 report_user_info表锁住了。

方法1：

mysql -uroot -pmypassword -e”show processlist”|grep -i “locked”

| 103466 | root | localhost | report_user | Killed | 9646 | query end | update report_user_info set cell = replace(cell,’”‘,’’) | 0 | 15885184 | 15885185 |

方法2：

show engine innodb status\G

show processlist;

kill掉这个进程：

mysql> kill 103466 ;
Query OK, 0 rows affected (0.00 sec)

当然，可能造成死锁的事务比较的大，他在processlist里面驻留的时间比较的长。
