1205 Lock wait timeout exceeded try restarting transaction

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"

 TOO MANY LOCKS PRINTED FOR THIS TRX: SUPPRESSING FURTHER PRINTS

  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。
