mysql数据库批量操作

批量KILL会话：

1.首先，根据条件将查询到要kill的进程写入文件；如：
desc information_schema.processlist;

SELECT concat('KILL ',id,';') FROM information_schema.processlist WHERE user='root'; 或者根据status

SELECT concat('KILL ',id,';') FROM information_schema.processlist WHERE user='root' INTO OUTFILE '/tmp/a.txt';

2.然后倒入这个文件，即可kill掉mysql进程：
source /tmp/a.txt;

into table test_table
fields terminated by ',' optionally enclosed by '"' escaped by '"'
lines terminated by '\r\n';
