Sometimes during a SNAFU I have to run kill query xxxxxxx twenty or thirty times. Any sort of kill all command I am missing?

On account of how I don't like typing.

restart the server? – Derek Downey May 10 '11 at 18:21
@DTest - can that be done with a query? I don't have direct server access. – JIStone May 10 '11 at 18:23
This is a question that can come in handy for other developers and DBAs (+1) !!! – RolandoMySQLDBA Jun 20 '11 at 21:25

From the Linux command line

for PROC_TO_KILL in `mysql -h... -u... -p... -A --skip-column-names -e"SHOW PROCESSLIST" | grep -v "system user" | awk '{print $1}'` ; do mysql -h... -u... -p... -A --skip-column-names -e"KILL QUERY ${PROC_TO_KILL}" ; done

You can change the grep option in the header of the for loop to locate a specific user or specific string in the query.

If you have MySQL 5.1 where the processlist is in the INFORMATION_SCHEMA, you can do this to generate the KILL QUERY commands in bulk from within the mysql client:

FROM information_schema.processlist WHERE user<>'system user'\G

You can do WHERE clauses against the INFO field to look for a specific query, the TIME field against long running queries, or the DB field against a specific database.

mysql> select concat('KILL ',id,';') from information_schema.processlist where user='root' into outfile '/tmp/a.txt';
Query OK, 2 rows affected (0.00 sec)

mysql> source /tmp/a.txt;
Query OK, 0 rows affected (0.00 sec)

I actually like this approach because it can be done within the confines of the mysql client regardless of Linux or Windows. +1 !!! – RolandoMySQLDBA May 2 '12 at 20:23
