How do I kill all the processes in Mysql “show processlist”?

Question

Because I see a lot of processes there, and the \"time\" column shows big values for all of them.

Answer 1

KILL ALL SELECT QUERIES

select concat('KILL ',id,';') 
from information_schema.processlist 
where user='root' 
  and INFO like 'SELECT%' into outfile '/tmp/a.txt'; 
source /tmp/a.txt;
