How to set a maximum execution time for a mysql query?

Question

I would like to set a maximum execution time for sql queries like set_time_limit() in php. How can I do ?

Answer 1

You can find the answer on this other S.O. question:

MySQL - can I limit the maximum time allowed for a query to run?

a cron job that runs every second on your database server, connecting and doing something like this:

• SHOW PROCESSLIST
• Find all connections with a query time larger than your maximum desired time
• Run KILL [process id] for each of those processes
