MySQL event not triggering [duplicate]

题

I've created the following event, but for some reason it's not getting triggered:

CREATE EVENT Del_logs
ON SCHEDULE EVERY 1 HOUR
DO
    TRUNCATE TABLE security.errors;

Is there any log I could check to see what went wrong?

解决方案

It looks like the event scheduler is OFF.

use SHOW PROCESSLIST to check if the event scheduler is enabled. If it's ON you should see a process "Daemon" by user "event_scheduler".
use
```
SET GLOBAL event_scheduler = ON;
```
to enable the scheduler if it's currently not enabled.
