eventos que no funcionan db

Events are run by the scheduler, which is not started by default.
mysql> SHOW PROCESSLIST;
The event_scheduler is running, but it doesn't appear in the list. For me it's better to use
mysql> select @@event_scheduler;
OR, you can also verify using the following command:
mysql> SELECT @@global.event_scheduler;
The result should be ON, otherwise set it off (will get 0 for the command), as stated in the next section
If you don't have any such entry (as above), you may start the event scheduler using the following command:
mysql> SET GLOBAL event_scheduler = ON;
