Tricks

1. MySQL Event Scheduler does not work

• First check the event scheduler status:

select @@event_scheduler;

show variables like 'event_scheduler';

show events;

show processlist;

• One-time open:

SET GLOBAL event_scheduler = ON;

• Permanent open:

  For WAMP , add event_scheduler=on under [mysqld] in my.ini. Restart the WAMP services, the event shall begin to execute.

2. Environment configuration for sending email from WAMP server with fake sendmail
