Планировщик событий в Mysql не работает

Question

Я написал планировщик событий в MySQL. После выполнения этого события это не работает вообще. Задача, которая написана, не происходит. Ниже мой планировщик событий, DELIMITER $$

CREATE EVENT `Untravelled_Deduction` ON SCHEDULE EVERY 1 DAY STARTS '2016-04-01 06:42:00' ON COMPLETION NOT PRESERVE ENABLE DO BEGIN

Не удалось исправить эту проблему, необходимо предложить какие-либо улучшения.

Создание событий недостаточно.

Убедитесь, что планировщик фактически включен:

MariaDB [(none)]> show global variables like 'event_scheduler'; 
+-----------------+-------+ 
| Variable_name | Value | 
+-----------------+-------+ 
| event_scheduler | OFF | 
+-----------------+-------+ 
1 row in set (0.00 sec) 

Если нет, попробуйте активировать его во время выполнения:

SET GLOBAL event_scheduler = ON; 

или

SET @@global.event_scheduler = ON; 

Или в/и т.д./мой .conf (или где бы вы ни находились) и перезапустить сервер:

event_scheduler=ON
