众所周知，重复事件意味着它将在固定间隔时间后执行并在指定时间到期。为了说明此类事件的创建，我们使用以下示例，其中我们正在创建一个每分钟执行一次并在一小时后到期的事件 −
mysql> CREATE EVENT testing_event10 ON SCHEDULE EVERY 1 MINUTE STARTS CURRENT_TIMESTAMP ENDS CURRENT_TIMESTAMP + INTERVAL 1 HOUR DO INSERT INTO event_message(message,generated_at) Values('Recrring evnts',NOW());
Query OK, 0 rows affected (0.00 sec)
mysql> Select * from event_message;
