我们如何创建一个在指定时间段后执行并在指定时间段后结束的MySQL重复事件？
众所周知，重复事件意味着它将在间隔的常规时间后执行，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，在该示例中，我们创建一个事件，该事件每分钟执行一次，一小时后过期-
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());
mysql> Select * from event_message;
