我们如何创建一个在特定时间段后执行并于特定时间段后结束的 MySQL 循环事件?
我们知道重复事件意味着它将按规律的时间间隔执行,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,我们创建的事件将在每分钟执行一次,并在一个小时后到期 -
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()); Query OK, 0 rows affected (0.00 sec) mysql> Select * from event_message; +----+----------------+---------------------+ | ID | MESSAGE | Generated_at | +----+----------------+---------------------+ | 1 | Hello | 2017-11-22 17:05:22 | | 2 | Hi | 2017-11-22 17:08:37 | | 3 | Recrring evnts | 2017-11-22 20:14:00 | | 4 | Recrring evnts | 2017-11-22 20:15:00 | | 5 | Recrring evnts | 2017-11-22 20:16:00 | | 6 | Recrring evnts | 2017-11-22 20:17:00 | | 7 | Recrring evnts | 2017-11-22 20:18:00 | | 8 | Recrring evnts | 2017-11-22 20:19:00 | +----+----------------+---------------------+ 8 rows in set (0.00 sec)
