使用MySQL创建自动执行事件

    xiaoxiao2023-11-12  158

    最近需要删除MySQL数据库中固定时间之前的数据。

    需要实现的功能:每天自动删除三天之前的数据行

    现有环境:

    MYSQL8.0

    数据库:changsan

    数据表:py_url

    具体实现代码为:

    CREATE EVENT AutoDeleteOldNotifications ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 DAY ON COMPLETION PRESERVE DO DELETE  FROM changsan.py_url WHERE c_data < DATE_SUB(NOW(), INTERVAL 3 DAY);
