Question

我已将事件记录创建为root用户，而GLOBAL event_scheduler也是ON 我的事件过程查询是：

DELIMITER $$

CREATE 
    EVENT `near_end_warranty` 
    ON SCHEDULE EVERY 1 HOUR
    DO BEGIN

        DECLARE numrow int;
        SELECT COUNT(id) FROM equipments WHERE TIMESTAMPDIFF(WEEK,NOW(),warranty_end_date)<5 AND TIMESTAMPDIFF(WEEK,NOW(),warranty_end_date)>0 INTO numrow;

        IF numrow>0 THEN
        INSERT INTO notifications (eq_id,start_date,end_date,name,type,message,created_by,modified_by,created_on,modified_on)
        SELECT eq_id,warranty_start_date,warranty_end_date,'warranty','ending soon','warranty ends soon for','System','System',NOW(),NOW()
        FROM equipments WHERE TIMESTAMPDIFF(WEEK,NOW(),warranty_end_date)<5 AND TIMESTAMPDIFF(WEEK,NOW(),warranty_end_date)>0;
        END IF;

    END $$

DELIMITER ;

我的活动状态是：

我正在尝试根据条件从设备表中获取多行，并按小时插入到通知表中。我在07:11创建了此事件，其9:52已经创建并且未插入任何行进行通知表yet.warranty_end日期：2015-05-20关于两排设备表，今天的日期是2015-05-08，所以必须在通知表中添加两行。这里可能出现什么问题？

Answer 1

我实际上发现了确切的问题，在表的字段名称和查询中有轻微的错误，我现在已经解决了它，一切都运行得很好。

MySQL事件没有按计划执行任务？
