MySQL 事件未按计划执行任务？

Question

我已以 root 用户身份创建事件日志记录，并且 GLOBAL event_scheduler 也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 ;

我的事件状态是:

Db:db_medisup
Name:near_end_warranty
Definer:root@localhost
Time zone:SYSTEM
Type:RECURRING
Execute at:NULL
Interval value:1
Interval field:HOUR

Ends:NULL

Originator:1
character_set_client:utf8
collation_connection:utf8_general_ci

我正在尝试根据条件从设备表中获取多行，并每小时插入到通知表中。我于 07:11 创建了此事件，已经是 9:52，尚未将任何行插入到通知表中.warranty_end date:2015-05-20 在两行设备表上，今天的日期是 2015-05-08，因此必须将两行添加到通知表中。这里可能有什么问题？

我实际上找到了确切的问题，表的字段名称和查询时有一点错误，我现在已经解决了它，一切都运行得很完美。
