使用MySQL根据日期字段自动删除行
[英]auto delete rows according to a date field using mysql
问题描述
I have a table with a field end date . 
我有一个字段end date的表。 I would like that all rows that contain a record in the end date field get deleted when the date is passed. 我希望在日期过去时删除在end date字段中包含记录的所有行。
Once I have the right msyql syntax/command, I can make a cron job from it. 一旦有了正确的msyql语法/命令，就可以从中进行cron作业。
Can anyone help me out? 谁能帮我吗？ Thanks in advance! 提前致谢！

DELETE FROM table WHERE end_date IS NOT NULL 从表WHERE end_date IS NOT NULL删除
end_date field must be null for those records that should not be deleted. 对于那些不应删除的记录，end_date字段必须为null。

或类似这样的东西：
DELETE FROM db_table WHERE end_date<NOW() AND end_date IS NOT NULL
