从 1 小时前选择的 Sql 查询？

Question

I have this query but I want to change the date to delete everything that is from more than 1 hour ago based on the server time (or if not possible by server time by post date). How do I do that?

DELETE FROM wp_posts
 WHERE post_date < '2008-06-06 19:18:00' 
   AND post_status = 'publish'

Answer 1

Use:

DELETE FROM wp_posts
 WHERE post_date < DATE_SUB(NOW(), INTERVAL '1' HOUR)
   AND post_status = 'publish'

Reference:

• DATE_ADD
• DATE_SUB

Answer 2

Or even simpler:

SELECT NOW() - INTERVAL 1 HOUR;

So the query becomes:

DELETE FROM wp_posts
 WHERE post_date < NOW() - INTERVAL 1 HOUR
   AND post_status = 'publish'

Answer 3

子日期功能也适用！

SELECT subdate(current_timestamp, interval 1 hour)

Answer 4

DELETE from  table where date_add < NOW() - INTERVAL 1 HOUR;

查看运行此 sql 的时间：

select NOW() - INTERVAL 1 HOUR as s1 , NOW() as s2;
