Mysql 如何选择比一周更新的行？

使用MariaDB 10，我想查询过去一周文章的

article

表：

我的问题是：

SELECT * FROM article WHERE category="News" AND created_at < NOW() - INTERVAL 1 WEEK ORDER BY created_at DESC;

---

如何实现这一点？

逻辑是反向的。您想要的是

而不是

+-------------+-----------------+------+-----+-------------------+----------------+
| Field       | Type            | Null | Key | Default           | Extra          |
+-------------+-----------------+------+-----+-------------------+----------------+
| id          | int(6) unsigned | NO   | PRI | NULL              | auto_increment |
| title       | varchar(150)    | NO   |     | NULL              |                |
| content     | mediumtext      | NO   |     | NULL              |                |
| created_at  | timestamp       | NO   |     | CURRENT_TIMESTAMP |                |
| category    | varchar(64)     | NO   |     | test              |                |

SELECT a.*
FROM article a
WHERE category = 'News' AND
      created_at > NOW() - INTERVAL 1 WEEK
ORDER BY created_at DESC;
