大于（>）在mysql查询中不起作用

Question

I'm trying to run a query on my WordPress database to get a list of all posts and some other data from a certain month. I'm running into an issue with post_date , where looking for posts before a certain date works fine, but looking for posts after a certain date returns 0 results.

This example returns 0 results:

SELECT * FROM `wp_posts` WHERE `post_date` > '2014-01-01 00:00:00';

However this returns a ton of results:

SELECT * FROM `wp_posts` WHERE `post_date` < '2014-01-01 00:00:00';

There are posts published after 2014-01-01, so that's not the problem.

Any ideas?

Answer 1

在存在日期列的表中检查您的列数据类型

Answer 2

如果您要评估的只是日期，请尝试将该字段转换为日期：

SELECT * FROM wp_posts WHERE CAST(post_date AS DATE) > '2014-01-01'

Answer 3

Try this i think it will be useful

SELECT * FROM wp_posts WHERE post_date '< 2014-01-01 00:00:00';
