检查Mysql查询中是否有3个不同日期范围的值

我有一个表

wp\u posts

，其中包含

post\u date

和

author\u id

列

我需要从

wp\u posts

中找到

author\u id

，其中有（全部）3个时间范围的帖子：

wp_posts.post_date BETWEEN '2012-11-05 00:00:00' AND '2012-11-10 23:59:59'
wp_posts.post_date BETWEEN '2012-11-12 00:00:00' AND '2012-11-17 23:59:59'
wp_posts.post_date BETWEEN '2012-11-19 00:00:00' AND '2012-11-25 23:59:59'

看起来很简单，但我搞不懂。 如果我在每个日期范围之间放置AND，将始终返回0

有什么想法吗？

试试这个：

SELECT author_ID
FROM posts
WHERE   (wp_posts.post_date BETWEEN '2012-11-05 00:00:00' AND '2012-11-10 23:59:59') OR
        (wp_posts.post_date BETWEEN '2012-11-12 00:00:00' AND '2012-11-17 23:59:59') OR
        (wp_posts.post_date BETWEEN '2012-11-19 00:00:00' AND '2012-11-25 23:59:59')
GROUP BY author_ID
HAVING COUNT(*) = 3

(wp_posts.post_date BETWEEN '2012-11-05 00:00:00' AND '2012-11-10 23:59:59') or
(wp_posts.post_date BETWEEN '2012-11-12 00:00:00' AND '2012-11-17 23:59:59') or
(wp_posts.post_date BETWEEN '2012-11-19 00:00:00' AND '2012-11-25 23:59:59')

你为什么不放上或：

(wp_posts.post_date BETWEEN '2012-11-05 00:00:00' AND '2012-11-10 23:59:59') OR 
(wp_posts.post_date BETWEEN '2012-11-12 00:00:00' AND '2012-11-17 23:59:59') OR
(wp_posts.post_date BETWEEN '2012-11-19 00:00:00' AND '2012-11-25 23:59:59')

这就是你需要的吗？

Hello@SubRed。实际上，a需要按作者id分组的帖子，这与所有3个日期范围相匹配。如果我发现一个作者id在1个日期范围内有帖子，我需要忽略他，如果在2个日期范围内也一样。我只需要当作者id在所有3个日期范围内都有帖子时才需要。

SELECT author_id FROM wp_posts
WHERE author_id IN (
    SELECT author_id FROM wp_posts WHERE post_date BETWEEN '2012-11-05 00:00:00' AND '2012-11-10 23:59:59'
) AND author_id IN (
    SELECT author_id FROM wp_posts WHERE post_date BETWEEN '2012-11-12 00:00:00' AND '2012-11-17 23:59:59'
) AND author_id IN (
    SELECT author_id FROM wp_posts WHERE post_date BETWEEN '2012-11-19 00:00:00' AND '2012-11-25 23:59:59'
)
