我有一个wp_posts包含post_date和author_id列的表

我需要找到（所有）3个时间范围内的author_id帖子wp_posts：

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，但我想不通。如果我在每个日期范围之间放置 AND，将始终返回 0。

有任何想法吗？

你为什么不放 OR：

(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')

编辑：

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'
)

这是你需要的吗？

GROUP BY author_ID
HAVING COUNT(*) = 3

尝试这个 ：：

(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')
