檢查在MySQL查詢3米不同的日期範圍

我有一個表值wp_posts包含post_date和author_id列檢查在MySQL查詢3米不同的日期範圍

我需要找到author_id從wp_posts凡在有職位（全部）3時間範圍：

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'

看起來很簡單，但我無法弄清楚。如果我把AND放在每個日期範圍內，總是會返回0.

任何想法？

你爲什麼不把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')

編輯：

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' 
)

這是你需要什麼？

Hello @SubRed。實際上需要根據author_id分組的帖子，它們在所有3個日期範圍內匹配。如果我發現author_id的帖子在一個日期範圍內，我需要忽略他，如果適用於兩個日期範圍，則相同。我只需要，如果author_id在所有3個日期範圍中都有帖子。 – Gude

我編輯了我的答案，但尚未經過測試。 – SubRed

謝謝！解決了！ – Gude

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

試試這個::

(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')
