I have a table wp_posts which contains post_date and author_id columns

I need to find the author_id from wp_posts where has posts in (all) 3 time ranges:

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'

Looks simple, but I can’t figure out.
If I put AND between every date range, will always return 0.

Any ideas?

    Why don’t you put 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')

    EDIT:

    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'
)

    Is this what you need?
