小编Ars*_*ngh的帖子

嗨,那么首先,我不是mysql查询的专家.我有拖表wp_posts和wp_wti_like_post和我做LEFT JOIN对wp_wti_like_post ON wp_posts.ID = wp_wti_like_post.post_id 和SUM(wp_wti_like_post.value) < 2但如果no row在wp_wti_like_post同岗位的ID从wp_posts那么它不会显示甚至从行wp_posts,只是忽略它,请帮助这个真的需要它.

查询:

SELECT * 
FROM wp_posts
LEFT JOIN wp_wti_like_post ON wp_posts.ID = wp_wti_like_post.post_id
WHERE wp_posts.post_status =  'publish'
GROUP BY wp_wti_like_post.post_id
HAVING SUM( wp_wti_like_post.value ) <2
OR SUM( wp_wti_like_post.value ) = NULL 
LIMIT 0 , 200

表wp_wti_like_post

所以我有以下功能来获取我的帖子,但我希望用户直接在帖子有"今天"日期的页面上,这不是事件发布日期,而是事件发生的日期,就像我有事件一样man_date字段2015-4-12和今天是2015-4-12我将直接看到该事件的页面,而不在第一页上的那些事件.
