Wordpress按距离排序和功能后置查询

Question

我正在尝试一个mysql查询来根据距离排序帖子，比如说在半径250英里内，所有的工作都很好，除了我需要以一种方式排序帖子，特色帖子总是在顶部。这是我的mysql查询（我正在wordpress上做）。

    SELECT SQL_CALC_FOUND_ROWS wp_posts.*, ( 3959 * acos( cos( radians(40.140711) ) * cos(      radians( latitude.meta_value ) ) * cos( radians( longitude.meta_value ) - radians(-74.20619299999998) ) + sin( radians(40.140711) ) * sin( radians( latitude.meta_value ) ) ) ) AS distance , 
latitude.meta_value AS latitude , 
longitude.meta_value AS longitude
    FROM wp_posts 
    INNER JOIN wp_postmeta ON (wp_posts.ID = wp_postmeta.post_id) 
    INNER JOIN wp_postmeta AS latitude ON wp_posts.ID = latitude.post_id 
    INNER JOIN wp_postmeta AS longitude ON wp_posts.ID = longitude.post_id 
    WHERE 1=1 
    AND wp_posts.post_type = 'event' 
    AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'recurring') 
    AND (wp_postmeta.meta_key = 'st_date' ) 
    AND latitude.meta_key="geo_latitude" 
    AND longitude.meta_key="geo_longitude" 
    AND wp_posts.ID in (SELECT tr.object_id FROM wp_term_relationships tr JOIN wp_term_taxonomy t on t.term_taxonomy_id=tr.term_taxonomy_id WHERE t.term_id IN ('3','4','5','6','7','8','9','10')) 
    AND (wp_posts.ID IN (SELECT wp_postmeta.post_id FROM wp_postmeta WHERE wp_postmeta.meta_key='st_date' 
    AND date_format(wp_postmeta.meta_value,'%Y-%m-%d') >'2013-09-23 14:35:58')) 
    GROUP BY wp_posts.ID HAVING distance <= 250 
    ORDER BY (SELECT wp_postmeta.meta_value FROM wp_postmeta, wp_posts AS p where wp_postmeta.post_id=p.ID AND wp_postmeta.meta_key = 'featured_h') ASC, distance ASC LIMIT 0, 10

问题是ORDER BY，它给我的错误是“Subquery returns多于1行”

如果删除ORDER BY（从wp_postmeta中选择wp_postmeta.meta_value,wp_posts为p,其中wp_postmeta.post_id=p.id,wp_postmeta.meta_key='featured_h'

它的工作很好，但它没有显示出顶部的fetaured柱子，任何方法来修复它。

Answer 1

在resultset中放置一列，显示featureed状态。我相信，您必须再次加入wp_postmeta才能实现这一点。

然后使用

 ORDER BY status, distance

或者也许

 ORDER BY STATUS='featured', distance

这将把你的特色帖子首先按距离排序，然后是其余的。

（将子查询放在order by子句中是很奇怪的。）
