WordPress p2pカスタムクエリ

Question

私はMySQLテーブルを持っており、のカラム値はp2p_from（53,126）と問い合わせる必要があります。

どのようなクエリが機能しますか？

ID p2p_from p2p_to 

0 53   215 
1 129  12 
2 124  9 
3 18   215 
4 15   5 
5 126  215 

AND $wpdb->posts.ID = $wpdb->p2p.p2p_to 
AND $wpdb->p2p.p2p_from = '53' 
AND $wpdb->p2p.p2p_from = '126' 

---

実行されている完全なクエリ。結果は奇妙です

SELECT  SQL_CALC_FOUND_ROWS wp_posts., 
      wp_p2p. 
FROM  wp_posts 
INNER JOIN wp_p2p 
WHERE  1=1 
AND  wp_posts.post_type = 'news-articles' 
AND  ((
           wp_posts.post_status = 'publish')) 
AND  (
         wp_p2p.p2p_type = 'practice_areas_to_news_articles' 
      OR   wp_p2p.p2p_type = 'attorneys_to_news_articles') 
AND  wp_p2p.p2p_from IN 
      (
        SELECT t1.p2p_to 
        FROM  wp_p2p t1 
        LEFT JOIN wp_p2p t2 
        ON  t2.p2p_to = t1.p2p_to 
        AND  t2.p2p_from = '53' 
        WHERE  t1.p2p_from = '126') 
AND  wp_posts.id = wp_p2p.p2p_to 
ORDER BY wp_posts.post_date DESC 
LIMIT  0, 30
