Mysql UNION on wordpress

Question

我需要帮助来开发wordpress定制。我有以下MySQL查询与UNION指令：

SELECT 
    wp_posts.* 
FROM wp_posts 
    INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) 
    LEFT JOIN wp_postmeta ON (wp_posts.ID = wp_postmeta.post_id) 
    LEFT JOIN wp_postmeta AS mt1 ON (wp_posts.ID = mt1.post_id AND mt1.meta_key = 'dir_featured') 
WHERE 
    (wp_term_relationships.term_taxonomy_id IN (2151)) AND 
    wp_posts.post_type = 'ait-dir-item' AND 
    ((wp_posts.post_status = 'publish')) AND 
    ( 
     ( 
     wp_postmeta.meta_key = 'dir_featured' AND 
     CAST(wp_postmeta.meta_value AS CHAR) = 'yes' 
     ) 
    ) 
GROUP BY wp_posts.ID 
UNION 
SELECT 
    wp_posts.* 
FROM wp_posts 
    INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) 
    LEFT JOIN wp_postmeta ON (wp_posts.ID = wp_postmeta.post_id) 
    LEFT JOIN wp_postmeta AS mt1 ON (wp_posts.ID = mt1.post_id AND mt1.meta_key = 'dir_featured') 
WHERE 
    wp_term_relationships.term_taxonomy_id IN (2151) AND 
    wp_posts.post_type = 'ait-dir-item' AND 
    wp_posts.post_status = 'publish' AND 
    mt1.post_id IS NULL 
GROUP BY wp_posts.ID 

我想把这个查询与WordPress参数转化。可能吗？

这个查询的目的是什么？ 这是你在Wordpress模式下的查询

$args = array(
    'cat'   => 2151, 
    'post_type'  => 'ait-dir-item', 
    'post_status' => 'publish', 
    'meta_query'  => array(
       array(
        'key'  => 'dir_featured', 
        'value' => 'yes', 
        'compare' => '==', 
       ), 
      ), 

); 
query_posts($args);
