Question

我有一个问题是创建一个SQL查询请求。我有一个工作查询，以获取类别和自定义帖子类型和meta_key地图坐标＆＃39;在我的user_id上的wp_usermeta表中。我尝试完成的是扩展查询，我还从我的wp_usermeta表中使用meta_key＆＃39; some_value＆＃39;获得另一个meta_value。所以我需要搜索两个meta_keys值（mapcoordinates，somevalue）而不是一个（mapcoordinates），参见工作示例也许有人可以帮助我

SELECT SQL_CALC_FOUND_ROWS  wp_posts.ID, wp_usermeta.meta_value AS user_map_coord, wp_usermeta.user_id
        FROM wp_posts  
        INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id)
        INNER JOIN wp_usermeta  ON ( wp_posts.post_author = wp_usermeta.user_id )
        WHERE 1=1
        AND ( wp_term_relationships.term_taxonomy_id IN (5,6))
        AND  wp_posts.post_type = 'ouder_type'
        AND wp_usermeta.meta_key= 'mapcoordinates'
        AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private') 
        GROUP BY wp_posts.ID ORDER BY wp_posts.post_date

以上查询正在运行。我喜欢用这样的东西扩展它。

SELECT SQL_CALC_FOUND_ROWS  wp_posts.ID, wp_usermeta.meta_value AS user_map_coord, wp_usermeta.user_id
        FROM wp_posts  
        INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id)
        INNER JOIN wp_usermeta  ON ( wp_posts.post_author = wp_usermeta.user_id )
        WHERE 1=1
        AND ( wp_term_relationships.term_taxonomy_id IN ( 5,6))
        AND  wp_posts.post_type = 'ouder_type'
        AND wp_usermeta.meta_key= 'mapcoordinates'
        // this line added not working i get only one result , expecting 2 results
        AND wp_usermeta.meta_key= 'somevalue'
        AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private') 
        GROUP BY wp_posts.ID ORDER BY wp_posts.post_date

你有wp_usermeta.meta_key同时等于两个不同的东西，所以可能不应该得到任何结果。我想你所追求的更多的是：

AND wp_usermeta.meta_key IN（'mapcoordinates'，'somevalue'）
