Question

所以我有以下查询，但我也需要帖子精选图片，你们可以帮我查询一下吗。

SELECT SQL_CALC_FOUND_ROWS wp_posts。* FROM wp_posts，wp_term_relationships，wp_terms WHERE wp_posts.ID = wp_term_relationships.object_id和wp_posts.post_status ='发布' AND wp_terms.term_id = wp_term_relationships.term_taxonomy_id GROUP BY wp_posts.ID ORDER BY wp_posts.post_date DESC LIMIT 0,100

我最近不得不使用精选图片检索最新的4个帖子，发现它真的很难。这段代码对我有用（最后）我知道它可能不准确，但不可能在评论中发帖，我相信它会有所帮助：

SELECT title, name, date, content, CONCAT(LEFT(image, LENGTH(image) - LOCATE('.', REVERSE(image))),'-768x576.',SUBSTRING_INDEX(image, '.', -1)) AS image
            FROM (
             SELECT    
             p.post_title AS title, 
             p.post_status AS 'status', 
             p.post_date AS date,
             p.post_content AS content,
             p.post_name AS name,
             (SELECT `guid` FROM wp_posts WHERE id = m.meta_value) AS image
             FROM wp_posts p, wp_postmeta m
             WHERE p.post_type = 'post'
             AND p.post_status = 'publish'
             AND p.id = m.post_id
             AND m.meta_key = '_thumbnail_id'
             LIMIT 4
            ) TT
