询问：

解释 SELECT SQL_CALC_FOUND_ROWS wp_posts.* FROM wp_posts 
内部连接 ​​wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) 
WHERE 1=1 AND ( wp_term_relationships.term_taxonomy_id IN (1,3,4,5) ) 
AND wp_posts.post_type = 'post' 
AND (wp_posts.post_status = 'publish' OR wp_posts.post_status = 'private') 
按 wp_posts.ID 分组 
ORDER BY wp_posts.post_date 
DESC 限制 0, 10;
