对数据库进行sql操作前,请先对数据库进行备份,一定要有备份数据的好习惯！

先检查下数据是否一致,将以下命令中的47替换成你准备删除文章所在分类的ID

SELECT * FROM `wp_posts`,`wp_term_relationships` WHERE wp_posts.ID = wp_term_relationships.object_id AND wp_term_relationships.term_taxonomy_id = 128;

然后进行删除

DELETE `wp_posts` FROM `wp_posts`, `wp_term_relationships` WHERE wp_posts.ID = wp_term_relationships.object_id AND wp_term_relationships.term_taxonomy_id = 128
