这个是数据库写法，如果只需要hits的总和可以这样写，我是所有的都列出来了方便你学习这个是用来查询总的。SELECT( SELECT sum( hits ) FROM dr_1_book_extend WHERE cid = 104 ) as totalFROMdr_1_book AS aINNER JOIN dr_1_book_extend AS b ON b.cid = a.id WHEREb.cid = 104; 程序中你要写可以这样写查询汇总总数$total = \Phpcmf\Service::M()->db->query('SELECT ( SELECT sum( hits ) FROM dr_1_book_extend WHERE cid = 104 ) as total FROM dr_1_book AS a INNER JOIN dr_1_book_extend AS b ON b.cid = a.id WHERE b.cid = 104;')->getResultArray();这个是输出汇总的总数，这样就可以了，这两段代码就可以解决，104就是你那篇小说的id不是他下面的篇章的id，就是这个的id，代码都写好了，可以拿来直接用 echo $total[0]['total'];
