这是我的模态查询
SELECT COUNT(IF(n.status='0',1, NULL)) as counter, n.notify_from, n.notify_to, n.status, n.notify_text, n.notify_id, n.notify_type, n.notify_time, r.user_name, r.user_image, r.user_gender FROM `notifications` AS n JOIN register r ON n.`notify_from` = r.unique_user_name WHERE n.`notify_to` = 'IzaazG' AND n.`notify_type` = '6' GROUP BY n.`notify_from` ORDER BY n.`notify_id` DESC
从此查询中，我无法从通知表中获取最后一条记录。
答案 0 :(得分：0)
从功能COUNT中删除IF条件 并尝试使用case语句
