嘿，我仍然掌握了一些查询和东西，所以请原谅所有常见的 sql 问题 8)

无论如何，我试图在某个值之后选择行。不明白？好的，这就是它的实际外观。

其中消息 id 为 9，在 uid_sent_deleted 列中的值为“1”。我试图在 uid_sent_deleted 列中最后一行的值为 '1' 之后选择行。

这是我目前正在使用的 sql。感谢您的帮助！

SELECT message_id, thread_id, messages.user_id, to_id, body, message_status, uid_sent_deleted
FROM messages
INNER JOIN messages_thread ON messages_thread.id = messages.thread_id
WHERE thread_id =1
GROUP BY messages.message_id
ORDER BY message_id ASC

【解决方案1】：

... WHERE thread_id = 1 AND id > 
     (SELECT MAX(id) FROM messages WHERE uid_sent_deleted = 1)

@Kenny 不应该在某处存在线程关联吗？

【解决方案2】：

SELECT message_id, thread_id, messages.user_id, to_id, body, message_status, uid_sent_deleted
FROM
    (SELECT thread_id t_id, MAX(message_id) m_id
     FROM messages
     WHERE thread_id =1 and uid_sent_deleted = 1
     GROUP BY thread_id) n
inner join messages on messages.message_id > n.m_id and messages.thread_id = n.t_id
INNER JOIN messages_thread ON messages_thread.id = messages.thread_id
ORDER BY message_id ASC
LIMIT 1

【解决方案3】：

子查询可能会起作用，您选择 MAX(message_id) WHERE uid_sent_deleted=1，然后加入...语法上有点模糊。
