假设我有一张这样的表：
表帐户
id | username
1 | myuser123
2 | secretuser
表订阅
id | username | subsStartDate | subsEndDate
1 | myuser123 | 2017-01-19 | 2017-02-19
2 | secretuser| 2017-01-19 | 2017-02-19
3 | myuser123 | 2017-02-19 | 2017-03-19
4 | secretuser| 2017-02-19 | 2017-03-19
如何获取table中每个用户的最新 subsEndDate信息。我正在寻找与此类似的输出：account
输出寻找
id | username | subsStartDate | subsEndDate
3 | myuser123 | 2017-02-19 | 2017-03-19
4 | secretuser| 2017-02-19 | 2017-03-19
像这样的事情：
SELECT s.id, s.username, s.subsStartDate, endate as subsEndDate
FROM
subscription s
INNER JOIN
(SELECT id, Max(subsEndDate) as endate
FROM subscription
GROUP BY id) t ON t.id = s.id
