我需要最后一个ops_status，即ARCHIVED，当它被更新时，即＆＃34; 2017-04-06＆＃34; - 所以上面数据中的"32307107 ARCHIVED 2017-04-06"行。有人可以帮帮我吗。

Answer 1

select bug_id, ops_status, max(partition_date)
 from table1
 where ops_status = 'ARCHIVED'
 group by bug_id,ops_status

这是在SQL-Server

中

Answer 2

如果我理解正确，您需要第一个状态更改为＆＃34;已存档＆＃34;对于bug_id。为此，您可以使用子查询来获取未归档的最新日期。在主查询中，您可以使用MIN查找最早的存档日期。

SELECT bug_id, ops_status, MIN(partition_date)
FROM yourTable AS a
WHERE a.partition_date > 
    (SELECT MAX(partition_date)
    FROM yourTable AS b
    WHERE b.status = 'PREPUBLISH'
      AND a.bug_id = b.bug_id)

需要SQL查询以下内容：
