sql - MSSQL - 选择表中最新出现的几行

Question

所以，我正在用头撞墙……我有一个表(有几百万行)，看起来像这样:

ID  Time            Area    Name
1   2017-01-01 01:42    21  Test
1   2017-01-02 02:13    21  Test
1   2017-02-01 12:45    30  N/A
1   2017-03-12 02:23    41  N/A
2   2017-02-15 04:25    20  N/A

我想运行一个查询来选择某个 ID 的最新出现的区域；结果是这样的:

ID  Time            Area    Name
1   2017-01-02 02:13    21  Test
1   2017-02-01 12:45    30  N/A
1   2017-03-12 02:23    41  N/A

select max(Time),
"of every area"
from TABLE
where ID = 1

如果有人能给我线索，那就太棒了!

Answer 1

另一个选项(无子查询和/或额外字段)

示例

 Select Top 1 with Ties *
  From  YourTable
  Where ID =1
  Order By Row_Number() over (Partition By Area Order By [Time] Desc)

返回

ID  Time                     Area   Name
1   2017-01-02 02:13:00.000  21     Test
1   2017-02-01 12:45:00.000  30     N/A
1   2017-03-12 02:23:00.000  41     N/A
