選擇有MAX日期的行

Question

我想選擇具有最新日期的ROW。我似乎無法選擇ID和發佈。

T.Released = MAX（T.Released）不適用於我。我正在使用MS SQL

SELECT ID , Released 
FROM (SELECT [id] 
     ,[Released]  
    FROM [dbo].[PressReleases] 
    where id in 
    (
     ..... 
    )) as T 

Where T.Released = MAX (T.Released) 

id Released 
3 2016-05-26 19:30:41.100 
214 2016-07-04 10:10:32.500 
244 2017-01-20 12:20:29.900 
247 2017-03-09 15:50:38.600 
235 2017-06-01 18:10:38.900 
237 NULL 

Answer 1

只需在子查詢中選擇MAX Released-Date即可。

SELECT [id] 
     ,[Released]  
    FROM [dbo].[PressReleases] 
WHERE Released = ( 
        SELECT MAX(Released) 
         FROM [dbo].[PressReleases] 
         -- Select here your T Table with the Where Conditions 
       ) 

Answer 2

您必須在子查詢中有該列;

SELECT ID , Released 
FROM (SELECT [id] 
     ,[Released]  
    FROM [dbo].[PressReleases] 
    where id in 
    (
     ..... 
    )) as T  
Where T.Released = MAX (T.Released) 

或者你也可以做;

SELECT ID , Released 
FROM [dbo].[PressReleases] 
    where id in 
    (
     ..... 
    ) 
AND T.Released = (SELECT MAX (Released) FROM dbo.PressReleases)
