僅從特定表中選擇maxdate行

Question

在此查詢中，我具有表tProtocol (azdp)，它具有屬性：ProtocolID（主鍵），ObjectID（文檔的ID）和Date。問題是，每個ObjectID可能有很多日期值。我想選max(Date)行，按ObjectID分組。

Only one expression can be specified in the select list when the subquery is not introduced with EXISTS.

如何我存在寫：

我在where子句

and azdp.Date = (select max(Date), ObjectID from tProtocol group by ObjectID) 

它返回的錯誤嘗試這樣做？

下面是完整的查詢（只是看到什麼樣的查詢是它，甚至不嘗試運行它）

select row_number() over (partition by objectid order by date desc) rn, 
+ the rest of your very long query 
) 
select * from x where rn = 1
