僅從特定表中選擇maxdate行

Question

在這個查詢中我有表tProtocol (azdp) ，它有屬性： ProtocolID （主鍵）， ObjectID （文檔的ID）和Date 。 問題是，每個ObjectID可能有許多日期值。 我想選擇按ObjectID分組的max(Date)行。

我在where子句中試過這個

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

它返回錯誤：

當未使用EXISTS引入子查詢時，只能在選擇列表中指定一個表達式。

我如何用存在來寫它？

這是完整的查詢（只是為了查看它是什么類型的查詢，甚至不嘗試運行它）
