訂購SQL Server中的條款更新詢問

Question

我需要在SQL Server中使用ORDER BY子句2008例如

Update tblTempChek Set TmpCheckIn='15:50:03' 
Where TempID IN (
    Select TempID 
    From tblTempChek 
    Where convert(date, TmpDate)='2015-06-23' AND UserID='1' 
    Order By TempID Desc 
) 

更新表，但是這給了錯誤

Msg 1033, Level 15, State 1, Line 3 
    The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP or FOR XML is also specified. 

Answer 1

你需要使用TOP：

Update tblTempChek Set TmpCheckIn='15:50:03' 
    Where TempID in (
     Select TOP 1 TempID 
     From tblTempChek 
     Where Convert(date, TmpDate)='2015-06-23' AND UserID='1' 
     Order By TempID Desc 
    ) 

Answer 2

一種替代可以使用max，如：

Update tblTempChek Set TmpCheckIn='15:50:03' 
Where TempID IN (
    Select MAX(TempID) 
    From tblTempChek 
    Where convert(date, TmpDate)='2015-06-23' AND UserID='1' 
) 

此假設TempID是一些遞增值。
