ORDER BY子句在视图，内联函数，派生表，子查询和公用表表达式中无效，除非TOP，OFFSET或FOR XML是

Question

我的UPDATE声明在这里：

Update S 
set Status = 6 
Where Status = 5 
  and P_ID in (1, 3) 
  and ID in (Select dbo.T.sID 
             from dbo.T  
             Group By s 
             having Max(TDate) <= @t1 and Max(TDate) >= @t2 
                and sid is not null
             order by Max(TDate))

导致显示错误：

Msg 1033，Level 15，State 1，Line 6 除非还指定了TOP，OFFSET或FOR XML，否则ORDER BY子句在视图，内联函数，派生表，子查询和公用表表达式中无效。

Answer 1

order by条款对于内联查询毫无意义。只需从查询中删除order by Max(TDate)部分即可。

Update S 
set Status = 6 
Where Status = 5 
  and P_ID in (1, 3) 
  and ID in (Select dbo.T.sID 
             from dbo.T  
             Group By s 
             having Max(TDate) <= @t1 and Max(TDate) >= @t2 
                and sid is not null )
