SQL：ORDER BY日期

Question

我想訂購日期表，但我的查詢顯示錯誤：

The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.

我的查詢：

select intervaldate, [M1], [M2], [M3], [M4], [M5], [M6], [M7], [M8] 
    from 
    (select intervaldate,amount, name from (Select tSystem.Name, IntervalCount.IntervalDate, 
    sum(case when CounterName = 'Prod' then calculationUnits else 0 end) as Amount from IntervalCount, tsystem where 

    IntervalCount.intervaldate between '2017-03-06 00:00:00.000' and '2017-03-08 00:00:00.000' and IntervalCount.systemid =tsystem.id 

    group by tSystem.Name, IntervalCount.Intervaldate 
order by IntervalCount.Intervaldate asc 
    ) as T3) as T1 
    pivot 
    (sum (amount) 
    for name in ([M1], [M2], [M3], [M4], [M5], [M6], [M7], [M8]) 

    ) as t2 

我怎麼可以爲了通過IntervalDate？

由於消息錯誤說你不能在派生表中使用order by（在你的情況下）。 你應該是您使用哪種DBMS更換order by到查詢的末尾，如下

select intervaldate, [M1], [M2], [M3], [M4], [M5], [M6], [M7], [M8] 
    from 
    (select intervaldate,amount, name from (Select tSystem.Name, IntervalCount.IntervalDate, 
    sum(case when CounterName = 'Prod' then Units else 0 end) as Amount from IntervalCount, tsystem where 

    IntervalCount.intervaldate between '2017-03-06 00:00:00.000' and '2017-03-08 00:00:00.000' and IntervalCount.systemid =tsystem.id 

    group by tSystem.Name, IntervalCount.Intervaldate 
order by IntervalCount.Intervaldate asc 
    ) as T3) as T1 
    pivot 
    (sum (amount) 
    for name in ([M1], [M2], [M3], [M4], [M5], [M6], [M7], [M8]) 

    ) as t2 
    order by Intervaldate asc
