SQL：ORDER BY日期

Question

我想订购日期表，但我的查询显示错误：

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.

我的查询：

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 

我怎么可以为了通过IntervalDate？

由于消息错误说你不能在派生表中使用order by（在你的情况下）。 你应该是您使用哪种DBMS更换order by到查询的末尾，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
