ORDER BY子句在视图，内联函数，派生表无效，子查询

Question

我的存储procedeur这样的：

alter PROCEDURE [dbo].[ParkingDeatailsReportnewstack] 
     @startdate NVARCHAR(100), 
     @enddate NVARCHAR(100)AS 
BEGIN 
    DECLARE @cols AS NVARCHAR(MAX) , @query AS NVARCHAR(MAX) 

    SELECT @cols = STUFF(( SELECT DISTINCT ',' + QUOTENAME(Vtype) 
    FROM dbo.VType_tbl FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'), 1, 1, '') 

    SET @query = 
     'SELECT LocName,Date, ' + @cols + ' 
     from ( 
       select l.LocName,v.Vtype, convert(date, dtime) as Date 
       from Transaction_tbl t 
       join VType_tbl v on t.vtid = v.vtid 
       join dbo.Location_tbl l on t.locid=l.Locid 
       where dtime between ''' + @startdate + ''' and ''' + @enddate + ''' order by l.LocName 
     ) d 
     pivot (
       count(Vtype) for Vtype in (' + @cols + ') 
     ) p ' 

    EXEC sys.sp_executesql @query 
End 

我想我的升序LOCNAME但同时也让 为了通过l.LocName收到错误：ORDER BY子句在视图，内联函数，派生表无效，子查询

Answer 1

试试你的order by条款迁移到最 select语句—其中order by使任何唯一的地方感。

喜欢的东西

select LocName , 
     ... 
from ... 
order by LocName 

甚至更​​简单，封装了原始的，复杂的select在外部选择，其唯一目的是订货，沿着这些线路：

select * 
from (select 
     ... 
    ) t 
order by t.x, t.y , ...

我们可以解决这个问题很容易通过在视图定义中添加一个TOP 100 PERCENT子句。 尝试使用这种方式 - http://www.sqlpassion.at/archive/2015/05/25/the-ambiguity-of-the-order-by-in-sql-server/
