Question

我存储的程序如下：

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

我希望按升序排列我的locname但是在给予时 l.LocName获取错误的顺序：ORDER BY子句在视图，内联函数，派生表，子查询中无效

Answer 1

我们可以通过在视图定义中添加 TOP 100 PERCENT 子句来轻松解决问题。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/

Answer 2

尝试将order by子句迁移到最外层选择语句中 - order by唯一有意义的地方。

像

这样的东西

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

或者，甚至更简单，将原始的复杂select包装在外部选择中，其唯一目的是按顺序排列：

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

ORDER BY子句在视图，内联函数，派生表，子查询中无效
