Question

我正在制作一个数据透视表，其中包含顶部的日期，旁边的客户以及中间的销售数据。作为其中的一部分，我从临时表#FileDates获取我的IN子句。以下是用于获取最旧到最新顺序的日期的代码。我想从最新到最旧的订单中获取它。

SELECT * INTO #FileDates
FROM
    ( SELECT distinct DLDate [DATE] from Daily where DLDate between @begin31 and @end  )   TAB;

接下来是：

DECLARE @cols NVARCHAR (MAX)

SELECT @cols = COALESCE (@cols + ',[' + CONVERT(NVARCHAR, [DATE], 106) + ']', 
           '[' + CONVERT(NVARCHAR, [DATE], 106) + ']')
           FROM    (SELECT DISTINCT [DATE] FROM #FileDates ) PV

我试图在我的子查询中放置一个order by子句但是它没有用，因为你不能在内联SQL中有顺序。我试着把它改写成：

SELECT distinct DLDate [DATE] into #FileDates 
from Daily where DLDate between @begin31 and @end  order by Date desc

执行命令但日期不正确。请帮忙。

Answer 1

如果您有TOP，您可以使用订单。我不认为你会有1000万行。

SELECT * INTO #FileDates
FROM (
   SELECT distinct TOP 999999999 DLDate [DATE]
   from Daily
   where DLDate between @begin31 and @end
   ORDER BY DLDate DESC
)   TAB;

但是，如果显式声明临时表，这就是我写它的方式。

INSERT INTO #FileDates
   SELECT distinct DLDate [DATE]
   from Daily
   where DLDate between @begin31 and @end
   ORDER BY DLDate DESC

我接受了Ghost的建议并在出路时订购了所以我的列的选择代码现在是：

SELECT @cols = COALESCE (@cols + ',[' + CONVERT(NVARCHAR, [DATE], 106) + ']', 
       '[' + CONVERT(NVARCHAR, [DATE], 106) + ']')
       FROM    (SELECT DISTINCT [DATE] FROM #FileDates ) PV   order by [DATE] desc

SQL查询日期排序顺序不起作用
