转换分隔符

Question

我正在使用 SQL Server Express 2005，我想转换列和小数分隔符：

Use StockDataFromSella;
DECLARE @D1 DateTime 
DECLARE @D2 DateTime 
DECLARE @Interval FLOAT 

SET @D1  = '2009-09-21T09:00:00.000' 
SET @D2  = '2010-10-20T17:30:00.000'
SET @Interval = 15 

;WITH  
L0 AS (SELECT 1 AS c UNION ALL SELECT 1), 
L1 AS (SELECT 1 AS c FROM L0 A CROSS JOIN L0 B), 
L2 AS (SELECT 1 AS c FROM L1 A CROSS JOIN L1 B), 
L3 AS (SELECT 1 AS c FROM L2 A CROSS JOIN L2 B), 
L4 AS (SELECT 1 AS c FROM L3 A CROSS JOIN L3 B), 
Nums AS (SELECT ROW_NUMBER() OVER (ORDER BY (SELECT 0)) AS i FROM L4), 
Ranges AS( 
SELECT  
      DATEADD(MINUTE,@Interval*(i-1),@D1) AS StartRange, 
      DATEADD(MINUTE,@Interval*i,@D1) AS NextRange 
FROM Nums where i <= 1+CEILING(DATEDIFF(MINUTE,@D1,@D2)/@Interval)) 
,cte AS ( 
SELECT  
     *  
     ,ROW_NUMBER() OVER (PARTITION BY Simbolo,r.StartRange ORDER BY [DataOra])      AS RN_ASC  
     ,ROW_NUMBER() OVER (PARTITION BY Simbolo,r.StartRange ORDER BY [DataOra] DESC) AS RN_DESC 
FROM Ranges r 
JOIN dbo.tbl1MinENI p  ON p.[DataOra] >= r.StartRange and p.[DataOra] < r.NextRange ) 
SELECT  

      CONVERT(VARCHAR, MAX(CASE WHEN RN_ASC=1 THEN [DataOra] END), 103) AS DataOraDate, 
      CONVERT(CHAR(5), MAX(CASE WHEN RN_ASC=1 THEN [DataOra] END), 108) AS DataOraTime,     
      MAX(CASE WHEN RN_ASC=1 THEN [DataOra] END) AS DataOra, 
      MAX(CASE WHEN RN_ASC=1 THEN [Apertura] END) AS [Apertura], 
      MAX(Massimo) Massimo, 
      MIN(Minimo)  Minimo, 
      MAX(CASE WHEN RN_DESC=1 THEN [Chiusura] END) AS [Chiusura],
      SUM(Volume) Volume
      /*MAX(CASE WHEN RN_DESC=1 THEN [DataOra] END) AS ChiusuraDataOra*/
FROM cte 
GROUP BY Simbolo,StartRange
ORDER BY DataOra

执行查询时，复制并粘贴到 txt 文件中将给出“;”作为列分隔符，而我需要 ','，并且我在需要 '.' 的地方得到 ',' 作为小数。

还有一种方法可以删除 DataOraTime 列中的“：”吗？

谢谢！阿尔贝托

结果的复制和粘贴与查询无关，而是与执行查询的程序有关，因为该程序负责将结果格式化为可以复制到剪贴板的格式。

要更改日期和时间格式，您很可能会在执行语句之前更改一些会话变量。
