将开始和结束列合并到一列

问题描述：

我已经搜索了几个星期的高和低，现在试图找到我的问题的解决方案。将开始和结束列合并到一列

我的问题是：

一个具有从车辆遥测提供起点和终点坐标和日期表。

我需要将这些合并到一个列中，以便我们的报告解决方案能够绘制它们。

一些示例数据如下：

DECLARE @TblVar AS TABLE([ServiceID] INT 
        ,[StartDate] DATETIME 
        ,[StartLocation] VARCHAR(255) 
        ,[StartLat] FLOAT 
        ,[StartLong] FLOAT 
        ,[EndDate] DATETIME 
        ,[EndLocation] VARCHAR(255) 
        ,[EndLat] FLOAT 
        ,[EndLong] FLOAT); 
INSERT INTO @TblVar 

VALUES (48322, '2016-11-28 05:38:37.000','Weaver Road,Leicester',52.5753273,-1.306842,'2016-11-28 05:40:02.000','Earl Street,Leicester',52.5781,-1.3048711)

任何想法/代码会大受欢迎。

感谢，

提示：如果您想创建两倍多行，请使用CROSS JOIN对着两行的表格。然后，只需使用case语句来选择哪些列进入哪些行。 –

正在考虑CTE会是一个更有效的方式。将困惑你的提示并发布我的发现。谢谢！ –

你有两个可以选择:)。这是一个高质量的问题 - 使得发布设置脚本的努力使得构建解决方案变得更容易！ –

答

通过使用下面你可以得到想要的结果。您可以使用Cross apply with value子句。

 SELECT A.SERVICEID, 
     ROW_NUMBER() OVER(PARTITION BY A.SERVICEID ORDER BY A.SERVICEID) AS PATHORDER, 
     B.* 
FROM @TBLVAR A 
     CROSS APPLY(
     VALUES 
       ([STARTDATE],[STARTLOCATION],[STARTLAT],[STARTLONG]), 
       ([ENDDATE],[ENDLOCATION],[ENDLAT],[ENDLONG]) 
      )B(DATE, LOCATION, LATTITUDE, LONGITUD)

真棒我喜欢它。 –

@ Nick.McDermaid谢谢:) – Buddi

完美的作品，非常优雅！从来没有见过这样做，并且一定会在未来使用这种方法！ –

答

我认为这是你以后：

SELECT 
ServiceID, 
DENSE_RANK() OVER(
      PARTITION BY ServiceID 
      ORDER BY CASE WHEN CJ.R=1 THEN [StartDate] ELSE EndDate END) PathOrder, 
CASE WHEN CJ.R=1 THEN [StartDate] ELSE EndDate END [Date], 
CASE WHEN CJ.R=1 THEN [StartLocation] ELSE [EndLocation] END [Location], 
CASE WHEN CJ.R=1 THEN [StartLat] ELSE [EndLat] END [Lat], 
CASE WHEN CJ.R=1 THEN [StartLong] ELSE [EndLong] END [Long] 
FROM @TblVar 
CROSS JOIN 
(SELECT 1 As R UNION ALL SELECT 2) CJ

答

查询使用工会像下面

SELECT ServiceID, ROW_NUMBER() over (order by StartDate) AS PathOrder, StartDate AS Date, StartLocation AS Location, StartLat AS Lattitude, StartLong AS Longitude 
FROM (SELECT ServiceID, StartDate, StartLocation, StartLat, StartLong 
FROM @TblVar 
UNION ALL 
SELECT ServiceID, EndDate, EndLocation, EndLat, EndLong 
FROM TblVar AS @TblVar_1) AS q1

请使用代码标签并格式化查询以获得更好的可读性。 – Seb

将开始和结束列合并到一列
