將開始和結束列合併到一列

我已經搜索了幾個星期的高和低，現在試圖找到我的問題的解決方案。將開始和結束列合併到一列

我的問題是：

一個具有從車輛遙測提供起點和終點座標和日期表。

我需要將這些合併到一個列中，以便我們的報告解決方案能夠繪製它們。

一些示例數據如下：

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/代碼會大受歡迎。

感謝，

提示：如果您想創建兩倍多行，請使用CROSS JOIN對着兩行的表格。然後，只需使用case語句來選擇哪些列進入哪些行。 –

正在考慮CTE會是一個更有效的方式。將困惑你的提示併發布我的發現。謝謝！ –

你有兩個可以選擇:)。這是一個高質量的問題 - 使得發佈設置腳本的努力使得構建解決方案變得更容易！ –

通過使用下面你可以得到想要的結果。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)

真棒我喜歡它。 –

@ Nick.McDermaid謝謝:) – Buddi

完美的作品，非常優雅！從來沒有見過這樣做，並且一定會在未來使用這種方法！ –

我認爲這是你以後：

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

查詢使用工會像下面

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

請使用代碼標籤並格式化查詢以獲得更好的可讀性。 – Seb
