我已经搜索了好几个星期，现在试图找到解决问题的方法。
我的问题如下：
A有一张表，上面有车辆遥测提供者的起点和终点坐标和日期。
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：
s <- function(...){
sum(..., na.rm = TRUE)
}
看起来像这样：
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)

通过使用以下内容，您可以获得所需的结果。您可以使用Cross apply with values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)
答案 1 :(得分：1)
Query使用如下所示的联合
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
答案 2 :(得分：0)
我认为这就是你所追求的：
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
