Merge Start And End Columns To One Column

Question

I have searched high and low for weeks now trying to find a solution to my problem.

My problem is as follows:

A have a table with start and end co-ordinates and dates from a vehicle telemetry provider.

I need to merge these into one column in order for our reporting solution to be able to plot them.

Some example data is as follows:

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)

Any ideas / code will be greatly received.

Answer 1

By using below you can get the desired results. You can use Cross apply with values clause.

     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) 

Answer 2

the Query uses union like below

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
