Answer 1

あなたは、列Date_TimeとValue_Per_15minへのそれぞれの持つTagIDの最初の2つの値を選択したいと仮定すると、 。

SELECT [Date_Time],[1] TagID1,[2] TagID2,[Value_Per_15min] 
FROM 
(SELECT 
    [Date_Time], 
    [TagID], 
    [Value_Per_15min], 
    ROW_NUMBER()OVER(PARTITION BY [Date_Time],[Value_Per_15min] ORDER BY [TagID]) CNT 
FROM [RIDTL].[dbo].[Rawdata] 
WHERE Date_Time BETWEEN '01-09-2016 00:00:00:000' AND '2016-10-12 23:59:59:000')t 
PIVOT 
(MIN(TagID) 
FOR CNT IN ([1],[2]))piv;
