Dynamisch draaien met datum als kolom

Hier is je voorbeeldtabel

SELECT * INTO #Names
FROM
(
SELECT 1 ID,'ITEM1' NAME 
UNION ALL
SELECT 2 ID,'ITEM2' NAME 
)TAB

SELECT * INTO #Stockdates
FROM
(      
SELECT 1 ID,1 NAMEID,8 STOCK,'2-1-2014 ' [DATE]
UNION ALL
SELECT 2 ID,2 NAMEID,2 STOCK,'4-1-2014 ' [DATE]
)TAB

Zet de join-gegevens in een tijdelijke tabel

SELECT N.NAME,S.[DATE],S.STOCK 
INTO #TABLE
FROM #NAMES N
JOIN #Stockdates S ON N.ID=S.NAMEID

Verkrijg de kolommen voor pivot

DECLARE @cols NVARCHAR (MAX)

SELECT @cols = COALESCE (@cols + ',[' + CONVERT(NVARCHAR, [DATE], 106) + ']', 
               '[' + CONVERT(NVARCHAR, [DATE], 106) + ']')
               FROM    (SELECT DISTINCT [DATE] FROM #TABLE) PV  
               ORDER BY [DATE]

Draai het nu

DECLARE @query NVARCHAR(MAX)
SET @query = '           
              SELECT * FROM 
             (
                 SELECT * FROM #TABLE
             ) x
             PIVOT 
             (
                 SUM(STOCK)
                 FOR [DATE] IN (' + @cols + ')
            ) p      

            '     
EXEC SP_EXECUTESQL @query

En je resultaat is hier
