Probieren Sie so etwas aus:
DECLARE @myTable AS TABLE([ID] INT, [Field] VARCHAR(20), [Value] VARCHAR(20))
INSERT INTO @myTable VALUES ('1', 'year', '2011')
INSERT INTO @myTable VALUES ('1', 'month', 'August')
INSERT INTO @myTable VALUES ('2', 'year', '2009')
INSERT INTO @myTable VALUES ('1', 'day', '21')
INSERT INTO @myTable VALUES ('2', 'day', '31')
INSERT INTO @myTable VALUES ('2', 'month', 'July')
INSERT INTO @myTable VALUES ('3', 'year', '2010')
INSERT INTO @myTable VALUES ('3', 'month', 'January')
INSERT INTO @myTable VALUES ('3', 'day', NULL)
SELECT [ID], [year], [month], [day]
FROM
(
SELECT [ID], [Field], [Value] FROM @myTable
) t
PIVOT
(
MIN([Value]) FOR [Field] IN ([year], [month], [day])
) AS pvt
ORDER BY pvt.[year] DESC
Was zu folgenden Ergebnissen führen wird:
ID year month day
1 2011 August 21
3 2010 January NULL
2 2009 July 31
