Ok, som du sa, du kommer att behöva dynamisk SQL, så gå först till denna länk . När du har läst det, prova följande:
UPPDATERAD KOD FÖLJANDE KOMMENTAR:
DECLARE @cols AS NVARCHAR(MAX), @cols2 AS NVARCHAR(MAX), @query AS NVARCHAR(MAX);
WITH CTE AS
(
SELECT *, CAST([Year] AS NVARCHAR(4))+RIGHT('00'+CAST([Month] AS NVARCHAR(2)),2) YearMonth
FROM YourTable
)
SELECT @cols = STUFF(( SELECT DISTINCT ',' + QUOTENAME(YearMonth)
FROM CTE
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,''),
@cols2 = STUFF(( SELECT DISTINCT ',ISNULL(' + QUOTENAME(YearMonth) + ',0) AS ' + QUOTENAME(YearMonth)
FROM CTE
FOR XML PATH(''), TYPE).value('.', 'NVARCHAR(MAX)'),1,1,'')
SET @query = '
SELECT Payroll, Forname, Surname, ' + @cols2 + '
FROM ( SELECT Payroll, Forname, Surname,
CAST([Year] AS NVARCHAR(4))+RIGHT(''00''+CAST([Month] AS NVARCHAR(2)),2) YearMonth,
Amount
FROM YourTable ) T
PIVOT(SUM(Amount) FOR YearMonth IN ('[email protected]+')) PT'
EXEC(@Query)
