zkuste:
DECLARE @YourTable table (YourDate datetime, value int)
insert into @YourTable VALUES ('2011-7-12',5)
;WITH AllNumbers AS
(
SELECT 0 AS Number
UNION ALL
SELECT Number+1
FROM AllNumbers
WHERE Number<4
)
SELECT
dateadd(month,number,DATEADD(month,DATEDIFF(month,0,YourDate),0))
FROM @YourTable y
INNER JOIN AllNumbers a ON 1=1
výstup:

Také nemám k dispozici SQL Server 2008, takže jsem použil datum a čas, pokud máte 2008, můžete použít DATE
datový typ a nemusíte zadávat datum a čas, takže použijte tento řádek:
dateadd(month,number,y.YourDate)
