probeer:
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
uitgang:

het werkt met meerdere rijen in de tabel, zie hier:
DECLARE @YourTable table (YourDate datetime, ValueOf int)
insert into @YourTable VALUES ('2011-7-12',5)
insert into @YourTable VALUES ('2012-4-24',6)
;WITH AllNumbers AS
(
SELECT 0 AS Number
UNION ALL
SELECT Number+1
FROM AllNumbers
WHERE Number<4
)
SELECT
y.ValueOf
,dateadd(month,number,DATEADD(month,DATEDIFF(month,0,y.YourDate),0))
FROM @YourTable y
INNER JOIN AllNumbers a ON 1=1
ORDER BY 1,2

Ik heb ook geen SQL Server 2008 beschikbaar, dus ik heb datetime gebruikt, als je 2008 hebt, kun je DATE
gebruiken datatype en je hoeft de datetime niet te verlagen, dus gebruik deze regel:
dateadd(month,number,y.YourDate)
