The below displays months but I need months and year and I dont have dates but only month and year of start and End.

SELECT @StartDate = '20110501'
,@EndDate = '20110801';
SELECT DATENAME(MONTH, DATEADD(MONTH, x.number, @StartDate)) AS MonthName
FROM master.dbo.spt_values x
WHERE x.type = 'P'

推荐答案
这是对上一个回答的修改,来自 indicently 以满足您的月/年需求.
This is a modification from the previous answer from indicently to meet your Month/Year needs.
DECLARE @FromMonth varchar(2), @FromYear varchar(4), @ToMonth as Varchar(2), @ToYear as varchar(4)
SET @FromMonth = '01';
SET @FromYear = '1944';
SET @ToMonth = '04';
SET @ToYear = '1956';
DECLARE @DateFrom smalldatetime, @DateTo smalldatetime;
SET @DateFrom=@FromYear+@FromMonth+'01';
SET @DateTo=@ToYear+@ToMonth+'01';
-------------------------------
WITH T(date)
AS
(
SELECT @DateFrom
UNION ALL
SELECT DateAdd(month,1,T.date) FROM T WHERE T.date < @DateTo
)
SELECT datename(m,date) + '-' + datename(yy,date) as DN FROM T
OPTION (MAXRECURSION 32767);
