这可能对你有帮助

declare @sDate datetime,
        @eDate datetime
select  @sDate = '2013-02-21',
        @eDate = '2013-04-25'
;WITH CTE_TEST AS (
    SELECT @sDate SDATE,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@sDate)+1,0)) EDATE
    UNION ALL
    SELECT  EDATE+1,DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,DATEADD(MONTH,1,SDATE))+1,0))
    FROM    CTE_TEST C WHERE DATEADD(MONTH,1,SDATE) < DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,@eDate)+1,0))
)   
SELECT DATENAME(MONTH,SDATE) MNAME,SDATE,(CASE WHEN EDATE > @eDate THEN @eDate ELSE EDATE END) EDATE FROM CTE_TEST
