SQL语句显示两个日期

Question

我有四个变量CurrentMonth，CurrentYear，一个月，一年之间既月份和年份。我想要一个SQL语句显示（Month，Year）到（currentMonth，CurrentYear）之间的所有月份和年份。下面显示的月份，但我需要几个月和一年，我没有日期，但只有开始和结束的月和年。

DECLARE @StartDate DATETIME, 
     @EndDate DATETIME; 

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'   
AND  x.number <= DATEDIFF(MONTH, @StartDate, @EndDate); 

Answer 1

这是对上一个答案的修改，以满足您的月/年需求。

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);
