SQL 显示两个日期之间的月份和年份

问题描述

我有四个变量 CurrentMonth、CurrentYear、Month、year.我想要一个 SQL 语句，它显示 (Month,Year) 到 (currentMonth,CurrentYear) 之间的所有月份和年份.下面显示月份，但我需要月份和年份，我没有日期，但只有开始和结束的月份和年份.

I have four variables CurrentMonth, CurrentYear, Month, year. I want to have a SQL statement which displays all the months and years between (Month,Year) to (currentMonth,CurrentYear). The below displays months but I need months and year and I dont have dates but only month and year of start and End.

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);

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);
