我想要每个月的最后一天,所以我写了这样的查询

declare @date datetime set @date='31-jan-2012' 
while @date<='31-Dec-2012' 
  Begin 
    print @date 
    set @date= DATEADD(M,1,@date)
  End

但我得到了像

Jan 31 2012 12:00AM
Feb 29 2012 12:00AM
Mar 29 2012 12:00AM
Apr 29 2012 12:00AM
May 29 2012 12:00AM
Jun 29 2012 12:00AM
Jul 29 2012 12:00AM
Aug 29 2012 12:00AM
Sep 29 2012 12:00AM
Oct 29 2012 12:00AM
Nov 29 2012 12:00AM
Dec 29 2012 12:00AM

你可能会更好: -

declare @date datetime;
declare @lastDay datetime;

-- Start on the first day of the next month
-- This'll ensure that your month add doesn't throw 
-- weird results
set @date='01-Feb-2012'
while @date<='01-Jan-2013'

Begin
    -- Get last day of previous month
    set @lastDay = DATEADD(DAY, -1, @date)

    -- print that
    print @lastDay

    -- increment @date to move one month into the future.
    set @date= DATEADD(month,1,@date)
End

您没有指定正在使用的 SQL Server 版本。

如果您在SQL Server 2012,您可以使用该EOMONTH()功能。

大家都说了这么多之后,更新来了:

Declare @FromDate   DateTime
;

Select  @FromDate   =   Convert(DateTime, '2012-1-1')
;

With    CTE (
    Level
,   FirstDayOfMonth
,   Value
)   As  (
    Select  1       As  Level
    ,   @FromDate
    ,   DateAdd(Day, -1, DateAdd(Month, 1, @FromDate))
Union   All
    Select  Level
    +   1
    ,   FirstDayOfMonth
,   DateAdd(Day, -1, DateAdd(Month, Level + 1, FirstDayOfMonth))
        From    CTE
        Where   Level   <   12
)   Select  Value
        From    CTE
        Order   By  Value

这是一个CTE(通用表表达式)。第一个值应该是第二个月的第一天,加上 -1 天后它将是一月的最后一天。当然,它会给你结果。

我所做的只是使用DateAdd(Day, -1, [下个月的第一天]),就这么简单!

只是为了好玩,这样,我确实从二月的第一天开始,让引擎检测到一月的最后一天!:D 也许明年在另一个桑迪的表亲风暴地球改变了它的方式之后,一月不再是 31 天了!所以你的代码将工作......

谢谢大家让我更新这个答案。

希望能帮助到你。

或者你可以试试:

Declare @Month Integer
Set @Month = 1
While @Month <= 12
Begin
  Print DATEADD(s,-1,DATEADD(mm, DATEDIFF(m,0,GETDATE())+@Month,0))
  Set @Month = @Month+1
End

使用以下功能可以通过此查询来实现您想要的:-

DECLARE @StartDate DATETIME SET @StartDate = '2012-01-31'
DECLARE @EndDate DATETIME SET @EndDate = '2012-12-31'

SELECT DISTINCT dbo.F_TABLE_DATE.END_OF_MONTH_DATE FROM dbo.F_TABLE_DATE(@StartDate, @EndDate)

这是我多年前发现的一个日期函数,至今仍在使用,它包含与您可能想要的日​​期有关的所有内容。

create function [dbo].[F_TABLE_DATE]
(
    @FIRST_DATE     datetime,
    @LAST_DATE      datetime

尝试:

with cte as
(select convert(date, '2012-01-31', 102) lastdate
 union all
 select dateadd(d,-1,dateadd(m,1,(dateadd(d,1,lastdate))))
 from cte where lastdate < '2012-12-31')
select * from cte

如果你有一个数字表(*),它只是:

select DATEADD(month,n,'20120131') from Numbers where n between 0 and all

基本上,DATEADD(month,...如有必要,将自动将其结果的日期部分剪辑到该月的最后一天。因此,如果您总是将月份添加到 31 日的日期,它将产生所需的结果。


(*) 如果不这样做,只需在查询前添加 CTE:

;with Numbers (n) as (
    select 0 union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all
    select 6 union all select 7 union all select 8 union all select 9 union all select 10 union all select 11
)
select DATEADD(month,n,'20120131') from Numbers
