Question

我需要检索3个月的数据，例如

我在datetime列中有数据。

Date_Column
11/22/2012
12/22/2012
01/22/2013

当我通过日期12/22/2012时，我需要上面的输出。

我正在使用此但未获得结果。

where
MONTH(Date_Column) BETWEEN MONTH(DATEADD(M,DATEDIFF(M,0,'12/22/2012')-1,0))
                AND MONTH(DATEADD(M,DATEDIFF(M,0,'12/22/2012')+1,0))
                AND YEAR(Date_Column)=YEAR('12/22/2012') 

Group By Month(Date_Column), YEAR(Date_Column)..

提前致谢

Answer 1

如果您想要前一个月，当月和下个月的所有数据

DECLARE @date datetime = '2012-12-22'

SELECT
  * 
FROM
  yourtable
WHERE 
  Date_Column >= DATEADD(M,DATEDIFF(M,0,@date)-1,0) AND
  Date_Column < DATEADD(M,DATEDIFF(M,0,@date)+2,0)

作为文档

DECLARE @date datetime = '2012-12-22'

SELECT 
  DATEADD(M,DATEDIFF(M,0,@date)-1,0) [From],
  DATEADD(M,DATEDIFF(M,0,@date)+2,0) [To]

返回：

From        To
2012-11-01  2013-02-01

Answer 2

我认为你需要写如下：

where
MONTH(Date_Column) BETWEEN MONTH(DATEADD(M,-1,'12/22/2012'))
                AND MONTH(DATEADD(M,+1,'12/22/2012'))

或

where
    Date_Column BETWEEN DATEADD(M,-1,'12/22/2012')
                    AND DATEADD(M,+1,'12/22/2012')

Answer 3

试试这个，

Declare @CurDate datetime
Declare @StartDate datetime
Declare @EndDate datetime
Select @CurDate = GETDATE() --Pass Your Date As parameter
Select  @EndDate=DateAdd(M,+1,@CurDate)
Select  @StartDate= DateAdd(M,-1,@CurDate)
Select @CurDate
Select @EndDate
Select @StartDate
WHERE (MONTH(@StartDate) BETWEEN MONTH(@EndDate) AND MONTH(@StartDate))
AND (YEAR(@StartDate) BETWEEN YEAR(@EndDate) AND YEAR(@StartDate))

Answer 4

试试这个：

这实际上是基于ACCESS，但是如果你能够在sql中转换它，我相信这会起作用

WHERE (((DateDiff("m",Date_Column,'12/22/2012'))=1)) or
 (((DateDiff("m",Date_Column,'12/22/2012'))=0)) or (((DateDiff("m",Date_Column,'12/22/2012'))=-1))

我认为这是必须用SQL编写的：

WHERE Date_Column = DATEDIFF(M, 1 , '12/22/2012') OR
      Date_Column = DATEDIFF(M, 0 , '12/22/2012') OR
      Date_Column = DATEDIFF(M, -1 , '12/22/2012')
