Question

我正在使用SQL Server 2008.我想获得一年中所有季度的开始日期和结束日期。例如，如果我在查询中传递2013，那么输出应该是

StartDate                 EndDate                   QuarterNo
-------------------------------------------------------------
2013-04-01 00:00:00.000   2013-06-30 00:00:00.000      1
2013-07-01 00:00:00.000   2013-09-30 00:00:00.000      2
2013-10-01 00:00:00.000   2013-12-31 00:00:00.000      3
2014-01-01 00:00:00.000   2014-03-31 00:00:00.000      4

由于从4月1日开始的财政年度，我希望从4月1日开始第一季度开始。我怎样才能得到这个输出？谢谢你的帮助...

Answer 1

select 
    dateadd(M, 3*number, CONVERT(date, CONVERT(varchar(5),@year)+'-1-1')),
    dateadd(D,-1,dateadd(M, 3*number+3, CONVERT(date, CONVERT(varchar(5),@year)+'-1-1'))),
    Number QuarterNo
from master..spt_values 
where type='p' 
and number between 1 and 4

您可能希望使用日期，而不是日期时间，否则您季度中包含季度最后一天的任何内容（例如：2013-06-30 14:15）

另一方面，请使用datepart

select ((DATEPART(q,@date)+2) % 4)+1

Answer 2

另一种方法

SELECT DATEADD(mm, (quarter - 1) * 3, year_date) StartDate,
       DATEADD(dd, -1, DATEADD(mm, quarter * 3, year_date)) EndDate,
       quarter QuarterNo
  FROM
(
  SELECT '2013-04-01' year_date
) s CROSS JOIN 
(
  SELECT 1 quarter UNION ALL
  SELECT 2 UNION ALL
  SELECT 3 UNION ALL
  SELECT 4
) q

输出：

| StartDate  |    EndDate | QuarterNo |
|------------|------------|-----------|
| 2013-04-01 | 2013-06-30 |         1 |
| 2013-07-01 | 2013-09-30 |         2 |
| 2013-10-01 | 2013-12-31 |         3 |
| 2014-01-01 | 2014-03-31 |         4 |

Answer 3

我最喜欢的方式，但SQLServer 2012之前不存在EOMONTH和DATEFROMPARTS：

DECLARE
    @FISCAL_YEAR INT = 2013,
    @QUATER INT = 2
SELECT 
    DATEFROMPARTS(@fiscal_year,(@Quater * 3)-2,1) AS QuaterStart,
    EOMONTH(DATEFROMPARTS(@fiscal_year,@Quater * 3,1)) AS QuaterEnd

Answer 4

在寻找截断日期时偶然发现了这两个帖子。

-- DATE TRUNCATE FORMAT
CAST(DATEADD(datepart, DATEDIFF(datepart, 0, date), 0) AS DATE)

这是我写的一个可能有帮助的示例查询：

DECLARE @datetime DATETIME = GETDATE() -- '2021-08-21 16:48:09.018'

SELECT
  @datetime                                                                                       AS [Date Time]
, CAST(@datetime AS DATE)                                                                         AS [Date]
, DATEPART(QUARTER, @datetime)                                                                    AS [Quarter of Year]
, DATEDIFF(QUARTER, 0, @datetime)                                                                 AS [Quarter Integer]
, DATEDIFF(QUARTER, 0, @datetime) - 1                                                             AS [Previous Quarter Integer]
, DATEDIFF(QUARTER, 0, @datetime) + 1                                                             AS [Next Quarter Integer]
, CAST(DATEADD(QUARTER, DATEDIFF(QUARTER, 0, @datetime), 0) AS DATE)                              AS [Quarter Date 1]
, DATEFROMPARTS(YEAR(@datetime), (DATEPART(QUARTER, @datetime) * 3) - 2, 1)                       AS [Quarter Date 2]
, CAST(DATEADD(QUARTER, DATEDIFF(QUARTER, 0, @datetime) - 1, 0) AS DATE)                          AS [Previous Quarter Start Date 1]
, DATEADD(QUARTER, -1, DATEFROMPARTS(YEAR(@datetime), (DATEPART(QUARTER, @datetime) * 3) - 2, 1)) AS [Previous Quarter Start Date 2]
, CAST(DATEADD(QUARTER, DATEDIFF(QUARTER, 0, @datetime) + 1, 0) AS DATE)                          AS [Next Quarter Start Date 1]
, DATEADD(QUARTER, +1, DATEFROMPARTS(YEAR(@datetime), (DATEPART(QUARTER, @datetime) * 3) - 2, 1)) AS [Next Quarter Start Date 2]
, EOMONTH(DATEFROMPARTS(YEAR(@datetime), DATEPART(QUARTER, @datetime) * 3, 1))                    AS [Quarter End Date 1]
, CAST(DATEADD(DAY, -1, DATEADD(QUARTER, DATEDIFF(QUARTER, 0, @datetime) + 1, 0)) AS DATE)        AS [Quarter End Date 2]
, CAST(DATEADD(DAY, -1, DATEADD(QUARTER, DATEDIFF(QUARTER, 0, @datetime), 0)) AS DATE)            AS [Previous Quarter End Date]
, CAST(DATEADD(DAY, -1, DATEADD(QUARTER, DATEDIFF(QUARTER, 0, @datetime) + 2, 0)) AS DATE)        AS [Next Quarter End Date]

Answer 5

 CREATE FUNCTION cal_quarter (@DATE SMALLDATETIME)

    RETURNS INT
    AS
BEGIN
declare @CalendarQuarter int
        IF month(@DATE) in(4,5,6)
            BEGIN
                set @CalendarQuarter =1
            END
        if month(@DATE) in(7,8,9)
            BEGIN
                set @CalendarQuarter =2
            END
        if month(@DATE) in(10,11,12)
            BEGIN
                set @CalendarQuarter =3
            END
        if month(@DATE) in(1,2,3)
            BEGIN
                set @CalendarQuarter =4
            END
return @CalendarQuarter
END

这是一个返回日历季度的函数。

你应该发送DATE作为参数。希望这有帮助！

Answer 6

上一季度的最后日期。此代码可以在SQL Server 2012及更高版本上运行

select EOMONTH(DATEFROMPARTS(year(DATEADD(month, -1, GETDATE())),DATENAME(qq,DATEADD(month, -1, GETDATE())) * 3,1)) AS QuarterEnd

Answer 7

SELECT 
    CAST(DATEADD(M,3*(NUMBER-1),DATEADD(YYYY,DATEDIFF(YYYY,0,GETDATE()),0)) AS DATE) [QT START DATE]
    , CAST(DATEADD(D,-1,DATEADD(M,3*(NUMBER),DATEADD(YYYY,DATEDIFF(YYYY,0,GETDATE()),0))) AS DATE) [QT END DATE]
    , NUMBER AS [QUARTER NAME]
FROM MASTER..SPT_VALUES 
WHERE TYPE='P' 
    AND NUMBER BETWEEN 1 AND 4

从年份获取Quarters StartDate和EndDate
