Question

我正在使用SQLServer 2008开发一个财务应用程序作为数据库，我希望生成任何一年的财政期间，例如

输入：2010年6月

结果需要从2010年6月 - 2011年5月开始的12个时期

周期...............。开始.............................. .... ......... ..End 1 ... ... .................. 2010年1月6日................................. 30-06-2010 2 .......... 2010年1月7日........... 31-07-2010

依此类推，直到2010年5月......实际上需要从任何月份开始获得12行（12个月），输出将是该月的开始日期，结束将是该月的最后一天，例如在我的场景中2010年6月 - 2011年5月..这将是什么问题。

先谢谢

请参阅DATEADD()

select convert(datetime,'6/1/2010')

select DATEADD(day,-1,DATEADD(month,1,convert(datetime,'6/1/2010')))   --6/30/2010

select DATEADD(month,1,convert(datetime,'6/1/2010'))   --7/1/2010

你可能会在一个存储过程中运行它，这会生成一个临时表，或者只是一个大查询快速而且非常脏......

我毫不犹豫地为你做了整件事，但干草是什么......

create procedure getFiscalYear
  @startDate nvarchar(10)
as begin

declare @myDate datetime
set @myDate = convert(datetime,@startDate)

select 1 as Period, @myDate as startDate, DATEADD(day,-1,DATEADD(month,1,@myDate)) as endDate
union
select 2 as Period, DATEADD(month,1,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,2,@myDate)) as endDate
union
select 3 as Period, DATEADD(month,2,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,3,@myDate)) as endDate
union
select 4 as Period, DATEADD(month,3,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,4,@myDate)) as endDate
union
select 5 as Period, DATEADD(month,4,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,5,@myDate)) as endDate
union
select 6 as Period, DATEADD(month,5,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,6,@myDate)) as endDate
union
select 7 as Period, DATEADD(month,6,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,7,@myDate)) as endDate
union
select 8 as Period, DATEADD(month,7,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,8,@myDate)) as endDate
union
select 9 as Period, DATEADD(month,8,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,9,@myDate)) as endDate
union
select 10 as Period, DATEADD(month,9,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,10,@myDate)) as endDate
union
select 11 as Period, DATEADD(month,10,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,11,@myDate)) as endDate
union
select 12 as Period, DATEADD(month,11,@myDate) as startDate, DATEADD(day,-1,DATEADD(month,12,@myDate)) as endDate

end

这是丑陋的方式......

这是使用公用表表达式创建句点列表的方法。我借用@Fosco的DATEADD方法（thx @Fosco）。

DECLARE @StartDate DATETIME = '06/1/2010';

WITH periods AS
    (SELECT 1 AS period
    UNION SELECT 2
    UNION SELECT 3
    UNION SELECT 4
    UNION SELECT 5
    UNION SELECT 6
    UNION SELECT 7
    UNION SELECT 8
    UNION SELECT 9
    UNION SELECT 10
    UNION SELECT 11
    UNION SELECT 12
    )

SELECT period,
    DATEADD(month,period-1,@StartDate) as startDate,
    DATEADD(day,-1,DATEADD(month,period,@StartDate)) as endDate
FROM periods

有多种方法可以创建您的期间列表。有关示例，请参阅this。
