datetime - 根据开始日期和日期查询设置我的“结束”/“开始”日期

Question

首先感谢大家昨天的帮助。

我已经成功地让我的报告正常工作(到目前为止)，所以现在我需要在标题中显示日期段(从:到:)。这是查询:

Declare @startdate  datetime
Declare @enddate  datetime
Declare @BeginningDate datetime

set @BeginningDate = '12-01-2011'

IF Month(@BeginningDate) < (Month(GETDATE())-1)--(YTD)
BEGIN
set @startdate = DATEADD(yy, DATEDIFF(yy,0,getdate()), 0)
set @enddate = dateadd(day, datediff(day, 0, getdate()), 0)
END

IF Month(@BeginningDate) = (Month(GETDATE())-1)--(MTD)
BEGIN
set @startdate = dateadd  (mm,-1,
  DATEADD(dd,-(DAY(DATEADD(mm,1,convert(varchar(10),getdate(),111)))-1),
  DATEADD(mm,0,convert(varchar(10),getdate(),111))))--BEGINNING OF PRIOR MONTH
set @enddate =DATEADD(dd,-1,
  DATEADD(mm, 
  DATEDIFF(m,0,convert(varchar(10),getdate(),111)),0))--END OF PRIOR MONTH
END


IF Month(@BeginningDate) = (Month(GETDATE()))--(Current Period)
BEGIN
set @startdate = dateadd(month, datediff(month, 0, 
  dateadd(day, datediff(day, 1, getdate()), 0)), 0)--BEGINNING OF CURRENT MONTH
set @enddate = dateadd(day, 
  datediff(day, 0, getdate()), 0)--THROUGH CURRENT MONTH (TODAY)
END

如果用户输入日期11/27/2011至12-03-2011作为搜索参数，那么我的标题应该显示 FROM: 11/01/2011 TO:11/30/2011 (MTD) 。例如，如果他们选择 12/01/2011至12/08/2011那么我只需要那些日期(当前期间)。如果用户输入10/01/2011-12/8/2011那么该期间将是从 01/01/2011 to 12/8/2011 (YTD) 。

我如何在 SSRS 中将其设置为表达式？我是否需要根据这些输入创建数据集，然后调用参数？我已经使用一个日期时间范围完成了此操作，但从未使用过类似的存在多个时间范围问题的方法。

提前致谢!

更新:这就是我试图在 SSRS 表达式中实现的目标:

="FROM:"&iif(Month(Parameters!BeginningDate.Value < (Month(today()-1)) THEN (DateAdd("d",-DatePart(DateInterval.DayOfYear,Today(),0,0)+1,Today())).tostring("dd/MM/yyyy")+"       "+"TO:today()"

如果用户选择的开始日期大于上个月(例如 10 月 1 日)，则返回的日期应为 1/1/2011至12/16/2011

我希望这能澄清事情。

谢谢!

我之前发布过这个，您需要使用可以调用日期函数的数据集。看看你是否可以按照这个:SQL Server: calculating date ranges它有奇效。具体请查看For Reporting Services Folks 部分。

对你来说，这将非常简单，如果他们选择 11/27/2011 并且你想返回 11/1/2011，你只需调用数据集，该数据集又调用函数month_start。该线程中对此都有详细记录并广泛使用。

要点是你需要RS中的这个功能:

CREATE FUNCTION [dbo].[udfCommonDates] (@date datetime)
RETURNS @t table (week_start datetime,
                  week_end datetime,
                  lastweek_start datetime,
                  lastweek_end datetime,
                  month_start datetime,
                  month_end datetime,
                  lastmonth_start datetime,
                  lastmonth_end datetime,
                  yesterday_start datetime,
                  yesterday_end datetime,
                  today_start datetime,
                  today_end datetime,
                  thisweek_monday_start datetime,
                  thisweek_monday_end datetime,
                  year_start datetime,
                  year_end datetime,
                  tomorrow_noon datetime,
                  today_noon datetime,
                  date_only datetime)
BEGIN
   INSERT @t
   SELECT
   dbo.get_week_start ( @date ) AS week_start,
   dbo.get_week_end   ( @date ) AS week_end,
   dbo.get_week_start ( DATEADD(d, -7, @date ) ) AS lastweek_start,
   dbo.get_week_end   ( DATEADD(d, -7, @date ) ) AS lastweek_end,
   dbo.get_month_start( @date ) AS month_start,
   dbo.get_month_end  ( @date ) AS month_end,
   dbo.get_month_start ( DATEADD(m,-1, @date) ) AS lastmonth_start,
   dbo.get_month_end  ( DATEADD(m,-1,@date) ) AS lastmonth_end,
   dbo.get_yesterday_start ( @date ) AS yesterday_start,
   dbo.get_yesterday_end ( @date ) AS yesterday_end,
   dbo.get_today_start (@date) AS today_start,
   dbo.get_today_end ( @date ) AS today_end,
   dbo.get_weekday_start(1,@date) AS thisweek_monday_start,
   dbo.get_weekday_end(1,@date) AS thisweek_monday_end,
   dbo.get_year_start(@date) AS year_start,
   dbo.get_year_end(@date) AS year_end,  
   dbo.get_tomorrow_noon(@date) AS TomorrowNoon,
   dbo.get_today_noon(@date) AS TodayNoon,
   dbo.get_date_only(@date) AS DateOnly
RETURN
END

然后您需要每个标量值函数:

   CREATE FUNCTION [dbo].[get_date_only] (@date datetime)
    RETURNS datetime
    WITH SCHEMABINDING, RETURNS NULL ON NULL INPUT
    AS

      dateadd(weekday,1-datepart(weekday, @date),@date))-1,0)
END
GO

CREATE FUNCTION [dbo].[get_weekday_end] (@weekday tinyint,
                                 @date datetime)

AS    BEGIN
   return dateadd(yyyy, datepart(yyyy,
      dateadd(weekday,@weekday-
      datepart(weekday, @date),@date))-1900, 0)
    + dateadd(ms, -3,
      dateadd(dy, datepart(dy,
      dateadd(weekday,@weekday-datepart(weekday, @date),
                                        @date)),0) )
END
GO

CREATE FUNCTION [dbo].[get_weekday_start] (@weekday tinyint,
                                   @date datetime)

AS    BEGIN
   return dateadd(yyyy, datepart(yyyy,
      dateadd(weekday,@weekday-
      datepart(weekday, @date),@date))-1900, 0)
    + dateadd(dy, datepart(dy,
      dateadd(weekday,@weekday-datepart(weekday, @date),
                                        @date))-1,0)
END
GO

CREATE FUNCTION [dbo].[get_year_end] (@date datetime)
RETURNS datetime
WITH SCHEMABINDING, RETURNS NULL ON NULL INPUT
AS    BEGIN
RETURN DATEADD(year, DATEDIFF(year, 0, GetDate())+1, 0)-1
END
GO

CREATE FUNCTION [dbo].[get_year_start] (@date datetime)

AS    BEGIN
   RETURN dateadd(day, -1, datediff(d,0,@today))
END
GO

现在报告服务的艰苦工作已经完成，请记住数据集可以是存储过程或直接表。因此，您只需创建一个存储过程:

CREATE PROCEDURE [dbo].[uspCommonDates] AS
begin
   set datefirst 1
   declare @date datetime
   set @date = getdate()
   select * from dbo.udfCommonDates(@date)
end

并使用此存储过程作为数据集。现在您可以使用所有这些不错的日期函数了。因此，您现在可以转到参数部分并像这样调用这些函数:
