订阅中的SSRS默认参数值

Question

我有一个报告，其中包含两个用户输入的日期参数。我想创建一个在周五运行的订阅，该订阅将在前一周的周日到周六期间进行。因此，例如，对于即将到来的星期五，订阅将在1月29日 - 2月4日进行。我已尝试=Now(), =Today(), @ExecutionTime然后减去天数，但我得到的只是错误。这可能吗？

我确实看到了这个链接，但我想知道是否有更好的方法。 http://www.sqlservercentral.com/articles/Development/datadrivensubscriptions/2432/

Answer 1

是的，我已经这样做了，请看这篇文章https://stackoverflow.com/a/5539615/168703 您可以创建一个获取日期范围的数据集，并在报告中使用它。然后您的订阅可以使用此日期范围并动态更改，而无需每天/每周/每月/每年/等手动更改。

此处也转载，这是您最灵活的解决方案：

我还会分享一组我使用的常用日期函数。只需将其创建为表值函数：

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go

CREATE FUNCTION [dbo].[udfCommonDates] (@date datetime)
RETURNS @t table (week_start datetime,
                  week_end datetime,

这些对我很有帮助，因为我在日期参数的报告服务中使用了它。您可以简单地创建一个引用此表函数的数据集，然后在RS中的任何日期时间的参数中使用这些数据集。

你可以像这样执行整个表值函数：

SELECT * FROM [MyDB]。[dbo]。[udfCommonDates]（GetDate（））

结果是这样的

对于Reporting Services人员

现在我刚才提到我将这些用于报告服务。 现在RS人们可能在想，但这对我有何帮助，因为我需要一个数据集，而数据集只能基于存储过程或直接表。没问题创建以下存储过程：

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

现在您已经有一个存储过程用作数据集......现在在报告服务中添加一个新数据集：

现在转到报告的报告参数部分：

现在选择数据集dsFunctions（或你称之为的任何数据集），然后从标量函数中选择任何值字段，例如：

现在，当您运行报告时，它会使用标量：

现在也在您的＆＃34;订阅＆＃34;你会看到＆＃34;使用默认＆＃34;旁边的复选框 日期的参数。如果选中此复选框，它将自动使用默认值 此自定义函数提供的值。它非常灵活，是报告服务的一个非常好的解决方案。这是一个丝网印刷：

Answer 2

在报表参数配置上（在开发时，而不是在订阅创建时），为参数添加默认值。如果这样做，您将在创建订阅时使用一个名为“使用默认值”的复选框

Answer 3

我最喜欢处理这种情况的技巧是创建一个名为StartWeek的Integer参数。提示“周开始：”可用值如：

Value    Label
 -4      =dateadd("d",0-weekday(today)+2+(-4*7),today).ToString("m")
 -3      =dateadd("d",0-weekday(today)+2+(-3*7),today).ToString("m")
 -2      =dateadd("d",0-weekday(today)+2+(-2*7),today).ToString("m")
 -1      Previous Week
  0      Current Week
  1      Last Month
  2      This Month

默认值-1。

然后在你的查询中：

DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME

DECLARE @CurrentDate DATETIME
SET @CurrentDate = GETDATE()
--SET @CurrentDate = 'October 31, 2011'  -- for debugging

IF ( @StartWeek > 0 ) 
   BEGIN
      SET @StartDate = DATEADD(mm, DATEDIFF(mm, 0, @CurrentDate), 0)
      SET @StartDate = DATEADD(mm, 2 - @StartWeek, @StartDate)
      SET @EndDate = DATEADD(s, -1, DATEADD(mm, 1, @StartDate))
   END
ELSE 
   BEGIN
      SET @StartDate = DATEADD(wk,
                               DATEDIFF(wk, 0, DATEADD(d, -1, @CurrentDate))
                               + @StartWeek, 0)
      SET @EndDate = DATEADD(s, -1, DATEADD(day, 7, @StartDate))
   END

Select
   *
FROM
   MyTable
WHERE
   BeginDate <= @EndDate
   AND FinishDate >= @StartDate

Answer 4

BEGINDATE

=DateAdd("d", -12, Today())

结束日期

=DateAdd("d", -6, Today())

所以即将于2月10日星期五举行。这会给你一个1/29 - 2/4的日期范围。
