Setting Default Parameters Via The Reporting Services Viewer
Oct 23, 2007
HI,
I am trying to set the following default parameter : datepart("m",now()). The parameter is an integer
If I do this through visual studio 2005 it works just fine.
However I need to change this for a linked report and when I do the same thing in the viewer (using the "Overide Default" key) I get the following error
"The parameter Month contains a value that is not valid. This parameter takes an integer as a value"
Can anyone suggest a way to get arround this ?

Thought I'd help some folks with rs and dates..
here is some scalar valued functions:
CREATE FUNCTION [dbo].[get_date_only] (@date datetime)
RETURNS datetime AS
BEGIN
RETURN dateadd(day, DateDiff(day, 0, GetDate()), 0)
END
CREATE FUNCTION [dbo].[get_month_end] (@date datetime)
RETURNS datetime AS
BEGIN
RETURN dateadd(ms, -3, dateadd (m,datediff(m,0,
dateadd(m,1,@date)),0))
END
CREATE FUNCTION [dbo].[get_month_start] (@date datetime)
RETURNS datetime AS
BEGIN
RETURN dateadd(m,datediff(m,0, @date),0)
END
CREATE FUNCTION [dbo].[get_today_end] (@today datetime)
RETURNS datetime AS
BEGIN
return dateadd(ms, -3, datediff(d,0,dateadd(d,1,@today)))
END
CREATE FUNCTION [dbo].[get_today_noon](@date datetime)
RETURNS datetime
BEGIN
RETURN DATEADD(hh, 12, DATEADD(d,DATEDIFF(d,0, @date),0))
END
CREATE FUNCTION [dbo].[get_today_start] (@today datetime)
RETURNS datetime AS
BEGIN
return dateadd(day, 0, datediff(d,0,@today))
END
CREATE FUNCTION [dbo].[get_tomorrow_noon](@date datetime)
RETURNS datetime
BEGIN
RETURN DATEADD(hh, 12, DATEADD(d,DATEDIFF(d,-1, @date),0))
END
CREATE FUNCTION [dbo].[get_week_end] (@date datetime)
RETURNS datetime AS
BEGIN
return dateadd(yyyy, datepart(yyyy,
dateadd(weekday,7-datepart(weekday, @date),@date))-1900, 0)
+ dateadd(ms, -3,
dateadd(dy, datepart(dy,
dateadd(weekday,7-datepart(weekday, @date),@date)),0) )
END
CREATE FUNCTION [dbo].[get_week_start] (@date datetime)
RETURNS datetime AS
BEGIN
return dateadd(yyyy, datepart(yyyy,
dateadd(weekday,1-datepart(weekday, @date),@date))-1900, 0)
+ dateadd(dy, datepart(dy,
dateadd(weekday,1-datepart(weekday, @date),@date))-1,0)
END
CREATE FUNCTION [dbo].[get_weekday_end] (@weekday tinyint,
@date datetime)
RETURNS 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
CREATE FUNCTION [dbo].[get_weekday_start] (@weekday tinyint,
@date datetime)
RETURNS 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
CREATE FUNCTION [dbo].[get_year_start] (@date datetime)
RETURNS datetime AS
BEGIN
RETURN DATEADD(year,DATEDIFF(year,0, @date),0)
END
CREATE FUNCTION [dbo].[get_yesterday_end] (@today datetime)
RETURNS datetime AS
BEGIN
return dateadd(ms, -3, datediff(d,0,@today))
END
CREATE FUNCTION [dbo].[get_yesterday_start] (@today datetime)
RETURNS datetime AS
BEGIN
RETURN dateadd(day, -1, datediff(d,0,@today))
END
Then create a Table-Valued Function like so:
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
Now the RS folks might be thinking but how does this help me as I need a dataset and a dataset can only be based on a Stored Procedure or a direct table. No problem create the following stored procedure:
CREATE PROCEDURE [dbo].[uspCommonDates] AS
begin
set datefirst 1
declare @date datetime
set @date = getdate()
select * from dbo.udfCommonDates(@date)
end
Now you've got a stored procedure to use as a dataset...Now in reporting services add a new dataset:
Now go to the report parameters section of the report:
Now pick that dataset dsFunctions (or whatever you called it) and then pick any of the value fields from the scalar functions such as:
Now when you run the report it uses the scalars:
If you have questions feel free to ask :).
Hope this helps someone
