how to make report parameter value change dynamic when run time?

Dear all,

i have 2 parameter [startDate] [endDate].
startDate will basic on the day run report to get the start date from system(follow the store procedure) as below.

CREATE PROCEDURE [dbo].[CFSRep_spGetLastWeekMonDate]
AS
BEGIN
DECLARE @.dtStart DATETIME
-- SET @.dtStart = GetDate() --Set Date to Todays Date
--Set Start Date to 6 days before. If its a Sunday it will get this weeks Monday Date, else any day before will get the past weeks Monday Date
SELECT @.dtStart = dateadd(dd, -6, Getdate())
WHILE (datepart(dw, @.dtStart) != 2) --While its not Day 2 (Monday)
BEGIN
SELECT @.dtStart = dateadd(dd, -1, @.dtStart) --Set the Start Date to a day before
END

SET @.dtStart = CONVERT(DATETIME, FLOOR(CONVERT(FLOAT, @.dtStart))) --Set the time to 00:00:00 AM

SELECT @.dtStart as LastWeekFirstDay
--

END
GO


endDate will get the date after the startDate is process. let say the answer as below.
SELECT DATEADD(dd, 4, @.startDate) as endDate

when i get the startDate = 30th Jan 2006, then the endDate = 3rd Feb 2006

then when i preview report, and i change the parameter of the date on start date to 23rd Jan 2006 but the endDate still the same 3rd Feb 2006.

anyway for me to refesh the endDate to 27th Jan 2006?

Hi Terence,

first of all you can use visual basic functions like Today etc. to get the startdate. In case of that you must not go to the database.

then you can try the following steps:

1. define 2 parameters (startdate + enddate)

2. in the enddate-dataset define a parameter @.startDate and set it to =Parameters!StartDate.Value.

3. make your 'SELECT DATEADD(dd, 4, @.startDate) as endDate' statement.

Now the reportservice should set in the endate-parameter the startdate-param +4 days.

hope this will work for you
