Parameters not being used in report processing

Category: SQL Server Reporting Services
Hits: 23398
Once again I've spent a whole morning going in the wrong direction with a convincing SQL script. This article is just a note on when using Business Intelligence Development Studio (BIDS) or Report Builder 2.0 and when previewing the report, the parameters are not accounted for (ie. the SQL query creating the dataset does not use the parameters in its query).


Problems:
  • Given a date, the date format was reverting to US format as opposed to European
  • Given a Campus as a text value, the SQL query was ignoring this completely
  • Hardcoding the scalar local variables worked

I have two parameters that will be submitted (GivenDate and GivenCampus). Consider the following script:
copyraw 
-- ===============================================================================
-- Description:	Gets the room bookings for a week based on a given date and campus
-- ===============================================================================

DECLARE
	@GivenDate datetime,
	@GivenCampus varchar(100),

	@setId varchar(10),
	@weekNumber int,
	@siteId nvarchar(5),
	@baseDate datetime,
	@specifiedDate datetime,
	@specifiedCampus varchar(25)
	
	SET DATEFORMAT dmy

	--SET @GivenDate = '1/7/2011'
	--SET @GivenCampus = 'Lansdowne Campus'
	
	SET @specifiedDate = (SELECT @GivenDate)
	SET @specifiedCampus = (SELECT @GivenCampus)

	-- Get columns SetId and WeekNumber from the weekstructure table based on the given date
	SET @setId = (SELECT TOP 1 SetId FROM WEEKSTRUCTURE WHERE StartDate BETWEEN DATEADD(day, -6, @specifiedDate) AND DATEADD(day, 6, @specifiedDate))
	SET @weekNumber = (SELECT TOP 1 WeekNumber FROM WEEKSTRUCTURE WHERE StartDate BETWEEN DATEADD(day, -6, @specifiedDate) AND DATEADD(day, 1, @specifiedDate))

	SET @siteId = (SELECT TOP 1 SiteId FROM SITES WHERE SiteName=@specifiedCampus AND SetId=@setId)
		
	-- Get the start date for the week in question
	SET @baseDate = (SELECT TOP 1 StartDate FROM WEEKSTRUCTURE WHERE StartDate BETWEEN DATEADD(day, -6, @specifiedDate) AND DATEADD(day, 1, @specifiedDate))

I even separated off the @GivenDate and @GivenCampus and re-assigned them mid-script which made no difference whatsoever.

In case you've been stuck for ages (as I have), I found out you cannot declare the parameters used by the software within the SQL script... So the above should look more like this:

Importantly, note the following:
  1. SET DATEFORMAT dmy returns the date in European format irrespective of the regional settings of either the client or the reporting server.
  2. Removed @GivenDate datetime, from the SQL script
  3. Removed @GivenCampus varchar(100) from the SQL script
