Null Hidden Parameter
Aug 1, 2007
In my report I have a dataset that is returning an ID field among other things. I am setting a hidden parameter = to that ID field. That parameter is then used to return another dataset.
My problem is that the original dataset with the ID field does not always bring back data (this is expected). If data is not brought back, I get an error when I try to execute the report ("The 'X' parameter is missing a value").
I have the parameter set to "Allow Null Values".
This value is not required in the SQL Server stored procedure that returns values for the new dataset.
The parameter is of type Integer. (So I am not able to set the "Allow Blank Value" property)
This is NOT a multi-value parameter.
Does anyone have any suggestions/ideas/workarounds to solve my problem?

I have 2 datasets in my report and I want to pass a field from the 1st dataset as a parameter to the 2nd dataset.
How can I do this?
I tried to set the report parameter from a query using the 1st dataset but the parameter is always equal to the first record in the recordset-it never changes per row.

I have a working set of parameters, when they are all visible. However, when I change the second parameter to hidden it stops working.
First Parameter - Contains static values 'MTD' & Daily
Second Parameter - has available values and a default. Set up to be invalidated when the First parameter changes... like i say it works beautifully when not hidden.
Third Parameter - has an expression takes the value of the 2nd parameter value, removes the first character off and then converts the remainder to a date and uses it as its default value.
It based on this webpage: URL....However, when i set the second parameter to hidden it no longer works.

Given a model in Power Pivot with a number of KPIs that are hidden with the 'hide from client tools' option. After restoring the model in SSAS and connecting to the model from Excel, the KPIs are visible under a separate category/table "KPIs".
Other hidden items in the model like columns and measures remain invisible.
Is this normal behavior and what can I do about this?

We have 1000s of SSRS reports hosted on the SQL 2008 R2. All reports are supposed to have all parameters "hidden". Random reports have been reported to expose the parameter when developers accidently deploy to test servers. Is there a way to identify the reports and the parameter property (Hidden, Visible, Internal) from the Report server Database?
I checked executionlog2 but can not find the parameter property.

There is a multi value parameter called "include" in the report where "Allow Multiple Values" is checked and it has 4 Available values as shown in the attached screen shots and preview of the report is also shown .There is no data set for this parameter and the values will get displayed on the report based on the visibility condition set in the report.Example : If first value is selected then 1 is passed and based on the visibility condition set in the report - the report output is displayed.None is default value and has value 4 and when the report is run with this option i.e. "None" then rest three parameter values are not applicable .
Requirement :
-When the end user selects (Select All) Check box then (None)
-check box must be disabled or must not appear for selection for the end user
-When the end user selects check boxes either of the first three except None then also None check box must be disabled or must not appear for -selection for the end user
-when the end user selects a combination of first three then also None check box must be disabled or must not appear for selection for the end user
-The None is set as default with a value as 4 and is applicable only when the user does not select either of the first three values and the report will run.

In my report i have CNAME parameter , which allows null value. I checked Allow null value check box in report parameter properties.
when i preview the report , it displays checked NULL check box beside CNAME parameter . I want to give some meaningful name(i.e.ALLCustomers) to this checkbox instead of NULL.
Is it possible through SSRS designer?

I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.
The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.
Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.
An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help

Hi,
I am starting to use reporting services and I created a report that takes 4 parameters for a Filter on the dataset.
The idea is the create snapshot nightly and then display the report filtered based on parameters to users.
I'd like that the filter be ignored for a parameter if the parameter is passed as NULL,
Right now I defined it this way :
Left =Fields!RegionCode.Value
Operator =
Right =IIF(IsNothing(Parameters!RegionCode.Value),Fields!RegionCode.Value,Parameters!RegionCode.Value)
I do this for the 4 parameters that are passed, if they are null, make then equals to the field.
I was wondering if there is a way to ignore the whole parameter all together, I would guess it'll be faster to execute.
Thanks

Hello,
I have a group I'll call G4.
The header table row for G4 contains 3 textboxes containing the sums of the contents within G4. The header table row for G4 is visible while it's contents, including the G4 footer table row, is kept invisible until the report user drills down into the group.
When the report user drills down into G4 the footer table row becomes visible and the sums of the contents of the group are displayed for a second time.
At this point I want the sums in the header to be set to invisible when the sums in the footer are made visible by the drilldown.
When I try to reference the hidden property of textbox66 in the G4 footer in order to set the hidden property of header textbox57 in the G4 header I get to this point...
=IIF(reportitems!textbox66.
When it fails to give me an option of choosing the .Hidden property and instead only gives me a .Value.
If I complete the IIF statement manually so that it spells out .....
=IIF(ReportItems!Textbox66.Hidden = False, True, False)
...the report chokes on it.
So my question is, how do I reference the hidden property of one or more textboxes in a group to use as condition checks to set the hidden property of another textbox in that same group?
Thank you for any help you can provide. We are only now beginning to implement reporting services and I have not yet had the chance to research this in greater detail for lack of time.

I have a sql proc. I need to make a parameter optional. I've setup the parameter to use a dataset as its source, and I need NOT to allow the value to be null. I've NOT selected allow nulls check box, But, when the parameter is null (‘’), still data comes back in a table as empty or if it is date will default to 1/1/1900. How do I send a null value to the database through sql proc and raise an error without inserting a null value? I’m hoping to avoid creating a special query just for that purpose.
Thanks.

I Created a Procedure that Generates an ID value based in the current Date (Year/Month) and a value which are stored in a table. This ID value is update in the table, and passed on to an output parameter as folows:
Code Snippet
CREATE PROCEDURE [dbo].[CNSPGetNewGuideID]
@SectionID bigint
,@Year bigint
,@Month bigint
,@ID bigint output
AS
BEGIN
(...)
SELECT @ID = [Year]* 10000000 + [Month] * 100000 + [Number]
FROM [dbo].[CNGuideID]
WHERE [Year] = @Year
AND [Month] = @Month
print 'New ID : '
print @ID
END
This is working and the value printed here is the correct one.
but when I execute the procedure inside another one, the variable i pass on as an output parameter remains NULL...
Code Snippet
CREATE PROCEDURE [dbo].[CNSPInsertNewGuide]
@SectionID int
,@ClientID int
,@UsuaryID bigint
,@UsuarySectionID int
,@ID int OUTPUT
AS
BEGIN
DECLARE @Date as datetime
DECLARE @Year as int
DECLARE @Month as int
SET @Date = GetDate()
SET @Year = YEAR(@Date)
SET @Month = MONTH(@Date)
EXEC CNSPGetNewGuideID @sectionID,@Year,@month,@ID
(...)
I also tried just declaring a variable and executing the procedure but the same thing happens
Code Snippet
declare @ID2 bigint
EXEC CNSPGetNewGuideID 06,2008,03, @ID2
print 'ID : '
print @ID2
this is the result I get:
New ID :
20080300030
ID :
I must be missing something...
Can anyone help?
thanks.

Hi all,
I'm passing a list of values to a stored procedure using an XML parameter - using SQL 2005.
The stored procedure is used to search a table for matching values so this list can contain one or many values, or could be NULL to indicate all values should be returned.
Returning one or more than one value works fine in the code sample given below. How can I phrase my query to cope with the scenario of the parameter being NULL to select all values?
I currently have the following code to cope with one or many values being passed:
Code Snippet
SELECT * FROM dbo.MyTable
WHERE idField IN
(SELECT paramvalues.id.value('.', 'int') FROM @testxml.nodes('/rootnode/idfieldvalue') as paramvalues(id))
where @testxml is the XML parameter passed into the stored procedure.
Thanks as always

In the report I created, there is a drop down used as a parameter, i.e. Sector.
This drop down gets populated with data. It also has <Select a Value> in there.
When no item is selected, i.e. only <Select a Value> is shown in the drop down list, when the view Report button is clicked, the message says:
Please select a value for the parameter 'Sector'
The view Report used a stored procedure which allows null for this Sector parameter.
The SP does work fine in the sql server query analyser because it returns data with and without the sector parameter.
Any thoughts please?
Thanks

We are using forms authentication with SSRS2005 and we are able to access Report Manager (http://servername/reports) and Reportserver (http://servername/reportserver). The problem we are having is every time we add a user to the Content Manager or the Publisher role. The user is able to login and reach the Report Manager but no folder is showing up and also we have the following error message : "Key cannot be null. Parameter name: key".
We removed users from the Content Manager and Publisher Roles and they are able to reach report manager and see the folders. This only happens with report manager. everything works fine with reportserver(http://servername/reportserver).
Any idea why we're getting an error message when trying to assign the Content Manager and publisher Roles to a user.

Hi:I have an application in which I am producing a lists of media outlets based on a number of 6 possible parameters including location, medium, format, scope, language and coverage. I have an interface in which users can select some or all of the possible parameters. Where they don't choose a parameter - e.g. location, I would like the SELECT query to include all locations. I am at the point now of writing 6 X 6 = 36 possible queries to handle the different combinations of possible parameters. This seems a bit excessive and clumsy. I am just learning about stored procedures and was wondering if it is possible to create a procedure that would accept the 6 parameters including ones with null or 0 values and generate a query that would ignore those that were null or zero. Any help in this regard greatly appreciated.Roger Swetnam

Hello,
I have a multi-value parameter field and each item comes from a table in the DB.
This multi-value parameter allows to select all or some of the items.
What if I don't want to select ANY item??
I read in the forum the several tray to do the same but the answers are not so clear..
If I say that at the end is a bug in SSRS... AM I right?
Thank you

Hi,
I have a report with datetime parameter which is required to be optional (there should be an option not to select this parameter which would cause in not narrowing result of this report by this parameter).
I used datetime parameter (to have the calendar control for selecting date) for which I enabled NULL value. The result is that next to this parameter there is a checkbox "NULL" which allows to send NULL as a value of this parameter. Everything is fine except for the prompt: "NULL"... Is there a way to change it? I would see there something like "Empty" or "Not selected", which would be understandable for users of the report.
Or is there any other way to send an empty date as a value of this parameter? (Setting some unusual value like 1/1/1900 for empty date is not sufficient as the empty value shouldn't appear in the parameter control).
Thank you,
Michal

I am having a trouble when I try to retrieve a SQL parameter outside to .Net Clr
I did a clr example like this:

using System.Data.SqlClient;
using System.Data.SqlTypes;
using System.Text;
using Microsoft.SqlServer.Server;
[Code] ...
I now my trouble and it is because the parameter @p_it is null when I try to sed it to pipe in SqlContex but really it is not null. When I test the clr with this code:
CREATE ASSEMBLY
[Test]
FROM
N'Z:SomeRouteTest.dll'
WITH PERMISSION_SET = SAFE
GO
CREATE PROCEDURE [dbo].[Test]

Hi All,
I have a problem while trying to set "NULL" value to my datetime parameters.
I have two datetime parameters (AllowNull=True) on my report. (BeginDate and EndDate)
it works fine in preview mode in reporting design.
The problem occurs, if I try to set an emtpy value to these parameters in my asp.net application.
The code looks like;
Dim repParams(1) As ReportParameter
repParams(0) = New ReportParameter("BeginDate", String.Empty)
repParams(1) = New ReportParameter("EndDate", String.Empty)
-----
ReportParameter method requires String parameters. If user set any datetime value, I am sending "String.Empty" value to my paramaters in order to set them as NULL. But I am getting "rsReportParameterTypeMismatch Error."
How Can I set NULL value to these parameters from asp.net application?
Thans alot in advance.

I have the following database structure:
The table aspnet_users, which we all know
Another table with an uniqueidentifier which references the user iD
I want to set the value of the iD in one of the entries in the second table to null.
I tried this:
string assigned is null, i am passing this as a method parameter
...............
string queryString = "UPDATE [table2] SET AssignedUserId=@assigned WHERE ProblemId = @id";
System.Data.IDbCommand dbCommand = new System.Data.SqlClient.SqlCommand();
...................
System.Data.IDataParameter dbParam_au_pr = new System.Data.SqlClient.SqlParameter();
dbParam_au_pr.ParameterName = "@assigned";
if (assigned == null)
{
dbParam_au_pr.Value = null;
}
else
{
dbParam_au_pr.Value = assigned;
}
dbParam_au_pr.DbType = System.Data.DbType.String ;
dbCommand.Parameters.Add(dbParam_au_pr);
I also tried using "" instead of null, or not using that "if" statement at all.
I get an error that says:
Parameterized Query '(@id nvarchar(1),@assigned
nvarchar(4000))UPDATE [tracker_Probl' expects parameter @assigned,
which was not supplied.
Please help with this as soon as possible.Thanks

I'm trying to write a stored procedure for a search criteria. A user will have few controls on ASP.Net webpage to enter/select the search criteria, based on which , it returns the data.
A Textbox( to enter Username), A Textbox (to enter Employee name),
A DropDownList (To select the profile. Its Id is sent as parameter) &
A DropDownList (To select status). This is where I am stuck.
The last dropdown has 3 list items
1. --All-- value is null/empty
2. Active value is 0
3. Blocked value is 1
Though the Database table will have only 0's and 1's for the status column, the user should be able to see all records when -all-- is selected.I also tried excluding the status parameter and its condition, but no luck either way.

When I run the Query I get...

I also get this when the parameter can be a string.
I have set the parameter properties so that SourceColumnNullMaping to true (it was set as false - so hoped this might fix it!)

I have a parameter in my report, and if it is set to Null or Zero, I want to hide a column. How would I do this? I have already tried using
Code Snippet=IIF(Parameters!Rate.Value >= 0, false, true)
in the Visibility property for the relevant column, but it doesn't make any difference. The column still shows up even if the Rate parameter is set to Null or zero. I only want the column to show if the user enters a value in the Rate parameter which is greater than zero.
