I have a drilldown report whose parameters are: parent report - #valid Nvarchar(20) = '' and in child report - #valid Nvarchar(20) = Null.
Both reports run very well but I have an issue after mapping up this parameters in the Text Box Properties > Action > Go to Report. When the report is run I get the error,
"the value provided for the report parameter is not valid"
The query for this report is from a stored Procedure. In the child report, Parameter Properties, I have ticked the "allow Null values" text box, Set available parameter to come from a query and specify a default value to come from a query. What have I done wrong to allow for the error returned? Your help is appreciated.
Thank you.
If you're second report is expecting a NULL values, (i.e. Nothing in SSRS), you can pass an expression-based parameter to the child report based on the parent parameter, making sure that if it's an empty string at the parent level, you can explicitly set this to Nothing:
=IIf(Parameters!valid.Value = "", Nothing, Parameters!valid.Value)
This way the empty string will never get passed and your child report; only the NULL value it expects.
if you're considering passing a null parameter from URL, let's say some sort of CLI, you must include a parameter:isNull=True in the parameter section of the URL. and allways remenber to check the "allow null value" in report editor, parameter properties.
let's say we have a report, of sports and stadiums, and we have a null sport... it would be something like this>
http://<server/report>&rs:Command=Render&rc:Parameters=false&rc:toolbar=false&sport:isNull=True&stadium=CampNou
Set the Parameter to Allow Blank = Yes and the Default Value = "". In the code make allowances for the blank parameter.

I need to run the report, without selecting anything, with parameter field blank, and be able to view all the data.
the problem is that it necessarily asks me to enter a value (all or multi values).
Who can help me?
If you make sure that you do the following...
Set the parameter to "Allow blank value" and/or "Allow null value" depending on what datatype it is.
Set the default value to Blank (="") if applicable
If you have a list of available values set, make sure the default value is included.
The following example uses sample data from sample database and contains just a list of company names and their ID's.
The main dataset query filters the data based on 2 parameters (one is text the other id numeric to show different scenarios)
This is the dataset query
SELECT CustomerID, CompanyName
FROM [AdventureWorksLT2019].[SalesLT].[Customer2]
WHERE CompanyName LIKE '%' + #pSearch + '%'
and CustomerID > ISNULL(#pID, 0)
ORDER by CompanyName
The report design looks like this with 2 parameters defined
The first parameter is text and has "Allow blanks values" checked, the Default value is set to an expression =""
The second parameter is an integer, This time we have set "Allow null value" on but we have not set a default value.
Note: Neither parameter has any available values set...
When the report is run I get the following results without pressing anything.
Only if I manually set any of the parameters do I need to press View Report, but when the report first runs, there is no need to click anything.
If the above does not help, then show how the parameter(s) are setup up, what types they are, what the available values are and what the default values are.
I have an SSRS report that has a hidden parameter that is based on a dataset. the parameter is multivalued and is set as the default value as well. If the dataset returns no data is there a way to suppress the message during report preview "The parameter name is missing a value" and continue to load report.
I've not tested this but I would do something like...
Allow null values on the parameter.
Then in your report check the number of selected items in your parameter and set the hidden property of a text box (with your info/warning in) to show the textbox if something nothing is selected. Set the Hidden property to something like
=Parameters!myParameter.Count >0
Alternatively check the first value is not empty with something like
=LEN(Parameters!myParameter.Value(0)) > 0
I would like to know if it is possible in report manager to give a specific linked report a "Select all" as default for a parameter.
Here is where i want to set the parameter to select all:
in Report Builder or Visual Studio:
create the parameter query like:
select null as value, '<ALL>' as label
union all
select distinct value, label from xxxxxxxx
this will return the values with specific row on the top.
now in your dataset where clause you can set the following and it will return all or whatever is selected:
XXXXX=CASE WHEN #parameter IS NULL THEN XXXXX ELSE #parameter END
set the XXXXX to the column that provides the parameter info, make sure you set the parameter to accept null values.
Then all you have to do in SSRS is pass null into that parameter
set the default value as 'NULL' in the parameter
There is probably a different, easier way but it works for me.
In order to do something like this, you will have to provide a list of possible values for the parameter. This can be done either by using the Specify values in the Available Values, or the Get values from a query option, in the parameter properties.
This is done in the report designer, or Report Builder. It cannot be done reliably via Report Manager (like in your screen capture).
Once you have that in place, make sure the default values for the parameter are set to all available values.
I have passed one parameter to report server url.
http://<your server>/ReportServer?/<folder>/<reportname>&UserID=Name
How can I read UserID value in report.
Or
How can I print this value in any of the textbox to check what is passed to it?
For example: Above url should show 'Name'.
Based on your comments I think you've figured this out already, but all you should need is the parameter UserId to exist on the report and it will get its value from the query string.
A couple other problems that can crop up when trying to pass a parameter:
Report parameters are case sensitive
Report parameters with visibility set to Internal can't be passed a value through URL
See also: Pass a report parameter within a URL on MSDN
You can try with the Built-In SSRS fields ...
Try using Expression -> Built-In-Fields -> UserId should work in this case, if I understood your question correctly...
OR
Try manipulating the report server URL. Provided below one for example ...
=mid(Globals!ReportServerUrl , InStr(Globals!ReportServerUrl,"&UserID=")+8)
Issue was with my parameter UserId.
I have set it as Internal that's why it was set to default value blank space instead of passed parameter UserId value. (Now I am using hidden)
Note: Report parameters are case sensitive so in my case it must be UserId
In my report, I have an expression which is used to pass a parameter to a child report parameter which is set to allow null values. The expression is :
=IIf(Parameters!Lead.Value = "False",Nothing,Fields!Paid.Value)
The above expression returns values only when Fields!Paid.Value is not blank. Therefore when Fields!Paid.Value is blank I get an error
"the value provided for the report parameter is not valid"
How do I modify my expression to parse these two conflicting issues?
What I want is to be able to return values when the Fields!Paid.Value is blank or when it is not. So at all time when the expression runs corresponding values are returned without the error stated above.
Thanks for helping out.
The first thing you do, wherever you have used the "Paid" parameter, set it to allow null value. Allow null only not blank.
The second thing about the expression, use something like this,
=IIF(Parameters!Lead.Value "FALSE", Nothing, IIF(IsNothing(Fields!Paid.Value),0,Fields!Paid.Value)
