I'm not seeing another thread that quite encompasses my scenario: the report I'm modifying has a parameter that I want to make optional, but it is comprised of 3 fields. There is a first name and last name field in which you can start typing, and with the use of a LIKE operator, the actual parameter (Authority) used in the main data pull populates with options that match:
So I've attempted ensuring that the parameters (all 3) have the 'allow blank' and 'allow NULL' checkboxes marked. I've also modified that parameter within the dataset properties to account for NULL:
Lastly, my main query's WHERE clause has the following line: and (data.AuthorityName = #Authority or #Authority is null)
When I declare this variable and set it to NULL, the query does exactly what I want it to, it pulls the data irrespective of what's in this column. But for some reason, I cannot get the report to pull anything. I click View Report and nothing happens. Any ideas?

I had similar question for sub report and was answered:
SSRS passing multiple string parameter to another report
However this time I would like to pass my parameters to a different report instead of a sub report.
For the first report, my ponum parameter consist of string like 'a-01', 'b-02', 'c-44'...
and then perform a query that like
select column_X from table_1 where ponum in (#ponum)
and then user click on a expression link which send the rows to another report to perform another action via a query. such as
update table_1 set column_A = '123' where ponum in (#ponum)
My problem is I can't send the parameter as a multiple values parameter. I added an expression for user to click and added the parameter in this window
I also tried
=join(Parameters!ponum.Value,", ")
="'"+join(Parameters!ponum.Value,"', '")+"'"
In Report_2, I set up the parameter as this
Unfortunately, the report it goes to only receive the first value or the query doesn't work and parameter being the problem.
Would like to hear any idea that might work.
Thanks in advance.
I'm working in report builder, calling a stored procedure that has a parameter that, when null, sets itself to a certain value. I want to display what this parameter is set to on the report. From experimenting, Report Builder's parameter collection only shows the parameter as it is sent from the report.
Alternatives that I've considered but can't get to work or are sub-optimal:
Adding the parameter to the select statement. The main drawback is this won't display a value if there are no results.
Using a return value or output parameter. There doesn't seem to be a way to do this.
Re-creating the "null" logic in the stored procedure. The correct output is displayed but this is a code fork.
How can I display this value? Is there a way to show a return value or output value?
You could change the procedure to return the parameter value in a UNION ALL select so that a row with the parameter value will always be returned. That row could have NULL for all the other columns so that you can filter it out in the rest of the report.
Another possibility is to add a second dataset to the report that does nothing but get the value of the parameter based on what you pass. That, however, is also a sort of code fork. The fork could be mitigated, however, by putting it in a UDF, and resourcing the same UDF in both datasets.
Yet another possibility is to replicate the logic of populating the parameter in a Custom Code block in the report. However, that is also a code fork.
I've never worked in Report Builder interface but I do have quite a bit of experience building reports in BIDS/VS... There it's a simple matter of setting the parameter default, in the rdl, to match the default in the stored procedure.
The issue:
I'm working on a SSRS report, but have encountered some quite strange behavior when I populate a DropDown (another paramter, named "Group") using a DataSet that uses another parameter that is passed in through the URL.
The problem is that I want the Group-parameter to be updated from the URL parameter TrackerTypeID, which works absolutely fine in other cases. Though this is the first time I have a parameter depending on another parameter in its DataSet.
However if I have TrackerTypeID as a visible parameter and manually change the integer value of the parameter the DropDown parameter (Group) is updated accordingly.
What I've done:
So I have a hidden parameter that is passed in through the URL called TrackerTypeID. This parameter is then used in the where-clause of the DataSet that populates another parameter:
SELECT
ID,
TrackerGroupDescription
FROM
vw_TRK_TrackerGroup_LK
WHERE
TrackerTypeID = #TrackerTypeID
Union SELECT Null, '-- Select All --'
As you may suspect it uses the Available Values in Parameter properties to set the available values from a query.
What I expect to happen:
As you might have already suspected I wish for the DropDown parameter to be
I got the Tumbleweed badge for this question.... :)
I've moved on a little from the original question but still looking at using internal/hidden parameters, this time passing to another report which runs a stored procedure (which sends an email).
The main report (report A) has a parameter called StudentCourses (originally called ReportParameter1) which I have tried both as Hidden or Internal, and currently has ticked Allow blank value and Allow multiple values.
(Its default value is a field from the result of a query, which shows the courses a student is enrolled on).
Action for my textbox no longer goes to URL (to open PHP form) but now uses Go to report to call report B. Under action options I've added two parameters; StudNetworkID and StudCourses. The number of courses can vary from 2 to 5.
The new report (report B) has two parameters also called StudNetworkID and StudCourses; both are Hidden and StudCourses has ticked Allow blank value. [All parameters are text, btw].
If Report A StudCourses is set to =Parameters!StudentCourses.Value(0) then the first course is shown on Report B. So far so good.
If Report B StudCourses is set to Allow multiple values, then Report B shows #Error and the Warning description given is "[rsInvalidExpressionDataType] The Value expression used in textrun ‘Textbox3.Paragraphs[0].TextRuns[0]’ returned a data type that is not valid."
If Report B StudCourses is set to NOT Allow multiple values and Report A StudCourses value is set to [#StudentCourses] then Report B shows the text "[#StudentCourses]".
If Report B StudCourses is set to Allow multiple values again, then I get the same invalid data type error as before.
Having turned off Allow multiple values on Report B to avoid the #Error issue...
Setting Report A StudCourses to =Parameters!StudentCourses.Value(0) & Parameters!StudentCourses.Value(1) then Report B shows course 1 and course 2 on one line. OK so far.
However, setting Report A StudCourses to =Parameters!StudentCourses.Value(0) & Parameters!StudentCourses.Value(1) & Parameters!StudentCourses.Value(2) gives me a runtime error that the Index was outside the bounds of the array (because there are currently only two courses). On clicking the textbox, Report B just says "The 'StudCourses' parameter is missing a value".
OK...
I turned off Allow multiple values on Report A StudentCourses parameter (the one holding the result from the query) and for the Go to report parameter StudCourses I added the other values, so eventually had value(0) to value(4), the result was interesting. For each parameter value used it gave me a letter from the first course on Report B. Hence when I included up to value(4) it gave me the first five letters of course one!
Yep, ok, this is because it is no longer reading multiple values and so specifying a number just returns the letter from that position.
SO...
How do I allow for up to 5 courses to be passed over???
What follows below is the original question
I have a small report designed in Visual Studio that displays courses that a student is enrolled on. The number of courses can vary from 2 to 5, depending on the student.
Also on the report is a text box, which when clicked will action a url to open a PHP form.
I have worked out how to pass the user id to this PHP form but, if possible, I would also like to pass the course titles.
If I use internal report parameters* I can add these to the url, like this:
="http://myurl/webform.php?param=" & Mid(User!UserID,InStrRev(User!UserID,"\")+1)
& Parameters!ReportParameter1.Value(0)
& Parameters!ReportParameter1.Value(1)
& Parameters!ReportParameter1.Value(2)
& Parameters!ReportParameter1.Value(3)
& Parameters!ReportParameter1.Value(4)
but unfortunately I get the runtime error "The Hyperlink expression for the text box 'Textbox7' contains an error: Index was outside the bounds of the array."
If I just put the first two report parameters it works fine.
I tried using parameter count, e.g. iif(Parameters!ReportParameter1.Count > 2, Parameters!ReportParameter1.Value(2), " "), but I still get the same error.
Please can someone show me how to get around this runtime error, or suggest another way to do this?
Thanks
PS * Report Parameters set up as Text, Allow blank value, Allow multiple values, Internal, Available Values = None, Default Values = Get values from a query; Value field = course title.
I have a report which requests a parameter value for customerNo. The report should return all values by default.
Once the user provides a single customerNo value, then it should display the specified record only.
I've found solutions for Multiple selection, but couldn't find for single text box entry.
Thanks guys..
Report Design
Change the report parameter to allow NULL:
Modify the WHERE clause of the data set to check NULL parameter value:
Report Execution
When the report is run, users can check NULL for all rows:
Or rows matching a specific value:
