I'm trying to display the parameters within the footer for a reference to the reader of the printed report.
=IIF(Count(Parameters!P_Faculty) >3, "%", "Faculty"&join(Parameters!P_Faculty.Label, ", "))
I wanted to do a count on the number of options of a parameter which are selected so I can limit the display to "%" if there are more than 3 Faculty Parameters selected.
I receive no run-time error instead the text box displays "#ERROR". I'm guessing my error is with the Count(Parameters!P_Faculty)>3
How could I simulate this effect?
Sorry, it turns out I was going about this the wrong way.
I did not know that Parameters have their own Count value:
Parameters!P_UIO_ID.Count
Full solution:
=IIF(Parameters!P_UIO_ID.Count > 3, "%", join(Parameters!P_UIO_ID.Label, ", "))

I'm trying to concatenate a string on the end of a sum, but if the sum is nothing, it breaks. It seems like this is due to SSRS evaluating both conditions of the IIf statement, but I can't figure out how to get around this.
I've got....
=IIf(IsNothing(Sum(Fields!Work.Value)), "", Sum(Fields!Work.Value).ToString + " J")
Which will print out the work summary + " J" if there is one, and #Error if not. What's the SSRS workaround?
Update / Clarification
The report in question is grouping on dates and then summing up Work, so it's not the case that Work is null, per se, but that for this particular date for this particular user, there are no rows in the group.. So, there are no rows to sum up in the error causing instance.
Sample Data Set
Name Date Work
Andy 12/1/15 511.30
Andy 12/1/15 549.70
Drew 12/2/15 484.80
Drew 12/2/15 322.36
Sample Report (current)
Name 12/1/15 12/2/15
Andy 1061 J #Error
Drew #Error 807.16 J
Sample Report (expected)
Name 12/1/15 12/2/15
Andy 1061 J
Drew 807.16 J
Have you considered doing the two parts of your desired output in two different expressions in the same Cell?
I assume for the current structure you have used a matrix, with Rows for the Name, and Columns for the date. You can the set the Data to be Sum of Work, as shown here, and in the red text in the image below.
=Sum(Fields!Work.Value)
You then then right click the cell and select "Create Placeholder" to insert a second expression in the same cell.
Set the value of this expression to be as shown here, and in the blue text below
=iif(Sum(Fields!Work.Value) > 0, " J", "")
Then when the report is run, it will always show the Sum if there is one, and if the value of the Sum is greater than zero, it will also display the J as required.
Hopefully this is the behaviour you require. Please let me know if you require further assistance with this solution
Try this:
=IIF(SUM(IIF(Isnothing(Fields!Total.Value),0,Fields!Total.Value)) = 0,
"",
SUM(IIF(Isnothing(Fields!Total.Value),0,Fields!Total.Value)).ToString + " J"
)
Let me know if this can help you
IIF does not short-circuit so this #Error is from SSRS trying to use the ToString function on NULLs.
The workaround is to add another IsNothing check in the false section before using ToString:
=IIF(IsNothing(Sum(Fields!Work.Value))
, ""
, IIF(IsNothing(Sum(Fields!Work.Value)), "", Sum(Fields!Work.Value)).ToString & " J")
To solve this exact problem, because if there is no Work to display then the report should display nothing, instead of using the IIf statement with concatenation, it is simple and sufficient to set a conditional visibility on the cell.
In the cell, use the expression:
Sum(Fields!Work.Value).ToString + " J"
Then for the same cell, select:
Text Box Properties > Visibility > Show or hide based on an expression
and enter:
=IsNothing(Sum(Fields!Work.Value))
While this solves this specific problem, if the solution requires the empty cell to display anything other than blank, then the original IIf short-circuit issue is still an issue.
How can I limit the number of characters a user can type for a parameter in SSRS?
For example, if the Data Type is set to TEXT, how to limit the user to type only 6 characters after Default value of "CL/" OR limit to total of 9 characters.
Unfortunately you can't perform validation as people write values, you can only handle them when the report is run. You can however use Code behind the report to perform some validation on your Parameters at run-time. Based on the result of this you can then either display the required data to instead return an error message.
To insert some code behind you right click the area around the report, Choose Report Properties, then Code.
Enter something like this into the code panel
Function Validate(param) as Boolean
If len(cstr(param)) <= 9 Then
Return"True"
Else
Return "False"
End if
End Function
You can then refer to the result of this from a text box that displays an error as follows
Right click the text box and set the visibility to be
=iif(Code.Validate(Parameters!myInput.Value) = True, True, False)
Then if you enter a string of 9 or fewer characters you will get an error that you can use to inform the user of the proper format of your desired input string.
Instead of just making text boxes visible/invisible, you could also apply this to rectangles that store your report information. Also, you can use visual basic coding to alter the Code behind to perform more complicated parameter validation to check for you "CLI" string for example.
I hope this helps, let me know if you require further help.

Any help...
Well, there are two ways to do this that I worked out, and neither is particularly elegant so I'd be surprised if someone doesn't have a better solution.
"t.a" in the code below is your table and column.
The SQL way:
SUBSTRING(t.a,1,CHARINDEX(' ',t.a,1))+REPLICATE('_',20)+REVERSE(SUBSTRING(REVERSE(t.a),1,CHARINDEX(' ',REVERSE(t.a),1)))
Change the value being replicated above from '' to ' ' and you are in business. I left it as '' to illustrate what it's doing.
The SSRS way, which is better from a DB standpoint:
=Mid(Fields!a.Value,1,InStr(Fields!a.Value," "))+StrDup(20,"_")+StrReverse(Mid(StrReverse(Fields!a.Value),1,InStr(StrReverse(Fields!a.Value)," ")))
This is precisely the same formula, executed by SSRS instead of by SQL Server.
I once used Switch to append spaces to a column field, like in the following example:
=Switch(LEN(Fields!FamilyMemberName.Value) = 1, " ",
LEN(Fields!FamilyMemberName.Value) = 2, " ",
LEN(Fields!FamilyMemberName.Value) = 3, " ")
But I didn't have to bother about the expression getting longer, since I know exactly how many spaces I should append and it wasn't more than 15.
You could use Switch in your case too or you could write a VB function in the Code tab of Report Properties window and pass the values, use some loops to generate the spaces you require.
Or it's much easier in MS SQL, all you got to do is append SPACE(NoOfSpacesInInteger) to the field.
I have a multi-valued parameter called Faculty on a report. I want to display the selection in a textbox at the top of the report. The obvious solution would be:
JOIN(Parameters!Faculty.Label,", ")
The problem that I am having is that the first option in the list (the default) is "All Faculty". This is distinct from the "Select All" checkbox that SSRS provides. We have created this hardcoded "All" option because it looks cleaner on the parameters screen (the user sees "All Faculty" instead of "Adam, Arbor, Altman..." etc.). If the user leaves this checked and makes any other selections, we assume that they meant to only select the other items and the stored procedure ignores the "All" selection.
So I would like to display something like this:
IIF(Parameters!Faculty.Value(0) = "0000000", [*display all selections except value 0*], (JOIN(Parameters!Faculty.Label,", "))
The section in square brackets is what I am having trouble with. The 0000000 value represents "All Faculty".
Answered by OP in comments to original question:
I ended up using substring. In case anyone else reading this needs the
final code, here it is:
IIF(Parameters!Faculty.Count < 6,
IIF(Parameters!Faculty.Value(0) = "0000000",
IIF(Parameters!Faculty.Count = 1, (JOIN(Parameters!Faculty.Label,";
")), (JOIN(Parameters!Faculty.Label,"; ").Substring(13))),
(JOIN(Parameters!Faculty.Label,"; "))), "Multiple")
I added a check so
that it will only display up to 5 at a time, otherwise it says
"Multiple". I did Substring(13) because "All Faculty; " is 13
characters including spaces.
The solution above worked initially, but failed when the string was
less than 14 characters (due to the IIF). You set me on the right
track and I came up with a fairly elegant solution:
Switch(Parameters!Faculty.Count > 5, "Multiple Selected",
Parameters!Faculty.Count <= 5,
Replace((JOIN(Parameters!Faculty.Label,"; ")),"All Faculty; ",
""))'code'
Customer wants me to repeat the parameter values in the page header of the report. But if they just choose "Select All" on a multi-valued parameter, they want the text "Any" listed.
For example, one parameter has a fixed set of 9 values. I hard-coded the expression for a text box to:
="Room Size: " &
iif(Parameters!pRoomCap.Count=9,
"Any",
Join(Parameters!pRoomCap.Value, ", "))
How can I do this if the parameter source is a query of unknown size?
Try this out. You need to compare the total number of parameters in the dataset to the count of selected parameters. The following assumes that your multivalue parameter is using a dataset called "dsRoomSizes"
="Room Size: "
& iif(Parameters!pRoomCap.Count = count(Fields!pRoomCap.Value,"dsRoomSizes"),
"Any",
Join(Parameters!pRoomCap.Value, ", "))
This expression will work in the page header/footer.
UPDATE
In the interests of finding a solution to your problem, the following should work for you. It feels hackish and I encourage you to keep research alternative methods but this will work:
Create a second multivalue parameter and name it something like "pRoomCap_hidden".
The source of the parameter is the exact same query
In the parameter properties, setting the default values to the same query
Important: Set the parameter visibility to hidden
This will create a second multivalue parameter in your report that is exactly the same as your initial multivalue parameter only this parameter list will have all values selected by default.
Enter the following expression in a textbox in your header:
=IIF(Parameters!pRoomCap.Count = Parameters!pRoomCap_hidden.Count,"All",Join(Parameters!ReportParameter1.Value,", "))
The above will compare the selected values in each parameter list. If the lists contain the same selected values then that indicates that "All" have been selected in the first list.
Like I said, it is hackish but it definitely works. Until you are upgraded to 2008, this might not be a bad workaround for you.
Can you compare the count of the parameter to the count of the dataset you pull the parameter values from?
I unioned my dataset for the parameters with one which I created manually with a "select" statement - I was then able to force the value to be something like -1 or null.
Then simply check if the parameter contains -1 or null and replace the value in the header with the replacement text.
BTW- I am now using SSRS 2008 R2 and this solution worked for me. My report uses three datasets; but only one in the tabilx that I needed to hide a row in. After long hours of searching and many, many, many unhelpful for wrong answers; the solution of creating a identical parameter only hidden (I marked it as internal) and then comparing to the exposed one is brilliant and easy.
Thank you very much!
