This SO link, WHERE Caluse in SSRS expression, verifies that my syntax is correct yet I get this error:
"An error occurred during local report processing.
The definition of the report is invalid.
The Value expression for the text box 'txt1A_EMA' uses an aggregate expression without a scope. A scope is required for all aggregates used outside of a data region unless the report contains exactly one dataset."
My expression:
=Sum(IIF((Fields!COU_EMA.Value, "CA_Summary") = 1, (Fields!Amount.Value, "CA_Summary"), 0))
There are 3 Datasets in my report. The one I want is "CA_Summary" and the expression above was built with the expression builder.
The field, (Fields!COU_EMA.Value, "CA_Summary"), is a boolean (1 or 0) and I get error either with a 1 or a "true" (no quotes).
I probably could fix it if I knew what the definition of "scope" is. . . maybe.
The scope is where you want to look in order to get the values you're looking for. It could be a data set, group, etc. In your expression it appears CA_Summary is the scope.
I would try modifying the expression a bit. Since you say COU_EMA is bit field, maybe use TRUE. This is also assuming the matrix is using the data set CA_Summary.
=Sum(IIF(Fields!COU_EMA.Value = TRUE, Fields!Amount.Value, 0))
If your matrix isn't using that data set and it still doesn't work try
=Sum(IIF(Fields!COU_EMA.Value = TRUE, Fields!Amount.Value, 0),"CA_Summary")

I have a multi row dataset that I want to do a lookup on and take the bit/Boolean value of one of it's columns and apply it to the hidden property of a tablix.
Here is the expression for the hidden property on the tablix.
= IIF(Lookup(6, Fields!ServiceOfferingID.Value, Fields!UseCustomCalculator.Value, "JobBuyerDetails") = 0, True, False)
If the ServiceOfferingID is 6, get what is in the UseCustomCalculator column to show or hide the tablix.
I don't know if you can compare values like this, what may need to be a string or if they are all just variants.
I have tried converting the values to string with CStr(), putting quotes around the searched value (6 in this case) but have had no luck getting the tablix to show or hide correctly.
There doesn't seem to be a good way to debug this, check what the Lookup is returning etc.
How can I change my expression to get it to work?
What am I missing?
I am pretty new to SQL Server Reporting Services.
I am using SQL Server 2008 R2.
Debugging in the traditional sense isn't really an option. What I normally do is add a textbox and set the expression to the expression you want to test, in your case, set the expression to
=Lookup(6, Fields!ServiceOfferingID.Value, Fields!UseCustomCalculator.Value, "JobBuyerDetails")
and see what you get.
Once you've established what is being returned and corrected the comparison then you can simplify the hidden expression a little.
The hidden expression would just be something like (assuming lookup issues are resolved)
=Lookup(6, Fields!ServiceOfferingID.Value, Fields!UseCustomCalculator.Value, "JobBuyerDetails") = 0
There's no need to use an IIF here as the comparison will return return or false anyway.
I am trying to hide rows in SSRS where Sales values are 0 (zero).
My expression is:
=IIF(Fields!SalesYTD = 0,True,False)
I am getting the error:
"Operator '=' is not Defined for Type Integer..."
How do I implement this logic?
You have a syntax error in your expression. Your error is telling you that SSRS thinks that the position of your = sign is not expected, which usually means you are missing something before it.
In your case, you are missing .Value to tell SSRS that you want the value held within the SalesYTD field as opposed to other attributes.
Consequently, your expression should be:
=IIF(Fields!SalesYTD.Value = 0,True,False)
Try This..
You Just Missed The Value ..
=IIF(Fields!SalesYTD.Value=0, True, False)
I have a rectangle.
I want to hide it if a field (X) is NOT NULL.
I tried this but it is not working:
=IIF(NOT IsNothing(Fields!filepath.Value), 1, 0)
I get the error:
An error occurred during local report processing.
The Hidden expression used in rectangle 'ID2398' returned a data type that is not valid.
Anyone know why I'm having this issue?
Do I need to place the actual field onto the report? I tried it but I keep getting the same error.
If you're using that for the Visibility expression, I believe you need to explicitly use True/False rather than 1 or 0. So try:
=IIF(NOT IsNothing(Fields!filepath.Value), True, False)
I do prefer to use =iff(Fields!filepath.Value IsNot Nothing, Fields!filepath.Value, ) in Textbox/Properties/Visibility/Hide as it is more intuitive for me.
SQL Server 2008 R2, using BIDS to design the report.
I have a table and I am trying to only show a certain row. Maybe there are better ways to do this, but I am coming across an error with the filter expression and regardless of how I achieve my initial task, I'd like to understand the filtering.
I started with the filter expression (set to type "Integer"):
RowNumber(Nothing) = 1
This gave the error:
Cannot compare data of types System.String and System.Int32.
I found the solution to this is to change the 1 to "=1" as 1 is evaluated as a string.
So I then had:
RowNumber(Nothing) = =1
That changed nothing, I got the same error.
Then I tried to do that to the first part of the expression:
=RowNumber(Nothing) = =1
This changed the error to a deployment problem (still builds, which is frustrating):
Error pvInvalidDefinition : The definition of the report '/ReportName' is invalid.
I then tried using CInt on RowNumber:
CInt(RowNumber(Nothing) = =1
Then I can deploy it, but the error just changes back to the first one:
Cannot compare data of types System.String and System.Int32.
It seems no matter what I try here I either can't deploy the report or I get an error that I'm comparing a string to an int.
RowNumber returns an integer, so it seems like this should work. I've tried using the name of the dataset in place of "Nothing" but that doesn't change what I'm seeing.
I realize there are many ways to solve my initial problem, but I am curious as to why the filter expression is invalid.
Its better to hide a row with visibilty property. Just click on any text box and go to visibily tab . You can now click on show or hode and go to expression.
That default to Hide . So write an expression there to hide the row.
=IIf(NOT(RowNumber = 1),TRUE,FALSE)
Let me know if you get any error
RowNumber is not available to use in a Tablix Filter.
Using RowNumber(Nothing) <> 1 as a Row visibility property fixed the issue.
Using BIDS you are not given any error that indicates what the problem is, but importing the report to Report Builder and deploying it from there will give a more descriptive error that, in the end, helped me to solve my problem.
Thank you in advance for taking your time to answer my question.
I am having trouble with expressions in the SSRS reporting system.
The Field I am adding required fields from the dataset I provided in the report, however when I try to preview the report I get the Following message:
"A Value expression used for the report parameter ‘Policies_Total’
refers to a field. Fields cannot be used in report parameter
expressions."
This is my expression:
=IIF(Sum(Fields!policy_id.Value, "DataSet1") Is Null, 0, Count(Sum(Fields!policy_id.Value, "DataSet1")))
That was suppoed to be converted from Crystal reports which has the following expression:
If IsNull ({usp_rep_agent_cases;1.policy_id}) then
0
Else
Count ({usp_rep_agent_cases;1.policy_id})
Any help is much appreciated.
Thank you
I think it may be as simple as understand that a 'parameter' should be passed into SSRS before fields are created for the most part. If this parameter is DEPENDENT on the value of something else first being chosen you cannot list it first as the field is not yet populated to my knowledge. It appears you are trying to use an expression to count something from a field from a dataset when you just make a dataset and reference that field directly. So instead of trying an expression you may choose a few other options instead:
Choose on the left pane of your parameter 'Available Values' selected 'Get values from a query'. You may use your query which is a 'dataset', value is self explanatory, label is what the end user will see display.
The option 'Allow null' value will accept a null value
You may run into situations where multiple datasets may need to be used, multiple selects or querying objects. In my experience with SSRS it gets mad at times when you try to reference a dataset used to display data with a dataset used to determine an event or action. SSRS also gets relativity slower the more Expressions you do so doing a whole report with nothing but expressions versus taking the power of the built ins of the RDL language is not really worth it IMHO.
For SSRS expressions you need to use IsNothing for NULL checking, something like:
=IIF(
IsNothing(Sum(Fields!policy_id.Value, "DataSet1"))
, 0
, Count(Sum(Fields!policy_id.Value, "DataSet1"))
)
In fact the whole expression seems a bit odd; what are you specifically trying to achieve with your expression? Are you just trying to count non-null values?
=Sum(IIf(IsNothing(Fields!policy_id.Value), 1, 0), "DataSet1")
Also, your error seems to be saying that a parameter is referencing a field when this isn't allowed, which may not be solved by changing syntax; I think more information about what you're trying to achieve is required here.
