I can't understand the structure of the written code
(CountRows("client_code").Equals(Parameters!client_code.Count)
can anyone explain this please?
And where can I find a reference for all the functions that I can use to write Expression in SSRS??
In SSRS we use "=" operator for comparison rather than equals.
Expression mentioned by you below
(CountRows("client_code").Equals(Parameters!client_code.Count)
Rather it should be like
=IIF(CountRows("client_code")=Parameters!client_code.Count,true,false)
What your mentioned code does: It Returns a count of rows within the specified scope, Scope can be Group as well. and it compared with your Report Parameter count.
Here you will find complete list of functions and expression for SSRS.

I am trying to write an expression in SSRS which counts only specific data using IIF. I found the following solution:
=Sum(IIF(Fields!Program.Value = "FC", Fields!QuantityToShip.Value, 0))
The code above works but only when there is ONE dataset, while I have several.
Here is the code I wrote:
=Count(IIF(Fields!Mgroup.Value,"DataSet1"=303,1,0))
I get the aggregation error:
Textbox refers directly to the field ‘Mgroup’ without specifying a dataset aggregate
I added a sum:
=Count(IIF(Sum(Fields!Mgroup.Value,"DataSet1")=303,1,0))
Still getting the same error.
Why is that?
What can I put instead of Sum? All I need is to count how many groups named 303 I have.
The expression you used has some sintax errors. The Count function only aggregate from the scoped Dataset.
Try this:
=LookupSet(303,Fields!Mgroup.Value,Fields!Mgroup.Value,"DataSet1").Length
Let me know if this helps you.
I am trying to create a footer that is using ProperCase within SSRS 2008
I have tried
=Code.ProperCase(LCase(Fields!aField1.Value, "DataSet1"))
to use the ProperCase field within the footer but it is stating that I do not have the text box linked to a DataSet.
Help would be much appreciated.
I don't think the problem lies with the ProperCase function. However, when inserting a value from a dataset, outside the context of the dataset, you must specify what record to use. For example, to use the first record from the dataset in your page footer, you should write your expression like this:
=Code.ProperCase(LCase(First(Fields!aField1.Value, "DataSet1")))
In other words, the reference to "DataSet1" makes no sense in the LCase-function, which is just a simple string manipulation function. To reference the dataset, you must use one of the Aggregate functions (in this case, First()), which takes as second argument the name of the dataset in question.
I assume you have written the ProperCase function yourself? There is a VBA function available in SSRS that allows you to change the case of a string and it's called StrConv which you could've used.
In your case you'd write: StrConv(First(Fields!aField1.Value, "DataSet1"), vbStrConv.ProperCase)
The other benefit of the StrConv function is that you can specify a localeID too if that is of any relevance.
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.
How to write multiple if statement in SSRS. I have written like this.
=IIf(Parameters!MyDuration.Value="ThisMonth" & Parameters!Transactions.Value="Sale", Sum(Fields!ThisMonthSal), True,False)
this is throwing an exception that multiple parameter used. Please guide me how to write this multiple if statement.
The & operator concatenates two strings. You're looking for the And operator. Refer to this msdn article.
In addition, note that IIF has three parts (see decision functions here), and works like this:
=Iif(test, truepart, falsepart)
I'm not sure what you're trying to do with the "SUM" bit (or what you're trying to achieve at all, the question's not clear on that), but something like this would work:
=IIf(Parameters!MyDuration.Value="ThisMonth" And Parameters!Transactions.Value="Sale",
Iif(Sum(Fields!ThisMonthSal.Value) = 0, "Zero sum", "Non-zero sum"),
"Not thismonth or sale")
Finally, you're not entirely clear about the error you're getting. If you're also having a problem with accessing the parameter you may have to investigate that seperately. In any case, the above should explain the Iif bit.
I am using the following expression in one of my report fields.
=Fields!Value.Value*(Fields!DutyRate.Value/100)
This works as exprected as long as there is a valid value in the Fields!DutyRate.Value.
My problem is that the Fields!DutyRate.Value can contain non numerical values such as "Free".
This means any rows with the word "Free" in them causes an #Error. This is OK as such but I would like to get SSRS to display something other than #Error. In fact I would like to to display "F" instead.
Many thanks
You can use an IIF (inline if statement) and the IsNumeric function.
Syntax: IIF(<condition>,<true part>,<false part>)
=IIF(IsNumeric(Fields!DutyRate.Value),Fields!Value.Value*(Fields!DutyRate.Value/100),"F")
