I'm trying to pass a report variable to an expression used to populate textbox but it's giving me syntax error. Here's the expression.
=Fields!Variables!col1.Value.Value
The variable (Variables!col1.Value) should return a fieldname that I want to use to populate a textbox inside a table.
Edit:
Basically I have a multi-value parameter that passes on to a stored procedure that pulls the data based on the parameter value. The first 4-5 columns returned are static while the rest are dynamic and can have unknown number of columns but I do know the max number of columns.
What I'm trying to do is to create a fixed number of columns and then show/hide them based on the parameter. I get the column title via an expression (=Parameters!Course_IDs.Label(0)) and then I want to use this value to create a textbox that will populate the column based on this value Course_IDs.Label(0).
Since it is a multi-valued parameter, you will likely need to join the results:
=JOIN(Parameters!ParameterName.Value, ", ")
If it is a variable from the dataset you will likely need to use LOOKUPSET() to get the values.
Also note that parameter values might be ugly to look at. In that case use the name instead - Parameters!ParameterName.Label

I am passing a unique ID as parameter in SSRS report. In the source table, unique id does not contain dashed. However, the user may insert Unique ID including dashes "-" and in some cases without dashes. Is there a way that we could remove dashes from the parameter.
For example, unique id 3120-20268-8 is stored in table as 3120202688. How I could retrieve if user pass multiple values with or without dashes in the SSRS Report.
When is used below query, it gives record against single value only. However, gives error when more than one values are provided.
select * from Table
where Unique_ID in (REPLACE(#Unique_ID,'-',''))
For more than 1 values, it gives errors mentioned below:
The replace function requires 3 argument(s).
Query execution failed for dataset 'ATL_List'.
Thanks
One of the simplest mechanisms for this is to create an expression based parameter to hold the sanitised input. This parameter would be hidden so the user is not aware of it, but the rest of the usage of the parameter is the same.
NOTE: You could do something similar with a query based default value, but this case is easier to do via a simple expression
Single Value Parameter
Create a new parameter:
set it to hidden
Set the default value expression:
=Str(Parameters!inputID.Value).Replace("-","")
Multi-Value Parameter
This is only slightly trickier, in the expression we can join the selected values together into a CSV string, then process that value and then split it back:
Set the parameter to multi-value, but still hidden:
Set the default value expression:
=Join(Parameters!inputID.Value,",").Replace("-","").Split(",")
Without going to detailed, if we made the sanitised parameter temporarily visible, just to demonstrate the conversion, it should look like this:
The parameter MUST be hidden!
NOTE: DO NOT make your sanitised parameter visible as in the above screenshot in your deployed report! Doing so will mean that it will not pickup changes made to the input value after it has rendered the first time.
remember that we have exploited the default value, we haven't arbitrarily defined en expression to always execute.
The output when the parameter is hidden is calculated when the report is rendered, it's just harder to visualise the behavior in this static post:
In your DataSet query you would just use the sanitised parameter:
SELECT * FROM Table WHERE Unique_ID IN (#sanitisedMultiValue)
You should be able to use the replace function in your report to format the parameter value after it has been entered, something like the below
replace(Fields!Paramater.Value,"-","")=FieldinYourTable
So I have a multiple value parameter than contains 3 options. >250K, <250K, >2M.
I also have a table that consists of multiple columns.
. Because the parameter is a multivalue, i am having difficulties filtering the dataset.
I need to filter the dataset by checking, (if > 250K is selected, filter the dataset accordingly), (if < 250K is selected, filter the dataset accordingly) and (if > 2M is selected, filter the dataset accordingly).
I was told to use a join and split on the parameter within the (>250K condition, then do a contains to see if it contains any of the parameter values) but I am not as advanced in my knowledge of coding to be able to do that.
Any Suggestion? Thanks in Advance
I previously tried the method below but then i came to realise that it wont work because the parameter is a multi value.
I know its been a while since you raised this, you were on the right track but all you should need to do is add a filter to the Tablix on the field you will be filtering, use the 'in' operator and in the Value type [#Yourparametername] the square brackets and case sensitivity are important. Also ensure the expression type is correct, in your case it looks like you are using Integer. The image should help.
If you want to use multi-parameters, In the dataset, you can read parameter value using JOIN.
Example:
If you want to read multiple values for #MyParamter in a dataset given in the following example:
Dataset Parameters
you need to use =JOIN(Parameters!myMultiParamter.Value,",") as an expression to read all selected values in CSV form.
Expression
Now the #ParameterValues param has all selected values as comma separated values and you can use them in your dataset code as per design requirements.
Note: It's not necessary to use a comma but u can use anything you want to separate values.
Your sql query where should look like
Where
(
(0 IN (#Parameter) AND ValueColumn<250000)
OR
(1 IN (#Parameter) AND ValueColumn>=250000)
OR
(2 IN (#Parameter) AND ValueColumn>=2000000)
)
One parameter
Two parameters
All parameters
Once you return the value you can also use charindex or patindex* and look for where the value in your where clause is a pattern where the index number is > 0 . For instance if the returned string from SSRS is '01,02,03' and then your where clause has something like this right(field, 2) which would result in value '03'. you change your where clause to be where patindex('%' + right(field, 2) + '%', #returnedstring) > 0 which will give you results. The keeps you from having to parse apart the #returnedstring parameter in your sql code.
I'm trying to create an expression with a missing column. as in the column is not returned from the query but does exist in the list of fields.
The problem I'm having is that every time I do an expression and one of the parameters is from a field that doesn't have a return from query the query fails silently. the following example is looking at a field "test" that, as I said, exists in the list of fields but is not returned from the query, how can I have this is statement send "alert"??
=IIF(Fields!test.IsMissing,"alert",Fields!test.Value)
The reason that I don't return the field is that the columns are dependent on the parameters I enter in the procedure (so they could be used or not depending on what the user is asking)
Thank you
From reading your question I think, you have dynamic columns which will be returns conditionally
So what you should do is,
1) Create the parameter in the parameter list and set it as the internal and assign the field value to that parameter, suppose the parameter is dyanmicfiledvalue
2) Change your expression as,
=IIF(IsNothing(Parameters!dyanmicfiledvalue.value),"alert", Parameters!dyanmicfiledvalue.value )
that should do it. Let me know in case of issues.
Or if you want to check null or empty value for that column just change as
=IIF(IsNothing(Fields!test.value),"alert",Fields!test.value)
I have multi Valued Parameter which have list of values in the Drop down .
I am trying to apply filter on the data set.My requirement is when i choose a value from Drop down,it should be filtered on that value.
I am using the below value in my DATA SET Filters
=join(Parameters!TierStatus.Value,",")
But i am getting an Error like
"Failed to evaluate the FilterValues of the Dataset"
How can write a filter expression based on the multi valued parameter
If you are using "IN" as the operator, you should be able to simply put your parameter in the Value field (do not use the JOIN function).

I have a data set that is returning two properties, a name and a total units. I am trying to set an iif expression on a data bar where iif(field!Name.Value = "Name", field!Total.Value, 0)
this is not working I get an error of rsFieldReferanceAmbiguous, the fields refers without specifying a dataset aggregate. And the only option that it gives me as an aggregation is First, but I do not want to get the first name, I want the bar to display the total units base on the name field that is in the iif expression.
rsFieldReferenceAmbiguous refers to trying to match something that is not in local scope. Therefore you have to aggregate it. You are probably wanting something like this:
=Sum(IIF(Fields!Name.Value = "Name", Fields!Total.Value, 0))
The function you are trying to use would be better suited to a calculated field in your dataset. Then you can just refer that that field in your report. This allows you to filter the data line by line instead of by groups.
Right-click on the dataset and go to Dataset Properties.
Go to Fields.
Click Add then Calculated Fields.
Enter the name of the field and then the expression here.
Make sure your tablix has the dataset specified under General -> DataSetName on the properties pane. If you have more than one data set on the report you will need to specify which data set your reffering to like so:
(Fields!Name.Value, "NameDataSet")
If your useing tables you may need to ckeck if you have grouping and if so how your grouping your data.
