Most of the records in the report in the field VOID are nulls (no display)
I do not know where to begin, so there is nothing to show that i have tried.
How do i present a summary count of records in the report that are not nulls?
Assuming a few things...
The VOID field is text.
The "nulls" are against each record and not the result of a
matrix/pivot where in fact no record exists in your dataset.
You Dataset is called myDataSet
To count all the null or empty instances you can use something like this
=SUM(IIF(LEN(TRIM(Fields!VOID.Value)) > 0 , 1, 0), "myDataSet")
This takes the content of the VOID field, TRIMs it (this will remove spaces, it's all spaces it will return an empty string). Then be check the LEN of this. If it's not zero then return 1, else return 0. Then SUM all the results within the scope of the dataset called myDataSet

I'm trying to modify a report that uses a multi value parameter (a|b|c|d). That parameter is split into multiple columns. The expression on the first column is =Split(Fields!AlternateVendorDetails.Value.ToString(),"|")(0). If that field is blank in the query, the field in the column is blank, which is right. However, the other columns evaluate to an error (=Split(Fields!AlternateVendorDetails.Value.ToString(),"|")(1)). I've tried =IIF(Fields!AlternateVendorDetails.Value.ToString()='','',Split(Fields!AlternateVendorDetails.Value.ToString(),"|")(1)), and I'm not sure what else will work.
SSRS evaluates expressions even when using Iif conditions and that causes the error.
You need custom code to overcome the limitation.
You can create a function that takes the string, the delimiter and array item index, and returns the value if string is not empty and value index exists
Public Function GetArrayItem( s As String, d As String, i As Integer) As String
If s = "" Or Split(s, d).Length < i+1 Then
Return Nothing
Else
Return Split(s, d)(i)
End If
End Function
I ended up putting a COALESCE(value1 | value2 | value3,' | | ') in the query. That created the necessary fillers to set the values to blank.
need to pass one column in Lookupset and I am doing as below
="Billing Code: "+Code.JoinDistinct(LookupSet(Fields!BillingCode.Value, Fields!BillingCode.Value, Fields!BillingCode.Value, "DataSet1"),",")
and the Function is
public shared function JoinDistinct(
dups as object(),
delimiter as string
) as string
dim result as string = ""
system.array.sort(dups)
for i as integer = 0 to dups.length - 1
if i <> 0 then result += delimiter
if i = 0 orElse dups(i) <> dups(i-1) then result += dups(i)
next i
return result
end function
Result
Billing Code: ,,,A,,,,,,
How Can I remove extra commas
What you're trying to do is certainly possible, but requires a bit of a workaround. The Join function is designed to work on an array of values. The column you used, even though it may have multiple rows at that scope, is not an array. You can use the LookupSet function to get the rows as an array and pass them into the Join function. If there may be duplicate values that you want to remove, you'll have to add custom code to handle that.
Here's an example of how to do that: https://stackoverflow.com/a/27141955/2033717
Let me know if this answers your question.
I got a little problem with Lookupset on a SSRS Report.
The report has a father-child structure in the group section and the datasets come from different tabular.
The problem occurs when one of the Product from Dataset1 is missing on Dataset2, the entire sum returns 0.
I tried this VB code in order to sum up all the values the Lookupset is able to return.
Function SumLookup(ByVal items As Object()) As Decimal
If items Is Nothing Then
Return Nothing
End If
Dim suma As Decimal = New Decimal()
suma = 0
For Each item As Object In items
suma += Convert.ToDecimal(item)
Next
Return suma
End Function
I expected the sum of every Product Lookupset is able to retrurn me but it is just returning 0 if one of the Products is missing in Dataset2.
Is there a way to manage the Nothing returned by Lookupset?
Sorry for the formatting and my poor english and thanks in advance!
I would handle this by checking for the value in your LOOKUPSET expression that SumLookup is summing.
I assume that your expression looks something like this:
=CODE.SumLookup(LookupSet(Fields!ProductID.Value,
Fields!ProductID.Value,
Fields!Price.value,
"Dataset2") )
Use an IIF with ISNOTHING to check for the NULL values and set them to zero:
=CODE.SumLookup(LookupSet(Fields!ProductID.Value,
Fields!ProductID.Value,
IIF(ISNOTHING(Fields!Price.value), 0.00, Fields!Price.value),
"Dataset2") )
The function returns a Decimal datatype. By a Decimal datatype Nothing and 0 are the same. You can test this.
Put a tablix into your report with year from 2017 to 2019. Then put the year in a column of the tablix as a number format, then write the following expression in the detail textbox:
=CDec(IIF(CDec(Fields!Year.Value) = 2017, 0, Nothing))
After executing your report you will notice that every value in the year column is 0.
The same goes for the check. Both of these expressions will always return Yes. I basically check for 0 and the second one for for Nothing:
=IIF(CDec(IIF(CDec(Fields!Jahr.Value) = 2017, 0, Nothing)) = 0, "Yes", "No")
=IIF(CDec(IIF(CDec(Fields!Jahr.Value) = 2017, 0, Nothing)) = Nothing, "Yes", "No")
But remember your textbox/column has the be a number format.
So if you want to return Nothing and you display it in a number format textbox, it will show you a 0.
I'm trying to obtain a list of the different field values within an SSRS Report, and then display the result set on the page header.
See link below for an example.
I know that usually this would be completed simply with groups but the user does not want the Tasks split out.
Thanks
Example Report:
To get the unique values into a single cell, you will need to utilize the code behind functionality in SSRS.
Click on the background of your report and go to report properties -> Code. Paste this function into the window:
Public Shared Function RemoveDuplicates(ByVal items As Object()) As String()
System.Array.Sort(items)
Dim k As Integer = 0
For i As Integer = 0 To items.Length - 1
If i > 0 AndAlso items(i).Equals(items(i - 1)) Then
Continue For
End If
items(k) = items(i)
k += 1
Next
Dim unique As String = New [String](k - 1) {}
System.Array.Copy(items, 0, unique, 0, k)
Return unique
End Function
In the expression in your table where you want the unique values list, insert this expression:
=Join(Code.RemoveDuplicates(LookupSet(1,1, Fields!ID.Value, "DataSet1")), ",")
"Fields!ID.Value" is a reference to the field in your dataset that you want unique values from.
"DataSet1" is the name of the dataset that your field is located in.
What happens is that at runtime, the entire set of values from your query column are passed to the VB function which uses returns an array of unique values. The expression in the report Joins the unique array values back together with a comma deliminator.
I have a table in ssrs 2008. This table has a row visibility expression like:
=IIF(max(Fields!VExpected.Value) <> "", 1, 0) +
IIF(max(Fields!MExpected.Value) <> "", 1, 0) +
IIF(max(Fields!PExpected.Value) <> "", 1, 0) = 3, false, true)
Sometimes the datasource returns no data, or the returned data is not matching with this expression. In this case what I see is that a table with borders and column names but no data on it like:
id Vex Mex Pex
However, I want to show it as
id Vex Mex Pex
- - - -
Or if possible:
id Vex Mex Pex
No Data
Another question is, is there any way to hide the complete table if there is no returning data or any matching data with the expression?
Thanks
You can use CountRows function to determine how many rows your dataset is returning. If it is zero hide the table otherwise show it.
=iif(CountRows("DataSetName")=0,true,false)
Replace DataSetName by the actual name of your dataset.
For not matching expression data you can use the this expression.
=IIF(
max(Fields!VExpected.Value) <> "" AND
max(Fields!MExpected.Value) <> "" AND
max(Fields!PExpected.Value) <> "",False,True
)
The whole expression for matching expression and no rows cases could be something like this:
=Switch(
CountRows("DataSetName")=0,true,
max(Fields!VExpected.Value) = "",true,
max(Fields!MExpected.Value) = "",true,
max(Fields!PExpected.Value) = "",True,
true,False
)
Supposing VM, ME and PE expected values are numeric type I'd use ISNOTHING() function to determine when null values are being returned.
=Switch(
CountRows("DataSetName")=0,true,
ISNOTHING(max(Fields!VExpected.Value)),true,
ISNOTHING(max(Fields!MExpected.Value)),true,
ISNOTHING(max(Fields!PExpected.Value)),True,
true,False
)
Additional you can set a message when no rows are being returned from your dataset. Select the tablix and press F4 to see properties window. Go to NoRowsMessage property and use an expression to say your users there is no data.
="There is no data."
In this cases the tablix will not appear in your report but the message you set will be rendered in the location where the tablix should be.
Let me know if this helps.
