how to using IN operator in ssrs expression

问题

First of all sorry about my english. I want to use in ssrs in tablix-fields expresion something like this:

=iif(CStr(Fields!Id.Value) in Split(Parameters!IdListStr.Value, ","), Fields!Sum, "")

where Parameters!IdListStr.Value = "1,2,3".

is it possible?

回答1:

You can add the filter on the dataset using the below values,

 Expression := Fields!Id.Value
 Operator := In
 Value:= Split(Parameters!IdListStr.Value, ",")

And if you dont want to filter out the records from the dataset then you an use the below expression

= IIF(Array.IndexOf(Parameters!IdListStr.Value, Fields!Id.Value) > -1,Fields!Sum.Value,Nothing)
