在SSRS表达式中使用分割

Question

I've value like 100 - XYZ in dropdown list of SSRS Report.

I want to show only XYZ in one of the Textbox.

I've used Split function like below,

=IIF(Parameters!Name.Value <> "",
 "For Name" + Replace(Split(Parameters!Name.Value, "-").GetValue(1)," ", ""),
 "For All Names")

Above example works fine, but when it goes to else case it always throwing error.

Can you please tell me what's wrong with this expression? Or anything wrong with my expression? Especially it is showing red line below (1) but as I said before it is working fine.

Note: I have also tried .GetValue(1) recently but no success.

Answer 1

As Jonnus has mentioned in comment,

It might be showing the error as there is a problem elsewhere in the expression , not just the False part. SSRS evaluates the entire expression before executing it , so if there is a problem anywhere it will throw #Error

I found the alternate solution to achieve my expected result.

=IIF(Parameters!Name.Label = "All",
"For All Names",
"For Name " + Replace(Right(Parameters!Name.Label,
Len(Parameters!Name.Label) - InStr(Parameters!Name.Label, "-"))," ",""))

I tried so many times with Split but I always got failed. If someone has idea to solve this with Split then it would be great. Please share your view. Thanks Jonnus for your quick response.

You appear to be trying to retrieve all the characters after the - in the original string. Rather than doing a SPLIT it would be easier to understand and maintain if you used RIGHT as follows

=iif(Parameters!Name.Value <> "",
 "For Name " & Right(Parameters!Name.Value, 
                     Instr(Parameters!Name.Value, " - ") -1),
 "For All Names")
