摆脱任何括号或括号SSRS中包含的值

Question

I'm trying to remove any parenthesis or value enclosed in parenthesis in a string field in SSRS, which will be the best way to do it? I read about replace function but not sure how to use it with several values.

Here are some examples about what I'm trying to do:

Original string    Expected string
ERP(123)           ERP
TE(PO)ST           TEST
(123)string        string

Answer 1

Assuming you only have a single set of parentheses then this will work.

=LEFT(Fields!test.Value, InStr(Fields!test.Value, "(") -1)
&
MID(Fields!test.Value, InStr(Fields!test.Value, ")") +1)

Basically we take the left part of the string up to the first "(" position minus 1 and then concatenate the remainder of the string starting at the first ") +1

Answer 2

For this I would use a function that would be usable everywhere and not always copy paste:

In here we do a Substring of the part we want to delete, and then we do a Replace to changed with no spaces and that way the string will be together (in the case if the original was separated by the parenthesis)

Public Function removeParenthesis (input As Object) As Object
    Try
        Dim FirstIndex As Integer = input.IndexOf("(")
        Dim SecondIndex As Integer = input.IndexOf(")") - FirstIndex + 1
        Dim Result As String = input.ToString().Replace(input.Substring(FirstIndex, SecondIndex), "")
        Return Result
    Catch ex As Exception
        Return ex
    End Try
End Function

This is pasted in the Code sections and will be called like this:

Code.removeParenthesis(Fields!Textbox1.Value)

The function is implemented on Report > Report Properties > Code > paste the function above

EDIT Taking in mind what @Alan Schofield said in his answer

Assuming you only have a single set of parentheses [...].

I have made a little change and have validate too if there's actually some parenthesis, the idea is to loop till everything is clean.

If there's no parenthesis then It'll return original value

Public Function removeParenthesis(input As Object) As Object
        Try
            Dim Result As String = input.ToString()
            Dim FirstIndex As Integer = Result.IndexOf("(")
            Dim SecondIndex As Integer = Result.IndexOf(")")
            While FirstIndex <> -1 And SecondIndex <> -1
                SecondIndex = SecondIndex - FirstIndex + 1
                Result = Result.Replace(Result.Substring(FirstIndex, SecondIndex), "")
                FirstIndex = Result.IndexOf("(")
                SecondIndex = Result.IndexOf(")")
            End While

            Return Result
        Catch ex As Exception
            Return ex
        End Try
    End Function
