Delete numbers and special characters

Delete numbers and special characters

I have a database that I need to clean up and I have to get rid of some characters and other stuff in it.  I have to do it in vbscript so I need a little help.  I can query and return the data fine.  

Here is the problem, I have some entries that are supposed to be last names but because of laziness people have entered some gibberish here is an example.


is there a way to tell that a character is not alpha and how do I remove them?

RE: Delete numbers and special characters

One very low-tech (and slow) solution would be passing each string into this function:


Dim s
s = "Goldberg(#44345)"
s = FixName(s)
wscript.echo s

Function FixName(s)
   Dim ch
   Dim sAcceptableChars
   sAcceptableChars = "abcdefghijklmnopqrstuvwxyz"

   For x = 1 to Len(s)
      ch = mid(s, x, 1)
      If InStr(sAcceptableChars, LCase(ch)) > 0 Then
         FixName = FixName & ch
      End If

End Function

Just add any other characters you want to sAcceptableChars (like a space, or apostrophe maybe).

HOWEVER, this would be much more efficiently solved with Regular Expressions, I'm just not good enough with them to provide an example.

RE: Delete numbers and special characters

Simple RegEx


Option Explicit

Dim arrTemp : arrTemp = Array("NewMan001", "Goldberg(#44345)")
Dim RegEx : Set RegEx = New RegExp
RegEx.Pattern = "[^A-Z]+"
RegEx.IgnoreCase = True
Dim strTemp
For Each strTemp In arrTemp
    WScript.Echo RegEx.Replace(strTemp, "")

RE: Delete numbers and special characters

OK, I have been using this but I have one problem I have some apostrophes ' withing the name, like o'brien, o'tool.  I can I keep the apostrophes in?

RE: Delete numbers and special characters

Just change the pattern

RegEx.Pattern = "[^A-Z']+"
