:23B:CREASDD
:32A:09A1237CHF41912,05
:33B:CHASD1912,05

how can i split this string into new field in such a query by this rule:
bring me all the string after ":20:" Until the next ":", etc
result :
field_:20: =111111251540002D
field_:23B:=CREASDD
field_:32A:=09A1237CHF41912,05
ETC.....

Please provide some more examples of the field content and the table structure that you want to split it into, as it is not completely clear from your example and we don't want to waste time providing a solution that you don't want.

e.g.
Do you want to split the field at every newline (apparently not)
Do you want to split the field at every [newline followed by colon then alphanumeric string then another colon] (yes?)
please clarify: do all examples of this data have the same "field identifiers" (20,23B,32A,33B,50K...)
should the 50k field include everything up to 53A:

I don't know how something this complex could be done in SQL, but it seems a pretty strait-forward solution to simply do some VB code in a loop with the InStr() function and the optional 'start' parameter.  Something like this:
Str = YourBigString
'Find the Start of the 1st Field
P1 = InStr( Str, ":")
Do While P1 > 0
  'Find End of the Next Field
  P2 = InStr(P1+1, Str, ":")
  If P2 = 0 Then
    Exit Do  'String not formated as expected
  End If
  FieldName = "Field_" & Mid$( Str, P1, P2 - P1 + 1 )
  'Find Data
  P1 = P2 + 1
  P2 = InStr( P1, Str, ":" )
  If P2 > 0 Then
    DataStr = Mid$( Str, P1, P2 - P1 ) 'No +1 because the : found starts the next field name
  Else
    DataStr = Mid$( Str, P1 )  'Extracts to end of string
  End If
  'P2 is now the start of the next field name
  P1 = P2 'If no final : found, the while loop will end
  Fields(FieldName).Value = DataStr
Loop

You ciuld use the Split function in VBA to load each line of the string into an array and then address that array in the way you want:

Function SplitString (myString As String) As Single
  Dim myArray() as String
  myArray = Split (myString, vbCrLf)
  SplitString = Ubound(myArray)
End Function

Open in new window


The vbCrLf delimiter would need checking as I can't see what character is used in your example.

Slight tweak to what Jamie suggested to give you what you want:

 Function SplitString (myString As String,intToken as Integer) As String
 
  Dim myArray() as Variant

  myArray = Split (myString,":")
  SplitString = myArray(intToken)

End Function

  Your call would be the string/field with the entire date, and the nth token you want returned from it.

you can simply use a query, f1 is the field that contains the string

select f1, left(f1,instrrev(f1,":")) as result1, mid(f1,instrrev(f1,":")+1) as result2
from yourTable
where instr(f1,":") >0

with this info
:20:111111251540002D

the result will be

f1                                           result1    result2
:20:111111251540002D    :20:          111111251540002D

The following function parses your strings with a regexp object.
Public Function Q_28589320(parmString) As Object
    Dim oRE As Object
    Dim oMatches As Object
    Dim oM As Object
    Dim oSM As Object
    Dim lngSM As Long
    Dim oDic As Object
    
    If oRE Is Nothing Then
        Set oRE = CreateObject("vbscript.regexp")
        oRE.Global = True
        oRE.Pattern = "(:[^:]*:)([^:]*)"
    End If
    
    Set oDic = CreateObject("scripting.dictionary")
    
    If IsNull(parmString) Then
        Set Q_28589320 = oDic
        Exit Function
    End If
    
    If oRE.test(parmString) Then
        Set oMatches = oRE.Execute(parmString)
        For Each oM In oMatches
            With oM
                oDic(.submatches(0)) = .submatches(1)
            End With
        Next
    End If
    Set Q_28589320 = oDic
    Set oDic = Nothing
End Function

Open in new window


I tested the function with the following code:
Sub main()
    Dim strThing As String
    Dim dicThing As Object
    Dim vItem As Variant
    
    strThing = ":20:111111251540002D" & vbCrLf & _
                ":23B:CREASDD" & vbCrLf & _
                ":32A:09A1237CHF41912,05" & vbCrLf & _
                ":33B:CHASD1912,05" & vbCrLf & _
                ":50K:/CH110023412400243526" & vbCrLf & _
                "MSFSDFER KFSFUTDFR" & vbCrLf & _
                "BUDFSFERSTR. 2" & vbCrLf & _
                "8113 BOSDFSFSLSEN" & vbCrLf & _
                ":53A:UBSWCHZH80A" & vbCrLf & _
                ":57D:SFS SDFSDFS" & vbCrLf & _
                "RASDASDA" & vbCrLf & _
                "BRANCH 0" & vbCrLf & _
                "GOGOGOG" & vbCrLf & _
                ":59:/43434" & vbCrLf & _
                "DFSDFL GRSDFOUP" & vbCrLf & _
                "SDFDF + DF LTFDD" & vbCrLf & _
                "DFD HDFDN 343423" & vbCrLf & _
                "GOGOER" & vbCrLf & _
                ":71A:OER"
    Debug.Print strThing
    Debug.Print "==================================="
    
    Set dicThing = Q_28589320(strThing)
    For Each vItem In dicThing
        Debug.Print vItem, dicThing(vItem);

<<that i would like to split into many new fields,and the delimiter should me ->  :numeronly OR numer&Char:>>

  So you can't count on the colon always being there as the start of a new section or was that a typo?   Did you mean to type this:

and the delimiter should me ->  :numeronly: OR :numer&Char:

If you will always have a leading/trailing colon, then use Split().

Token one then will be the code, token two the value for it (you'll have two entries in the array for each element; 1 & 2 first code and value, 3 & 4 second code and value, 5 & 6 third code and value, etc).

Jim.

Nick67 YOU ALmost reach the point, still need small fix :
IN :

ResultID      UglyID      DelimiterValue      UglyText
5      1      :50K:      /CH110023412400243526

in table tblResults , should contain :
UglyText
/CH110023412400243526
 MSFSDFER KFSFUTDFR
 BUDFSFERSTR. 2
 8113 BOSDFSFSLSEN

and not ONLY : /CH110023412400243526
means should contain the string until the next delimiter " :53A:"

Easily enough fixed.
Ugly text just has to be held and concatenated until the next colon is encountered and THEN written to the table.  You need me to fix that, or do you have it cased?
