[ms-access] Access VBA | How to replace parts of a string with another string

You could use a function similar to this also, it would allow you to add in different cases where you would like to change values:

Public Function strReplace(varValue As Variant) as Variant

    Select Case varValue

        Case "Avenue"
            strReplace = "Ave"

        Case "North"
            strReplace = "N"

        Case Else
            strReplace = varValue

    End Select

End Function

Then your SQL would read something like:

SELECT strReplace(Address) As Add FROM Tablename
