Adding autonumber field to table (1 Viewer)

[CuriousGeorge]

Is there an easy way to insert an autonumber field into a table? Just so every row gets indexed from 1 to n so that i can use that field to sort my queries?

My first idea was to add an extra field in the import specification but i cant find the datatype 'autonumber' there.

ANy help is appreciated,

Pasting my import routine:

Private Sub Command0_Click()
If MsgBox("This will open the folder for imports. Continue?", vbYesNoCancel) = vbYes Then
Debug.Print s
Shell ("C:\Users\SSS787\exjobb\Database\Readlog_update\readlog.exe " & Me.TextPath & "\*.*")
 
 
Dim i As Integer
Dim tblStr As String
Dim varItem As Variant
Dim specname As String
Dim sFile As String
Dim n As Integer
 
i = 1
tblStr = ""
specname = "Import Specs"
n = 0
 
    With Application.FileDialog(msoFileDialogFilePicker)
 
        With .Filters
            .Clear
            .Add "All Files", "*.*"
        End With
 
             .AllowMultiSelect = True
             .InitialFileName = Me.TextPath
             .InitialView = msoFileDialogViewDetails
                    If .Show Then
                      For Each varItem In .SelectedItems
 
                        For i = 1 To Len(varItem)
                          If IsNumeric(Mid(CStr(varItem), i, 1)) Then
                            tblStr = tblStr & Mid(CStr(varItem), i, 1)
                          End If
                        Next i
                        If Right(CStr(varItem), 4) = ".txt" Then
 
                          DoCmd.TransferText acImportDelim, specname, "TableData", CStr(varItem), True
                            i = i + 1
                              DoCmd.OpenTable "TableData", acViewNormal, acReadOnly
                                  DoCmd.Close
                                    tblStr = ""
 
                        End If
 
 
 
                            sFile = ParseFileName(CStr(varItem))
 
                            CurrentDb.Execute "UPDATE TableData SET BananaField = '" & sFile & "'  WHERE BananaField Is Null;"
 
 
                    Next varItem
 
 
                      MsgBox "Data Transferred Successfully!"
                    DoCmd.Close
                    End If
      End With
  End If
 
End Sub

Hi George,
in case you work with access you will find in the design view of the tabe under datatype the AutoNumber. this function automatically numbers your data set.

 

[gemma-the-husky]

but an autonumber won't really maintain a sequence. what happens if you add a record that should interleave between two existing records.

if the order of insertion IS relevant, just add a field for date/time inserted and then you will have real useful data, rather than a meaningless number.

There OUGHT to be some other information in your table to enable you to sort it into any order you like.
