How can I use VBA to automatically link via ODBC to a Database and Table from Access 2007?

I am using Access 2007. I have created an ODBC connection. Using the External Data tab I can manually select my ODBC connection and link to a Table in an external database. Is it possible to do the same in VBA so that I can AUTOMATICALLY open the ODBC connection and AUTOMATICALLY link to the Table, or more than one Tables? If you can help with the code and briefly explain what the code does/how it works, that would be very helpful! Thanks. David.

what is your backend db?

Here is an example, depending on your db, it may end up creating schema owners in the tablename.

I think this should do it though. Using ADOX, we make a connection to your ODBC then list tables then connect

Dim adoConn As adodb.Connection
Dim adoRecSet As adodb.Recordset
Dim sSql As String

Set adoConn = New adodb.Connection
adoConn.Open "ODBCDSNName", "USERID", "PASSWORD"

Set adoCat = CreateObject("ADOX.Catalog")
Set adoCat.ActiveConnection = adoConn

For Each adoTbl In adoCat.Tables
DoCmd.TransferDatabase acLink, "ODBC Database", "CONNECTIONSTRING", acTable, adoTbl.Name, adoTbl.Name, False
Next

Set adoCat = Nothing
adoConn.Close

You need to know what your ODBC coinnect string would be, once you know that then you can manipulate the Connect String of a TableDef or even create a new tabledef.

To find the ODNC connect string design the attached table and take a look at the DESCRIPTION property, the DESCRIPTION property will show you the CONNECTION and SOURCETABLENAME properties, the CONNECTION is everything beore ;Tablename=

Private Sub cmdDAOConnectString_Click()
Dim db As DAO.Database
Dim td As DAO.TableDef
 
    Set db = CurrentDb
    
' Change Existing Table
    Set td = db.TableDefs("Example_AttachedTableName")
    td.Connect = "ODBC;DSN=COMPAQ;Trusted_Connection=Yes;APP=2007 Microsoft Office system;DATABASE=EETest"
    td.RefreshLink
    
' Create New Table
    Set td = db.CreateTableDef("Example_AttachedTableName1")
    td.Connect = "ODBC;DSN=COMPAQ;Trusted_Connection=Yes;APP=2007 Microsoft Office system;DATABASE=EETest"
    td.SourceTableName = "tblB"
    db.TableDefs.Append td
    RefreshDatabaseWindow
 
End Sub

Thanks for your quick response. My backend database is SQL Server 2005. I will need a little time to work out my ODBC connect string and try a few things out.

My example is using a DSN to SQL Server with Trusted connections.
