Access97 Pass-through-Query

I wish to use a pass-through-query in Access97 to speed up retrieving a recordset from an SQL server.

I can setup the parameters for the ODBC Connection String by opening up Properties for the pass-through-query in Access97.

Question is, how do I open the pass-through-query and programatically supply the ODBC Connection String needed to connect to the SQL server?

High points for a speedy answer!

Public Function GetQueryLinks()

On Error GoTo Err_GetQueryLinks

    Dim qdf As DAO.QueryDef
    
    For Each qdf In CurrentDb.QueryDefs
        If qdf.Connect <> "" Then
            Debug.Print qdf.Connect
        End If
    Next
    
Exit_GetQueryLinks:
    Set qdf = Nothing
    Exit Function

Err_GetQueryLinks:
    MsgBox Err.Number & " (" & Err.Description & ") in procedure GetQueryLinks of Module basTableLinks"
    Resume Exit_GetQueryLinks

End Function

Open in new window

This public function will retrieve the connection string for your pass-through queries.  A simple modification to then change/update the connection string.

qdf.Connect = "the new connection string"
qdf.RefreshLink

Thanks OM Gang.
I have Access97 and the command qdf.RefreshLink is not valid.
Any thoughts?
Thanks!

Try qdf.Refresh
Let me know if it still doesn't work.

There is no QueryDef.Refresh

however,

QueryDefs.Refresh is valid.

Does CurrentDb.QueryDefs.Refresh successfully update the connection string for the pass-through query?

I tried it in Access 2007 and it works - the pass-through connection string is updated.
