Question

I hava a Pass-Through sql-query in access which queries my mysql-db.

My current ODBC connection for the query is defined as follows:

ODBC;UID=access_frontend; PWD=hello@world; DSN=my_db_test;

If I change my ODBC connection from my test to my normal DB

ODBC;UID=access_frontend; PWD=hello@world; DSN=my_db;

If I save my changes and restart again, Access has changed it back to my_db_test.

Is there any place where I can globally change my ODBC connection?`

I do not get this problem changing in code or manually. You can change the connection through VBA:

Dim qdf As QueryDef
''dbQSQLPassThrough = 112
For Each qdf In CurrentDb.QueryDefs
    If qdf.Type = dbQSQLPassThrough Then
        Debug.Print qdf.connect
        qdf.connect = "ODBC;filedsn=z:\docs\test.dsn;"
        Debug.Print qdf.connect
    End If
Next

You will notice that the passthrough query illustrated refers to:

filedsn=z:\docs\test.dsn;

This is another easy way of changing the connection, just change the DSN, in the above case, you could just edit the file test.dsn.
