No - you need a single field (column) defined as the primary key to allow VDO to be able to nagivate within the recordset. This is because VDO uses the ADODB Find method to navigate within the recordset and it can only handle single column primary keys.

Generally this isn't an issue because you can usually simply add an autonumber primary key column while still maintaining other a unique index on what might have been your primary key previously.
