'Course it's been awhile since I looked at DBDO's design, but seems like either of these would be pretty straightforward to implement.

This is an interesting idea, Alan, any thoughts?

BTW, DB_DataObject_FormBuilder does exactly this kind of thing in its processForm method. After looking at how others do it, what about something like this:

function replaceInto() {

       // This should call the replaceInto directly to the DB if it is
       // supported; otherwise use the following logic:
             // Determine if keys are set
       $update = 0;
       $keys = $this->keys();
       foreach($keys as $k => $v) {
           if (!isset($this->$k)) {
               $update++;
           }
       }
             // Determine whether to call update or insert
       if ($update == count($keys)) {
           $this->update();
       } elseif ($update) {
           $this->raiseError("replaceInto: Not all keys are defined",
                             DB_DATAOBJECT_ERROR_NODATA);
       } else {
           $this->insert();
       }
                 }
