If you have added dummy field in render_sql, it can be done in next way 

function fixDummyField($action){
        $action->remove_field("dummy"); //dummy field will be ignore in saving operations
};
$grid->event->attach("beforeProcessing","fixDummyField");
$grid->render_sql("select *, 0 as dummy from table","id","a,b,dummy,c");
