QueryChainer - adding custom classMethods with complex queries [example]

gistfile1.js

// This is in classMethods:

      a_method: function(id, order_id) {
        var query1 = s.Utils.format(['query goes here...']);
        var query2 = s.Utils.format(['query goes here....']);
        return new s.Utils.CustomEventEmitter(function(emitter) {
            db.query(query1, null, {raw:true}).success(function(row1){
                db.query(query2, null, {raw:true}).success(function(row2){
                    emitter.emit('success', {results1: row1, results2: row2});
                });
            });
        }).run();
      },
