Answer 1

I recommend you use Async

router.post('/', function(req, res) {
    var order_id = req.body.order_id;
    var user_id  = req.body.user_id;
    var table_id = '';

    mongo.connect(url, table_id, function(err, db) {
        myFuntion(db, table_id, function(result) {
            res.send(JSON.stringify(result)); // it should be what you need
        })
    })

});

function myFuntion(db, table_id, callback) {
    var result = [];
    async.waterfall([
        function(callback) {

            db.collection('tables').update({id: table_id, status: true}, {$set: {status: false}}, function(err, result) {
                assert.equal(null, err);
                callback(null);
            });

        }, function(callback) {
            db.collection('tables').find({status: false}, function(err, docs) {
                docs.forEach(function(doc) {
                    result.push(doc);
                })
                callback(null, result);
            });
        }
    ], function(err, result) {
        callback(result);
    })

}
