Question

We have orders and RMA's. RMA's can be created with order_products of an order. If in the RMA a new product is send, the product can also be added to a new RMA, and so on.
Now for example, I have this schematic structure of an order with RMA orders.
Order (1)
|-> RMA (2)
|-> RMA (3)
|-> RMA (4)
|-> RMA (5)
Now I want to traverse up from RMA (5), all the way up. So actually I want to get 5 records from the database containing all the RMA's and the original order (All from the order table). How can I do this, given the database structure shown below.
Here is a SQLFiddle.
CREATE TABLE `order` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`type` varchar(5) DEFAULT NULL,
`description` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
CREATE TABLE `order_product` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`order_id` int(11) DEFAULT NULL,
`description` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=utf8;
CREATE TABLE `order_rma_product` (
`id` int(11) unsigned NOT NULL AUTO_INCREMENT,
`order_id` int(11) DEFAULT NULL,
`order_product_id` int(11) DEFAULT NULL,
`description` varchar(255) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
INSERT INTO `order` (`id`, `type`, `description`)
VALUES
(1, 'order', 'Original order'),
(2, 'rma', 'RMA of order 1'),
(3, 'rma', 'RMA of order 2'),
(4, 'rma', 'RMA of order 3'),
(5, 'rma', 'RMA of order 4');
INSERT INTO `order_product` (`id`, `order_id`, `description`)
VALUES
(1, 1, 'Product'),
(2, 2, 'Product'),
(3, 3, 'Product'),
(4, 4, 'Product');
INSERT INTO `order_rma_product` (`id`, `order_id`, `order_product_id`, `description`)
VALUES
(1, 2, 1, 'Return product'),
(2, 3, 2, 'Return product'),
(3, 4, 3, 'Return product'),
(4, 5, 4, 'Return product');
I have tried this, but this give's me one row, so i tried contact_ws to get them all in on column. But this only works for the given set of JOINS, so not unlimited going up.
SELECT CONCAT_WS(',', op.order_id, op1.order_id, op2.order_id)
FROM `order` o
JOIN order_rma_product orp ON o.id = orp.order_id
JOIN order_product op ON orp.order_product_id = op.id
JOIN order_rma_product orp1 ON op.order_id = orp1.order_id
JOIN order_product op1 ON orp1.order_product_id = op1.id
JOIN order_rma_product orp2 ON op1.order_id = orp2.order_id
JOIN order_product op2 ON orp2.order_product_id = op2.id
WHERE o.id = '5';
