CTE For Trees

Hi,

My database looks like:

CategoryID ParentID Title Sort

1 -1 Cars 1
2 1 Honda 1
3 -1 Bikes 2
4 1 Ford 2
5 1 Toyota 3
6 3 Kawasaki 1



How can I retrieve the values in the following order:
1, 2, 4, 5, 3, 6

I have:

WITH MYCTE(categoryID, parentID, Title, Sort)
(
SELECT TOP 1 categoryID, parentID, Title, Sort
FROM Categories
WHERE parentID = -1
ORDER BY Sort ASC

UNION ALL

SELECT c.categoryID, c.parentID, c.title, c.sort
FROM Categories c
INNER JOIN MYCTE cte ON (cte.categoryID = c.parentID)

)

SELECT *
FROM MYCTE


It doesn't seem to work though? Help! hehe
