I have a hierarchal data structure and the attached code will show a list of all the items linked to their parent. However I want to be able to 'walk' up the table as I will know the id I'm att BUT need to know the id's of it's parent etc upto the root.

Can someone help or explain how to do this. Thanks!
With Breadcrumb( id, parentid, description) as
(
	SELECT id, parentid, Description
	FROM   RadMenu
	--where  parentid IS NOT NULL
)
select parentid, id, description
from breadcrumb
order by parentid

Here's some of the data, filtered to show 1 example:

id      parentid Description
57	NULL	Adaptors
74	57	CompactFlash to IDE
75	57	CompactFlash to SATA
76	57	PCMCIA to CompactFlash
978	57	CFast to SATA
275	74	IDE to 1 CompactFlash Slot 
525	74	IDE to 2 CompactFlash Slots
555	74	IDE to 1 CompactFlash Slot
