ORDER BY question.

I have some data that I want to select with an ORDER BY statement and be =
able to have it sorted in a hierrarchical order.
There will be essentially 1) and ID, and 2) a ParentID.
I would like to have the data returned sorted such that any row with a =
ParentID =3D to an ID is under that ID
So if I have:
NAME / ID / ParentID
name1 / 1 / 0
name2 / 2 / 0
name3 / 3 / 1
name4 / 4 / 5
name5 / 5 / 1
name6 / 6 / 2
I want it to come back sorted as:
name1
name3
name5
name4
name2
name6
Any ideas?

Doing what you want to do will require some front-end manipulation.

Here is something similar that might help:

insert into Hi values (7,null,'County 2')
insert into Hi values (8,7,'C2 Region 1')
insert into Hi values (9,1,'C1 Region 3')
select *, 0 as Level, cast(str(pageid,10) as varchar(8000)) as H into #Temp
