Hello All,

Here is the scenario.

Name      CategoryID ParentID
Politics         1              0
Repub.         2              1
Bush            3              2
Democrat     4              1
Clinton         5              4
Cars            6              0
Chevy          7              6
Vette           8              7

It's your basic Parent-Child relationship.  
Politics is the the Parent to Republican and Democrat.
Republican is the parent to Bush
Democrat is the parent to Clinton.

well, I need a stored procedure that, with a given CategoryID, it will return me back a string
representing all of the children that belong to that specified categoryID in one field, in the form of something like,

if i specify Republican with a CategoryID=2 then:
Republican:2||Bush:3

if i specify Politics with a CategoryID=1 i would get returned:
Politics:1||Republican:2||Bush:3||Democrat:4||Clinton:5

One more twist to this would be that if i didn't specify a Category To Search Under,
It would return me back A Row for each Root Category with representation for the Child cateogories for that root. Like for instance,

If Category passed In = 0 then,
return back as many rows as there are root categories, so for the above example would return:

Politics:1||Republican:2||Bush:3||Democrat:4||Clinton:5
Cars:6||Chevy:7||Vette:8


I really don't mind of it's in a ad-hoc query to be put inside of a view, but a stored procedure would suit this type of query best.  Thanks ahead of time for the advice.
