Am going to try to pick up a copy of Celko's book.
Not sure how, but I think I have something that works:
Had to include a column in the table called level, which then
Good point. We're still using 4.5. Unlucky us.

Jason,
It looks like you're using Oracle, and if so, you don't need to have a
"level" column in the table, as level is a psuedo-column available to you
when you use connect by...prior. However, you'll discover that using connect
by...prior only works if your data in the table is already correctly
Anyone care to work on porting these stored procedures to Oracle? I'm
willing to work on it, but would love some help.

Jason,
NTM is the better method, but if you're looking for a quick and dirty
solution then write yourself a recursive tag. Just be careful not to get
stuck in a loop and bring your server down tho. ;o)
What you do is write a tag that you can pass a parent ID to.
In the tag you :

Hey Jeremy,
While pulling data out of the nested set model is easy, getting it in is not
so easy. Care to throw out some examples of that?

One way is to write an SP and in it you create a temp table (#temp in this
example) with one field called ID then..
-- Insert initial records
INSERT INTO #Temp (ID)
SELECT ID FROM table WHERE Boss = @ID
--Insert all terms further down the heirarchy
DECLARE @rowcount int
, @rowcount1 in
Jason,
You've got the right idea, but I would recommend you make John's boss be 0,
since he would be the top of the chain. Then all you have to do is make your
query and group by ID and Boss. You can easily show all the data using
cfoutput or you can use cftree.

Hi,
What you are trying to do is a very common
situation. The Child-Parent model is a workable
solution.
You might really want to take a look at the
Nested Set Model (or NTM, Nested Tree Model). The
NTM model uses a different approach to establishing
hierarchies.
