Hi,
I've been through with that lately, modify this to see how it helps.
SELECT LPAD(' ',5*(LEVEL-1)) ||name|| ' empno:'||emp_no ||' '||'works
for: '||functional_mgr_name
FROM HRTABLE
where functional_mgr_badge =&emp_no
START WITH emp_no= &emp_no
CONNECT BY PRIOR emp_no = functional_mgr_badge

Oracle has a very good section on "prior" and "connect by".
These combined "level" let you walk a tree - so to speak.
I use them all the time. Look up the key words. You'll find it.

Hi,
I am stumped on how to do a particular hierarchical
query. The query needs to be written entirely in SQL.
I have a table (ACCOUNT) with 3 columns of interest in
it, ACCOUNT_ID, ROOT_ID, PARENT_ID. Every row
represents an account. If an account is the "root"
(top-most), then the ROOT_ID and PARENT_ID columns are
null. If an account is a "parent", then the ROOT_ID is
populated but the PARENT_ID is null. Accounts can be
nested multiple levels deep.
I need to find all of the accounts that belong to the
root of the given account but not include any accounts
that are children of the given account. Does this make
sense?
I.e. 5
6 7
8 9 10
11 12 13 14
I'm not sure if my tree diagram will be dispalyed
properly after I email this but in essence if "8" is
the given account number, I want everything returned
except for 8, 11 and 12.
Thanks in advance!
