the information I am looking for is:-
for example:-
level 1:- A
level 2:- B
level 3:- C.

Each employee is assigned to C.

The sql I am looking at is to retrieve A,B,C. So that I can generate a report for A.

can you let me know if I confused you.

Thanks,

Certainly. I assume your tree just has nodes, no detail values/leafs? If this is the case, and you just want to get the structure, the following SQL should work:

SELECT PSTREENODE.SETID,
  PSTREENODE.TREE_NAME,
  PSTREENODE.EFFDT,
  PARENT_NODE_NAME AS PARENTNODE,
  TREE_NODE        AS NODENAME,
  TREE_NODE        AS TREENODE,
  TREE_LEVEL_NUM,
  TREE_NODE_NUM
FROM PSTREENODE
  --- REPLACE WITH YOUR SETID
WHERE PSTREENODE.SETID = 'SHARE'
  --- REPLACE WITH YOUR TREE NAME
AND TREE_NAME = 'ACCOUNT'
  --- REPLACE WITH YOUR TREE EFFECTIVE DATE
AND EFFDT = TO_DATE('01011900','MMDDYYYY')
UNION ALL
--- REPLACE WITH YOUR SETID
SELECT 'SHARE',
  N.TREE_NAME,
  --- REPLACE WITH YOUR TREE EFFECTIVE DATE
  TO_DATE('01011900','MMDDYYYY'),
  N.TREE_NODE AS PARENTNODE,
  ' ',
  ' ',
  TREE_LEVEL_NUM,
  N.TREE_NODE_NUM
FROM PSTREENODE N
  --- REPLACE WITH YOUR TREE NAME
  WHERE TREE_NAME = 'ACCOUNT'
  --- REPLACE WITH YOUR TREE EFFECTIVE DATE
  AND EFFDT = TO_DATE('01011900','MMDDYYYY')
ORDER BY TREE_NODE_NUM,
  TREE_LEVEL_NUM,
  TREENODE;

Let me know if you have any additional questions, or if you were looking for something else. Thanks!
