hi all!
may be you laugh on me but i want to know anyway.
i am using 6i and 10g and wants to know about Hierarchical Tree to populate records like :
1) from emp table which DO NOT HAVE mgr field
2) display data as:
-DEPTNO
-- emp1
-- emp2
-- emp3
-DEPTNO
-- emp1
-- emp2
-DEPTNO
-- emp1
-- emp2
i used - or -- only to make Levels its not required.
please write an SQL statement to populate Hierarchical Tree for above.

Try this:
> break on department;
> Select department, employee from emp_table;
This should give you the output you are looking for. If you want a truly hierarchical query where there is parent and child relationship within table look at connect by clause, connecting the parent to the child.
Good luck. Hope this helps.

Nah, in forms? BREAK? I don't think so.
oralover, try this query in the 'DATA QUERY' property of your tree item:
SELECT -1 state
, DECODE (deptno, NULL, 2, 1) dlevel
, DECODE (deptno, NULL, 'Employee ' || ename, 'Department ' || dname) label
, NULL icon
, DECODE (deptno, NULL, deptno, deptno) DATA
FROM (SELECT DECODE (LAG (d.deptno) OVER (ORDER BY d.deptno), d.deptno, NULL, d.deptno) deptno
, d.dname
, e.ename
, e.empno
FROM emp e, dept d
WHERE d.deptno = e.deptno
ORDER BY d.deptno)
In the small test I ran, it gave the following output:
