Create user menus in hierarical tree with access control

Question

Hi All,
I am facing problem in populating user menus in hirarical against user access control.
I have table of menus in which i populate data as:
Menu
- Sub Menu 1
-- Form 1
-- Form 2
-- Form 3
- Sub Menu 2
-- Form 4
-- Form 5
-- Form 6
Now I have created hierarical query as:
SELECT -1, LEVEL, menu_name, NULL, id
FROM menu_opt
START WITH parent_id IS NULL
CONNECT BY PRIOR menu_id = parent_id
and menu_id in
(3, 4);
Note: where menu_id 3 = Form 1, Menu_id 4 = Form 2.
If I allow only menu ID 3 and 4 (not parents menus) then Hierarchy should be completed from top to bottom. What change i have to made to achieve my target?
Thankx

Hi,
Sorry, it's very unclear what you want to do.
Whenever you have a problem, please post CREATE TABLE and INSERT statements for a little sample data, and the results you want from that sample data.
Say which version of Oracle you're using, e.g. 11.2.0.2.0. This is always important, but especially so with CONNECT BY queries, because every version since Oracle 7 has had significant improvements in this area.
See the forum FAQ {message:id=9360002}
If you can show the problem using commonly available tables (such as scott.emp or hr.employees, both of which contain trees) then you don't need to post any sample data; just the results you want and an explanation of how you get those results.
For example, I think you're asking something like this:
"I want to show the hierarchy in scott.emp, but I only want to show certain nodes and their descendants. For example, if I ask for 'MILLER' and 'SCOTT', I would want to see
{code}
` EMPNO ENAME
7876 ADAMS
7788 SCOTT
7934 MILLER
{code}
(order doesn't matter). ADAMS is included because ADAMS is a child of SCOTT."
Here's one way to do that:
SELECT DISTINCT
     empno, ename
FROM     scott.emp
START WITH     ename     IN ('MILLER', 'SCOTT')
CONNECT BY     mgr     = PRIOR empno
;This query should work in any version of Oracle.
