'Connect By' and 'Start With' in Discoverer

Question

Hello,
I have a hierarchal query to show all child organizations under the parameter ':Parent_ID'
This is the query, I execute it in SQL Developer normally:
SELECT el.organization_id_child, ch.name,level*
FROM hr.hr_all_organization_units org,*
hr.PER_ORG_STRUCTURE_ELEMENTS el      ,*
hr.hr_all_organization_units ch*
WHERE el.org_structure_version_id         = 61*
AND org.organization_id                     = el.organization_id_parent*
AND ch.organization_id                      = el.organization_id_child*
START WITH el.organization_id_parent = :Parent_ID*
CONNECT BY el.organization_id_parent = PRIOR el.organization_id_child*
in the below line:
START WITH el.organization_id_parent = :Parent_ID*
The hierarchal query will start with parameter value to show all childes under that organization...
How can I use this simple query in Discoverer !! I am trying to find the START WITH in the discoverer also can not put this query in a new custom folder without removing the parameters.
Please Help...
Regards

Hi,
If you need to use the hierarchical query then you will not be able to pass a Discoverer parameter directly to the start with clause in the custom folder.
However, you can use a database context as a session parameter and use this parameter in the customer folder. More details on this can be found at LearnDiscoverer
Also you could put your hierarchical query into a table function passing the parent_id as a parameter to the table function. Then in your custom view you would join this to a table that returns the list of parent ids that you wish to use. e.g.
select f.organization_id_child, f.name,level
from hr.hr_all_organization_units par
, table (hierarchy_function(par.parent_id) f
where par.organization_id = :parent_id
