Im using the query like as
pergrpid := 791.
WITH T AS
(select mas.menu_id,
mas.menu_name,
mas.url,
mas.apex_page_no,
mas.menu_parent_id,
mas.rank,
mas.menu_level
from sfa_menu_master mas
where mas.enabled_flag = 'Y'
and nvl(mas.delete_flag, 'N') = 'N'
connect by prior mas.menu_id = mas.menu_parent_id
start with menu_id in
(select menu_id
from sfa_menu_roles rol
where (rol.role in
(select max(role)
from sfa_per_groups grp
where grp.per_group_id = pergrpid) or
rol.region in
(select region
from sfa_per_groups grp
where grp.per_group_id = pergrpid) or rol.region = null or
rol.person_id = null))
order siblings by rank)
select * from t;
but i want to check role , region ,segment , personid,
if i give role,region, segment mean i want to check three conditions
if i give only role and region mean want to check that 2 conditions only
if i give role alone mean i have to check 1 conditions alone
if i give personid mean i have to check personid
awaiting for the reply.
Thanks in Advance,

Answer 1

A "parent" without a child will not show up as a parent, but it may show up as a child.
When that happens, CONNECT_BY_ISLEAF will be 1.
So, filter on CONNECT_BY_ISLEAF = 0.select empno, ename, job, mgr from scott.emp
where connect_by_isleaf = 0
start with mgr is null
connect by mgr = prior empno;
