Hi
we have foll columns ina out PBANk table
pbankname pbankparentcode pbankcode
aaa -1 101
bbb 101 201
ccc 101 202
ddd 101 203
eee -1 501
sss 501 333
qqq 501 121
bankcode are bracnhes whose parent are pbankparentcode .
-1 in pbamkparentcode indicates that it is parent bank.
i want an output something like this
pbankname (branch) pbanmcode(branch) pbankcode(parent) pbankname(parent)
Regards

Hi
well i am attaching the results in text format.because the forum is screwing up the formatting..:-)

for any levels of a hierarchy (more then 1) method of solve this task has to be another:
Code:create or replace type txt_nodes as table of varchar2(1000);
/
SQL> select lpad('.',(level-1)*2,'.') || '[' || to_char(a.node_id) || '-->' || a.txt ||']' node,
cast(multiset(select '[' || to_char(c.node_id) || '-->' || c.txt ||']'
from test_tree c
where a.node_id <> c.node_id
connect by prior c.root_id=c.node_id
start with c.node_id=a.node_id ) as txt_nodes) r
from test_tree a
connect by prior a.node_id=a.root_id
start with a.root_id=0;
