Recursive SQL - Parent Child

Question

Hi,
In a table I got hierarchial data (parent child), where parent is child to some other parent.
This is upto level4.(I mean Child=>Parent1=>Parent2=>Grand Parent)
Child=>Parent
A1=>B1
A2=>B1
A3=>B1
B1=>B2
B2=>B3
B3=>B4
I need result like - Each child will have its all parents and subsequent parent
Like :
Child Parent1 Parent2 Grand Parent
=========================
A1=>B1 -- First Parent of A1
A1=>B2 -- Second Parent of A1
A1=>B3 -- Third Parent of A1
A1=>B4 -- Grand Parent
Please help. Is this possible with connect by feature? I tired using it but i am getting only parents for each.
Thanks
Bhushan

Hi, Bhusan,
To repeat some value from the first row on all of the rows connected to it, use CONNECT_BY_ROOT
SELECT     CONNECT_BY_ROOT child   AS starting_point
,     parent
FROM     table_x
START WITH     child     = 'A1'     -- or whatever
CONNECT BY     chilD     = PRIOR parent;
