Ugh is right, I have to live with the structure!
Perhaps I can explain this better.
I have table EMP with a list of emplyees, and table SUB with each employees subordinates. What I
need is a list of all the subordinates for a given EMP rolled up to include all subordinate
emplyees. So if I select employee SMITH I get:
SMITH
ADAMS
JONES
ARMSTRONG
FRANK
JAMES
BROWN
But The structure is still the same as described before.
CREATE TABLE EMP (row_id number, ename varchar2(30));
CREATE TABLE SUB (row_id_parent number, ename varchar2(30));
Just assume the names are unique for this test case.
INSERT INTO EMP (1,'SMITH');
INSERT INTO EMP (2,'ADAMS');
INSERT INTO EMP (3,'JONES');
INSERT INTO EMP (4,'ARMSTRONG');
INSERT INTO EMP (5,'FRANK');
INSERT INTO EMP (6,'JAMES');
INSERT INTO EMP (7,'BROWN');
INSERT INTO SUB (1,'ADAMS');
INSERT INTO SUB (1,'BROWN');
INSERT INTO SUB (2,'JONES');
INSERT INTO SUB (2,'ARMSTONG');
INSERT INTO SUB (2,'JAMES');
INSERT INTO SUB (4,'FRANK');
Hope this helps with your head ache:)

I figure "smith" can be "implied", you could union him in, but you already sort of know "smith"
