How can I order a hierarchical query on Oralce 8i. I know that I can do this on Oracle 9i like this :

select
empno, lpad(' ',2*level) || ename as Ename
from
emp
start with
mgr is null
connect by prior
empno = mgr
order siblings by
Ename

and query returns :

EMPNO ENAME
---------- --------------------
7839 KING
7698 BLAKE
7499 ALLEN
7900 JAMES
7654 MARTIN
7844 TURNER
7521 WARD
7782 CLARK
7934 MILLER
7566 JONES
7902 FORD
7369 SMITH
7788 SCOTT
7876 ADAMS

But on Oracle 8i I get :
ORA-00924: missing BY keyword

OK, ORDER SIBLINGS BY is not supported on Oracle8i, but I to order hierarchial query on Oracle 8i.

Thank you in advance
