Nope...

  1 SELECT *
  2 FROM (SELECT * FROM treenode ORDER BY parentid, nodeorder)   3 START WITH parentid=0
  4* CONNECT BY PRIOR ID = parentid
SQL> /
  FROM (SELECT * FROM treenode ORDER BY parentid, nodeorder)

                      *

ERROR at line 2:
ORA-01472: cannot use CONNECT BY on view with DISTINCT, GROUP BY, etc.
