wm_concat and order

719215Nov 3 2009 — edited Nov 4 2009
When ran the following query, I got the enames with unordered result . Does anyone know how to get the wm_concat column to order\sort ? I use oracle v10 . Any thoughts are appreciated.Thanks.

select distinct deptno ,wm_concat(ename) over ( partition by deptno order by deptno ) as enames
from emp
group by deptno,ename
order by deptno

current output: 
DEPTNO ENAMES 
10	MILLER,CLARK,KING 
20 	SCOTT,JONES,FORD,ADAMS,SMITH 
30	MARTIN,JAMES,WARD,ALLEN,TURNER,BLAKE
Target output: 
DEPTNO ENAMES 
10	CLARK,KING,MILLER 
20 	ADAMS,FORD,JONES,SCOTT,SMITH 
30	ALLEN,BLAKE,JAMES,MARTIN,TURNER,WARD
