Example..
SQL> ed
Wrote file afiedt.buf
  1  select deptno, ltrim(sys_connect_by_path(ename,','),',') as enames
  2  from (
  3        select deptno, ename, row_number() over (partition by deptno order by ename) rn from emp
  4       )
  5  where connect_by_isleaf = 1
  6  connect by deptno = prior deptno
  7         and rn = prior rn + 1
  8  start with rn = 1
  9* order by deptno
SQL> /
    DEPTNO ENAMES
        10 CLARK,KING,MILLER
        20 ADAMS,FORD,JONES,SCOTT,SMITH
        30 ALLEN,BLAKE,JAMES,MARTIN,TURNER,WARD
