union select 2 from dual
union select 3 from dual
union select 4 from dual
union select 5 from dual
union select 6 from dual)
select   ltrim(max(sys_connect_by_path(to_char(col1),',')),',') col1
from (select col1,
       row_number() over(order by col1) r1,
       row_number() over(order by col1)-1 r2

start with r1 = 1
connect by prior r1=r2;
