我如何在 pl/sql 查询函数中设置循环，每个循环的结果都放在不同的列中并全部放在一个表中。

功能是：

select t1.aaa, coalesce(t2.bbb_count, 0) bbb_count,
    coalesce(t2.ccc_sum, 0) ccc_sum
from (
  select distinct aaa
  from nrb
) t1
left join (
  select t.aaa, count (t.bbb) bbb_count, sum (t.ccc) ccc_sum
  from nrb t
  where t.vvv IN  ('3','4','5','6','D','E','F')
    and t.ddd like '50%'
    and t.eee >= TO_DATE('2012/03/21','YYYY/MM/DD')
    and t.eee <= TO_DATE('2012/07/21','YYYY/MM/DD')
  group by t.aaa
) t2 on t1.aaa = t2.aaa
order by t1.aaa;

这个函数会给我一个有 200 行和 3 列的表。我需要做一个循环

"和 t.ddd 像 '50%'"

line ，从 50 到 55。我的意思是结果将是 200 行和 15 列。
