Merging two SQLs

Question

Hi Gurus,
I have two SQLs which are;
select bbe
from alu_sdhnm.dwdm_logical_stats dis_1
where bbe <= (select max(bbe) from alu_sdhnm.dwdm_logical_stats ic_1 where ic_1.datetime=dis_1.datetime)
order by bbe desc;
select es
from alu_sdhnm.dwdm_logical_stats dis_2
where es <= (select max(es) from alu_sdhnm.dwdm_logical_stats ic_2 where ic_2.datetime=dis_2.datetime)
order by es desc;
Those are showing top es and bbe values inside dwdm_logical_stats table seperately by using correlated sub-query. My question is, how can i see them inside one single query? In addition, in the same row if bbe has the highest value, es has not the highest.
Thank you,
Ogan

I'm forgetting the little detail of the data ;)
What do each of these give you?
  SELECT
      bbe,
      DENSE_RANK() OVER (ORDER BY BBE DESC) bbe_rank,
      ROW_NUMBER() OVER (ORDER BY BBE DESC) row_num
    FROM alu_sdhnm.dwdm_logical_stats;And:
    SELECT
      es,
      DENSE_RANK() OVER (ORDER BY ES DESC) es_rank,
      ROW_NUMBER() OVER (ORDER BY ES DESC) row_num
    FROM alu_sdhnm.dwdm_logical_stats)And finally:
SELECT bbe,  bbe_rank, es, es_rank
  FROM (
  SELECT
      bbe,
      DENSE_RANK() OVER (ORDER BY BBE DESC) bbe_rank,
      ROW_NUMBER() OVER (ORDER BY BBE DESC) row_num
    FROM alu_sdhnm.dwdm_logical_stats) ilv1
JOIN (
    SELECT
      es,
      DENSE_RANK() OVER (ORDER BY ES DESC) es_rank,
      ROW_NUMBER() OVER (ORDER BY ES DESC) row_num
    FROM alu_sdhnm.dwdm_logical_stats) ilv2
ON (ilv1.row_num = ilv2.row_num)
