Sql 按子查询内部分组

我在Databricks内部使用SQL。下面的查询是有效的，但我还想按一个名为sale_id的列进行分组。我该如何进行

%sql
select
  (select
     count(distinct time)
  from
    table
  where
    sign_up > 0)
  /
  (select
     count(distinct time)
   from
     table
   where
    action > 0 or
    click > 0)
    as cc3

使用条件聚合写入查询：

select (count(distinct case when sign_up > 0 then time end) /
        count(distinct case when action > 0 or click > 0 then time end)
       ) as cc3
from table;

然后，通过分组很容易：

select col,
       (count(distinct case when sign_up > 0 then time end) /
        count(distinct case when action > 0 or click > 0 then time end)
       ) as cc3
from table
group by col;

工作得很有魅力。非常感谢。
