Answer 1

嗯。 . .这似乎符合您的描述：

select date_trunc('month', day), category,
       sum(transaction_amount), count(distinct user_id)
from (select d.*,
             min(category) over (partition by userid, date_trunc('month', day)) as min_category,
             max(category) over (partition by userid, date_trunc('month', day)) as max_category
      from daily d
     ) d
where min_category <> max_category -- at least two categories
group by date_trunc('month', day), category;
