知识点
- 和上一题一样加上一行计数的列统计筛选条件后进行计数
- 最后表格筛选条件就是计数大于等于的行
代码
select g.id, g.user_id, g.product_name, g.status, g.client_id, g.date
from (
select *, count(*) over(partition by user_id) as c
from order_info
where date > '2025-10-15'
and status = 'completed'
and product_name in ('C++', 'Java', 'Python')
) as g
where g.c >= 2
order by g.id
