Question

The MySQL table is simple:

id | name | create_time

Every time the user makes an operation, it inserts one record into this table, like

1 | "do ABC" | 2011-12-05

2 | "do BCD" | 2011-12-05

I want to get the top 50 operations from this table during the last 7 days. How can I write the SQL?

Answer 1

select count(id), name
from tablename
where DATE_SUB(NOW(), INTERVAL 7 DAY) < create_time 
group by name
order by count(id) desc
limit 50;
