如何在presto sql中获取最近3个月的记录

Question

I would like to find the frequency of logins of user A within the last 3 months but somehow my date filter in the WHERE clause has some errors.. not sure whether the below is a correct way to retrieve latest 3 months records for presto sql.

select userid, count(*)
from user_login
where userid = 3321 and date(from_unixtime(cast(date_login as int)) >= date_add('day',-90,current_date))
group by 1 

Answer 1

Wouldn't this work?

where date_login > cast(date_add(day, -90, current_date) as timestamp)

or:

where date_login > cast(current_date - interval '90' day as timestamp)
