13.3 day retention

wat is wrong with the code?

I don’t know what to type

date(g1.created_at) as dt,
round(100 * count(distinct (g2.user_id))) /
count(distinct (g1.user_id)) as retention
from gameplays as g1
left join gameplays as g2 on
g1.user_id = g2.user_id
and date(g1.created_at) = date(datetime(g2.created_at, ‘-1 day’))
group by 1
order by 1
limit 100;
