I noticed a lot of people were having issues with 9. ARPU2. Even when I click "give me the code" after a bunch of failed tries, I was still told my code was wrong. I wanted to provide the answers that worked for me.
PART 1:
with daily_revenue as (
select
date(created_at) as dt,
round(sum(price), 2) as rev
from purchases
where refunded_at is null
group by 1
),
daily_players as (
select
date(created_at) as dt,
count(distinct user_id) as players
from gameplays
group by 1
)
select * from daily_players order by dt;PART 2: Just copy and paste this over the entire code to prevent any confusion.
with daily_revenue as (
select
date(created_at) as dt,
round(sum(price), 2) as rev
from purchases
where refunded_at is null
group by 1
),
daily_players as (
select
date(created_at) as dt,
count(distinct user_id) as players
from gameplays
group by 1
)
select
daily_revenue.dt,
daily_revenue.rev / daily_players.players
from daily_revenue
join daily_players using (dt);
