Joining two queries with different where clauses into 1 table

This is probably a pretty simple question, but I have two separate queries that I would like to join into one table. One of the queries shows sign ups to my website by month and the other query shows sign ups that have made a purchase. I would like to combine the two queries into one table so I have the following table:

Month      Sign-ups  Sign-ups with Purchase
Jan 2019   250       40
Feb 2019   500       120

How can I do that? Here’s my two queries:

Sign ups:

select
  count(u.id) as Sign_Ups
  , month(From_iso8601_timestamp(u.created)) as Month
from
   prodjoinreel.users u
where
  year(From_iso8601_timestamp(u.created)) = 2019
group by
  2
order by
  2 asc

Sign ups with purchase:

select
  count(distinct g.owner) as Sign_Ups_with_Reel
  , month(From_iso8601_timestamp(u.created)) as Month
from
  prodjoinreel.goals g
  right join prodjoinreel.users u on
    g.owner = u.id
where
  year(From_iso8601_timestamp(u.created)) = 2019
group by
  2
order by
  2 asc

thank you!

Answer

I think that you can just add a count(distinct u.id) to the second query:

select
  month(From_iso8601_timestamp(u.created)) as Month,
  count(distinct u.id) as Sign_Ups,
  count(distinct g.owner) as Sign_Ups_with_Reel
from
  prodjoinreel.users u
  left join prodjoinreel.goals g on g.owner = u.id
where year(From_iso8601_timestamp(u.created)) = 2019
group by 1
order by 1

Note: I changed your right join to a left join; most people tend to consider that right joins are rather counter-intuitive, and favor left joins instead.
