i have this query:
select IF(user_name IS NULL or user_name= '', distinct_id, user_name )
as user_info, event, count(event) as event_count
from mixpanel
where
(mixpanel.event = 'app_open' or
mixpanel.event = 'post_created' or
mixpanel.event = 'create_comment' or
mixpanel.event = 'class_opened' or
mixpanel.event = 'post_read')
AND
class_id = 'AKSJSDKSD'
group by event, user_name, distinct_id
order by user_name desc
and it gives me the following results:
+-----------+------------+--------+
| user_info | event | event_count |
+-----------+------------+--------+
| Ben Cho | up | 12 |
| Lee Mar | up | 21 |
| Lee Mar | side | 12 |
| Lee Mar | down | 16 |
| Al Gov | up | 14 |
| Al Gov | down | 13 |
| Al Gov | side | 13 |
+-----------+------------+--------+
what i need is to aggregate each user data like so:
+-----------+------------+--------+
| user_info | up | down | side
+-----------+------------+--------+
| Ben Cho | 12 | 0 | 0 |
| Lee Mar | 21 | 16 | 12 |
| Al Gov | 14 | 13 | 13 |
+-----------+------------+--------+
how can i achieve this on mySql?
thank you!
From what I can tell, you just want conditional aggregation. There is no need for group_concat()
:
select (case when user_name IS NULL or user_name = '' then distinct_id else user_name
end) as user_info,
sum(mp.event = ('app_open')) as num_app_open,
sum(mp.event = ('post_created')) as num_post_created,
sum(mp.event = ('create_comment')) as num_create_comment
from mixpanel mp
where mp.event in ('app_open', 'post_created', 'create_comment') and
class_id = '-KtmM9EACwDTR98a_yU9'
group by user_info
order by user_info desc;
