i want to aggregate postgres data, but i need where one query where i can use aggregate function for different datatype . Basically want to combine this two queries.
select browser_id, jsonb_object_agg(key, val)
from (
select browser_id, key, sum(value::numeric) val
from aggregated_browser_days, jsonb_each_text(geo_city)
group by browser_id, key
) s
group by browser_id;
select browser_id, sum(pageviews) as total_pageviews,
STRING_AGG(DISTINCT browser_family, ',') AS browser,
STRING_AGG(DISTINCT device_model, ',') AS device_model,
SUM(timespent) as total_timespent, SUM(sessions) as session_count
from data
GROUP BY browser_id
Can anyone please guide me?? Thanks in advance
This data is coming from two different tables. So a JOIN
seems like the right approach. Just in case the base tables contain different sets of browsers, I am suggesting a FULL JOIN
:
select *
from (select browser_id, jsonb_object_agg(key, val)
from (select browser_id, key, sum(value::numeric) as val
from aggregated_browser_days cross join lateral
jsonb_each_text(geo_city)
group by browser_id, key
) s
group by browser_id
) bd full join
(select browser_id, sum(pageviews) as total_pageviews,
STRING_AGG(DISTINCT browser_family, ',') AS browser,
STRING_AGG(DISTINCT device_model, ',') AS device_model,
SUM(timespent) as total_timespent, SUM(sessions) as session_count
from data
group by browser_id
) b
using (browser_id)
