How to put Select query to pull data from Multiple Firebase Projects
How to query abc project & xyz project in a single query. At present i am putting two queries to extract data from Project abc & xyz & its dataset tables.
Querying abc Project
SELECT app_info.id,event_date,app_info.version,
count(*) as sessions,
count( distinct user_pseudo_id ) as uniqueusers
FROM `abc-1075.analytics_151541058.events_*`
where event_name='session_start' and
_TABLE_SUFFIX BETWEEN '20190901' AND '20190931' group by 1,2,3
Querying xyz Project
SELECT app_info.id,event_date,app_info.version,
count(*) as sessions,
count( distinct user_pseudo_id ) as uniqueusers
FROM `xyz-1056.analytics_151414092.events_*`
where event_name='session_start' and
_TABLE_SUFFIX BETWEEN '20190901' AND '20190931' group by 1,2,3
