Google bigquery 如何在Bigquery中查询多个Firebase项目？

如何放置选择查询以从多个Firebase项目提取数据

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

如何在单个查询中查询abc项目和xyz项目。目前，我正在使用两个查询从Project abc&xyz及其数据集表中提取数据

查询abc项目

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

查询xyz项目

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

来自两个Firebase项目的单个查询的预期结果

请。注: com.abc数据是从project abc数据集表格中提取的 com.xyz数据是从项目xyz数据集表中提取的

id版本事件\日期会话唯一用户

com.abc 6.6 01-Sep-19 45745 17098

com.xyz 6.7 01-Sep-19 42372 12087
