Superset 一次支持 query/join 个表吗?

Does Superset support query/join multiple tables at a time?

超集documentation中说不可能query/join多表

Can I query/join multiple tables at one time?
Not directly no. A Superset SQLAlchemy datasource can only be a single table or a view.

但根据我的经验,我可以毫无问题地做到这一点。是过时的文档,还是我还不明白的东西?

是的,超集sql实验室支持一次连接多个表。

select * from charles.m_jdbc_3 m left join druid.druid_supervisors d on m.id=d.id
where m.id={{id_value}} and m.value={{value_key}}

无法简单地进行连接..
