使用python进行多表关联查询，可以参考：https://community.memfiredb.com/topic/311/使用python接口来进行关联查询操作
使用JS进行多表关联查询，可以参考：

例如：Query foreign tables

countries (id int8 primary key, name text);
create table
cities (
id int8 primary key,
country_id int8 not null references countries,
name text
);
查询
const { data, error } = await supabase
.from('countries')
.select(`
name,
cities (
name
)
`)
返回结果
