使用join语句在google big query中显示表别名的所有字段

Question

我有一个简单的连接语句的查询，我想打印一个表的所有字段。

select t1.id, t1.field1, ..., t1.fieldN
from first_table as t1
join second_table as t2 on t1.id = t2.id
where t1.field1 = "some value"

我可以用某种方式构建（或存在一个快捷方式）带有*通配符的select语句吗？

select t1.*
from first_table as t1
join second_table as t2 on t1.id = t2.id
where t1.field1 = "some value"

Answer 1

当您使用BigQuery Legacy SQL加入时，如第二个查询中的帖子 - 您将输出前缀为表别名的输出字段为t1_id，t1_field1等等

请使用没有此行为的BigQuery Standard SQL

  

试试

#standardSQL
SELECT t1.*
FROM first_table AS t1
JOIN second_table AS t2 ON t1.id = t2.id
WHERE t1.field1 = "some value"
