在BigQuery中使用

Question

BigQuery是否支持该WITH条款？我不喜欢格式化太多的子查询.

例如:

WITH alias_1 AS (SELECT foo1 c FROM bar)
, alias_2 AS (SELECT foo2 c FROM bar a, alias_1 b WHERE b.c = a.c)
SELECT * FROM alias_2 a;

Answer 1

最近介绍的BigQuery Standard SQL确实支持WITH子句
了解有关WITH子句的更多信息

另请参阅如何启用标准SQL

Answer 2

Bigqery Standard SQl支持WITH子句。语法如下所示

with table2 as (Select column1,column2 from table1)
    select column1 from table2
