WITH in BigQuery

Question

BigQuery 是否支持 WITH 子句？我不喜欢格式化太多子查询。

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

最近推出的 BigQuery Standard SQL 确实支持 WITH 子句

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
