Question

如何在 BigQuery 中用简单的单行定义临时常量表(或 Postgres，其语法可能适用于 BigQuery)？

with my_fruits as (
--- ??? define a table 
--- consisting of a single column fruit_name
--- with values ('apple', 'pear', 'gooseberry', ...  (12 more fruits))
)
select * from my_fruits left join 
(select fruit_name, 1 is_present from my_dataset.your_fruits)
using (fruit_name)

Answer 1

您可以使用UNNEST :

select * from unnest(['apple', 'pear', 'gooseberry']) as fruit_name

您还可以加入 UNNEST directly .
