如何将查询定义为常量并对表进行左连接?
我试图这样做,但它没有工作
#standardSQL
select
"name" custom_campaign_defined,
"welcome" as funnel_step
from '1' data
left join table on table.campaign = data.custom_campaign_defined
如何解决这个问题?

只需使用子查询。它是这样的,虽然引用的列不清楚你到底想要什么:
select t."name" as custom_campaign_defined,
t."welcome" as funnel_step
from (select '1' as custom_campaign_defined) d left join
table t
on t.campaign = d.custom_campaign_defined
