來自常量的bigquery左連接

Question

如何將查詢定義爲常量並對錶進行左連接？

我試圖做這樣的，但它不是workitng

#standardSQL 
select 
"name" custom_campaign_defined, 
"welcome" as funnel_step 
from '1' data 
left join table on table.campaign = data.custom_campaign_defined 

如何解決這一問題？

Answer 1

只需使用子查詢。這是類似的東西，雖然參考欄目不清楚你確切想要什麼：

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
