在特定专栏中，我想处理管道函数并同时使用 concat 函数。我怎样才能做到这一点？下面查询

In a particular column, I want to handle pipe function as well as make use of a concat function at the same time. How can I achieve this? Query below 

select regexp_replace(id,'["\t\n|]', '') as CONCAT('SF_',id) as id
      ,lastmodifiedbyid
      ,lastmodifieddate
from Enterprise_raw

您可以将一个函数包装到另一个函数中：

 select concat('SF_',regexp_replace(id,'["\t\n|]', '')) as id,
       ,lastmodifiedbyid
       ,lastmodifieddate
  from Enterprise_raw
