Sql 在联接表达式中使用列而不在group by语句中使用列

在上面的查询中，我在语句

c.id=d.id

select c.id, c.fname, c.lname, d.phoneList
  from customers c
  left outer join
       (
        select listagg(telNo, ',') within group (order by telNo) as phoneList
          from customerPhones 
         group by p.telNo
       ) d 
   on (c.id = d.id)

仅当我将其包含在select语句中，并且表示需要将其包含在group by语句中时，它才起作用。是否有任何方法可以使用d.id而不必将其包含在group by语句中？

只需简化为这个

ORA-00904 "d.id" invalid identifier.

但是您只在d中选择电话号码，怎么可能有d.id？

id

列必须出现在外部连接的选择列表中query@ziggy对不起，现在我明白了，外接…：D
