集團按序號是不是默認啓用。您必須將_sql_compatibility設置爲1

select deptno, sum(sal) 
    from emp 
    group by 1 
    order by 1 
SQL>/
select deptno, sum(sal) 
     * 
ERROR at line 1: 
ORA-00979: not a GROUP BY expression 

alter session set "_sql_compatibility"=1 

Session altered. 

select deptno, sum(sal) 
from emp 
group by 1 
order by 1 

SQL>/

    DEPTNO SUM(SAL) 
---------- ---------- 
     10  8750 
     20  10875 
     30  9400
