从结果集SQL select隐藏列

我想从显示结果的第二次选择中隐藏

EMPNO

结果，因为我已经在第一次选择中有了它，有什么想法吗

   select *from
(select M.EMPLOYEE_NUMBER,count(M.EMPLOYEE_NUMBER)as empnumcon,sum(C.MEMBER_PAID_AMOUNT)
from CPMS.ABDULLAH_MEMBERS M,CPMS.ABDULLAH_EMPLOYMENTS E,CPMS.ABDULLAH_SALARIES S,CPMS.ABDULLAH_CONTRIBUTIONS C
where M.MERGE_ID=E.MERGE_ID
and E.EMPLOYMENT_ID=S.EMPLOYMENT_ID
and S.SALARY_ID=C.SALARY_ID
group by M.EMPLOYEE_NUMBER)t1
inner join
(select EMPNO,count(EMPNO)as numfacon,sum(PENSND)
from CON1.PEN_DED
where PENSND !=0
group by EMPNO)t2
on t1.EMPLOYEE_NUMBER = t2.EMPNO

我认为，尽管使用*键，你还是应该选择你的列，因为一旦你选择了任何一列，它就会出现在结果中

select t1.EMPLOYEE_NUMBER,
empnumcon
from
(select M.EMPLOYEE_NUMBER,count(M.EMPLOYEE_NUMBER)as empnumcon,sum(C.MEMBER_PAID_AMOUNT)
  from CPMS.ABDULLAH_MEMBERS M,CPMS.ABDULLAH_EMPLOYMENTS E,CPMS.ABDULLAH_SALARIES S,CPMS.ABDULLAH_CONTRIBUTIONS C
          where M.MERGE_ID=E.MERGE_ID
          and E.EMPLOYMENT_ID=S.EMPLOYMENT_ID
         and S.SALARY_ID=C.SALARY_ID
         group by M.EMPLOYEE_NUMBER)t1
          inner join
          (select EMPNO,count(EMPNO)as numfacon,sum(PENSND)
           from CON1.PEN_DED
          where PENSND !=0
          group by EMPNO)t2
         on t1.EMPLOYEE_NUMBER = t2.EMPNO

不要从第二个SO中选择“EMPNO”。我不能，因为我在末尾使用它。您不需要选择“EMPNO”来在结尾条件中使用它。
