Error in Merge (Upsert)

Question

I was just trying to see how merge worked but got error while running the following script.
Could you tell what is missing in the statement?
merge into emp_new emp_new
using(select
EMPNO ,
ENAME ,
JOB ,
MGR ,
HIREDATE ,
SAL ,
COMM ,
DEPTNO
from emp) emp
on (emp_new.empno=emp.empno)
when not matched then
insert (emp_new.EMPNO ,
emp_new.ENAME ,
emp_new.JOB ,
emp_new.MGR ,
emp_new.HIREDATE ,
emp_new.SAL ,
emp_new.COMM ,
emp_new.DEPTNO )
values
(emp.EMPNO ,
emp.ENAME ,
emp.JOB ,
emp.MGR ,
emp.HIREDATE ,
emp.SAL ,
emp.COMM ,
emp.DEPTNO )
Thanks
