oracle DELETE records while MERGE

Question

I MERGE records from newtest to test .

merge into test t
using newtest nt
on (t.id = nt.id)
when matched then
  update
     set t.name = nt.name
when not matched then
  insert (id, name)values (nt.id, nt.name); 

Those records in newtest which are fit for on conditions need be deleted.

Though i could do it with a delete SQL, but i want to know can it be done in that MERGE sentence?

As kordiko clarified, you cannot delete from another table using the MERGE statement. You can accomplish the delete in a separate statement as below:

DELETE FROM newtest nt
WHERE NOT EXISTS
(SELECT 1 FROM test t where t.id = nt.id);
