ORA-00903: invalid table name

Hi, I tried to delete a record from a table and got the message ORA-00903: invalid table name

I can describe the table.

I can select from the same table.

With select, I can see the record I want to delete.

I tried deleting with owner.table-name, same result.

I can see the table records in EM, the record I want to delete is there.

I just can't delete it.

SQL> select count(*) from stable;

  COUNT(*)

----------

     15367

SQL> delete * from owner.stable where S_ID = 1234567;

       *

ERROR at line 1:

ORA-00903: invalid table name

Any ideas?

Thanks!
