Oracle 9i restore the deleted table with RMAN

In actual work, developers often accidentally delete an important table. At this time, they will find the Administrator to retrieve the deleted table. The specific scenarios are as follows:
1. Developers:
SQL> conn usr1/usr1
Connected.
SQL> create table t (id int, name varchar2 (10 ));
Table created.
SQL> insert into t values (0, yejun0 );
1 row created.
SQL> insert into t values (1, yejun1 );
1 row created.
SQL> commit;
Commit complete.
SQL>
