你show recyclebin;看看回收站中是否有删除的表，然后进行闪回删除

flashback table emp1 to before drop;

或者通过回收站中的名字执行闪回：

flashback table “BIN$opkhRg3T0MPgVaUgq/kbkw==$0” to before drop;

可以，我刚测了下：

SQL> create user testA identified by testA;

User created.

SQL> create user testB identified by testB;

User created.


SQL> grant unlimited tablespace to testA;

Grant succeeded.

SQL> grant unlimited tablespace to testB;

Grant succeeded.

SQL> conn / as sysdba
Connected.
SQL> grant create session to testA;

Grant succeeded.

SQL> grant create session to testB;

SQL> conn testA/testA
Connected.
SQL> show recyclebin;



SQL> conn / as sysdba

SQL> grant resource,public to testA;

Grant succeeded.

SQL> grant resource,public to testB;

Grant succeeded.

SQL> conn testA/testA
Connected.
SQL> create table a(id int);

Table created.

SQL> insert into a values(1);

SQL> insert into a values(2);
