正规清理回收站的表：
1、使用 PURGE TABLE original_table_name; 这里的 original_table_name 表示未 drop 以前的名称
2、使用 PURGE TABLE recyclebin_object_name; 这里的 recyclebin_object_name 表示回收站中的对象名称
3、使用 PURGE TABLESPACE tablespace_name 从指定的表空间中清除所有的丢弃对象
4、使用 PURGE TABLESPACE tablespace_name USER user_name 从回收站中清除属于某个特定用户的所有丢弃对象。
5、DROP USER user_name cascade 直接删除指定用户及其所属的全部对象，也就是说， DROP USER 命令会绕过回收站进行直接删除。
6、使用 PURGE RECYCLEBIN 命令清除用户自己的回收站
7、PURGE DBA_RECYCLEBIN 从所有用户的回收站清除所有对象

假如发生了这个场景，应该怎么去解决？
