正規清理回收站的表：
1、使用 PURGE TABLE original_table_name; 這裡的 original_table_name 表示未 drop 以 前的名稱
2、使用 PURGE TABLE recyclebin_object_name; 這裡的 recyclebin_object_name 表示回 收站中的物件名稱
3、使用 PURGE TABLESPACE tablespace_name 從指定的表空間中清除所有的丟棄物件
4、使用 PURGE TABLESPACE tablespace_name USER user_name 從回收站中清除屬 於某個特定使用者的所有丟棄物件。
5、DROP USER user_name cascade 直接刪除指定使用者及其所屬的全部物件，也就是說， DROP USER 命令會繞過回收站進行直接刪除。
6、使用 PURGE RECYCLEBIN 命令清除使用者自己的回收站
7、PURGE DBA_RECYCLEBIN 從所有使用者的回收站清除所有物件


假如發生了這個場景，應該怎麼去解決？
