表不存在了，但还能select count(1)，除此外其他操作都失败，求各路大神解释！！！

发这个帖子主要是有两个疑问：
第一：表已经干掉了为什么还能select count(1),但又做不了其他操作，导致该表名无法再次使用；
第二：网上的帖子都是count(1)和count(*)一样，但是在此似乎不一样，何解？
我被这问题整的很是蛋疼，又是生产环境，又不能随便动，很无助啊！！！！

如下是整个故事发生的由来及异常：
--导致下述异常的可能性操作：
第一步：(删除临时表报如下错)
DROP TABLE B_CIF_ENT_BASIC_EX;
ORA-38301: can not perform DDL/DML over objects in Recycle Bin
第二步：(清空回收站)
purge recyclebin;
再往后就报了下列异常。。。。
