创建TEST表：
Create table test as select * from user_objects;
创建TEST_BAK表：
Create table test_bak as select * from test;
创建procedure：
Create or replace procedure pro_test
is
id_cnt number;
begin
select count(object_id) into id_cnt from test;
dbms_output.put_line('Object_id:'||id_cnt);
end;
 创建trigger：
 
CREATE OR REPLACE TRIGGER "TEST"."TRG_TEST"                                  
after insert or delete on TEST for each row                                                                  
begin                                                                         
dbms_output.put_line('modified!');                                            
exception                                                                     
when others then                                                              
dbms_output.put_line(sqlerrm);                                                
end;                    
/
 
创建index：
Create index idx_test_object_id on test(object_id);
 
创建约束：
主键：
alter table test_bak add constraint pk_test_bak primary key (object_id);
外键：
alter table test add constraint fk_test foreign key (object_id) references test_bak(object_id);

Flashback drop并没有把FK恢复！
 
总结：
在recyclebin on的状态下，Drop table之后，会将table,trigger和index重新命名，table,trigger状态无效，index状态有效，procedures则不会重命名，但是状态无效，flashback drop可以恢复表以及相关object，但是对于procedures，trigger和index需要自己手动rename和compile，FK不能被恢复，需要手动创建。
