9.You ran this command on a source database:
$> expdp hr/hr DIRECTORY=dumpdir DUMPFILE=empl.dmp VIEWS_AS_TABLES=emp_dept
On the target database, you run this command:
impdp hr/hr DIRECTORY=dumpdir DUMPFILE=empl.dmp VIEWS_AS_TABLES=emp_dept
Which two statements are true?
A) The expdp operation exports the table definitions for tables that are queried in the emp dept view.
B) The impdp operation creates emp_dept as a view.
C) The expdp operation exports all rows that are displayed when querying the emp_dept view with no filter.
D) The expdp operation exports all rows for tables contained in the defining query of the emp_dept view.
E) The impdp operation creates separate tables for each table contained in the defining query of the EMP_DEPT View.
F) The impdp operation creates emp_dept as a table.
Answer:CE
(解析:實驗證明 VIEWS_AS_TABLES 導出時會導出視圖中查詢到的數據,導入時會把 emp_dept 當作表創建。C 答案的意思是:expdp 操作將導出查詢 EMP_DEPT 視圖時顯示的所有行,而不使用過濾器,所以正確。D 答案的意思是:expdp 操作將導出 EMP_DEPT 視圖定義中包含的表的所有行,導出的是表的所有行,所以不對。E 答案是將為 emp_dept 視圖中涉及到的表單獨創建各自的表,其實是就建立一個表 emp_dept。本題的難度在于對答案的英文理解。)
