Answer 1

您創建的目錄爲xmldir3，這是一個帶引號的標識符因此這將是大寫的數據字典。但是，你可以用小寫來表示它。您需要使用：

bfilename('XMLDIR3', 'book.xml') 

您可以通過查詢all_directories視圖檢查實際的目錄名稱：

SQL> CREATE OR REPLACE DIRECTORY xmldir3 AS '/opt/user/nishanth/xmldir'; 

Directory created. 

SQL> SELECT directory_name, directory_path FROM all_directories; 

DIRECTORY_NAME     DIRECTORY_PATH 
------------------------------ ---------------------------------------- 
XMLDIR3      /opt/user/nishanth/xmldir
