PLSQL CSV文件讀取和寫入

OWNER SYS 
DIRECTORY_NAME ME 
DIRECTORY_PATH \\172.16.20.11\Mad\ 


begin 

vSFile := utl_file.fopen('ME','20170405.csv','R'); 
IF utl_file.is_open(vSFile) THEN 
LOOP

我得到錯誤：PLSQL CSV文件讀取和寫入

這是什麼問題？你是否完成了錯誤信息所說的內容？ – Aleksej

Oracle是否真的允許（識別）爲[服務器文件系統上的目錄]在Windows的網絡路徑（http://docs.oracle.com/database/121/CNCPT/glossary.htm#CNCPT44466）？你可以將該路徑映射到一個驅動器盤符並查看它是否有效？（也可能是與操作系統權限或Oracle授權的，當然問題...） –

之所以獲得這樣的問題是，你沒有read或write許可權directory。

運行下面的查詢，看看是否有read和write權限的：

SELECT * 
     FROM all_tab_privs 
    WHERE table_name = 'your_directory name';

如果發現不具有任何訪問然後授予讀寫PRIVS。

SQL>CREATE OR REPLACE DIRECTORY dir1 as '/opt/oracle/'; 

SQL>GRANT READ,WRITE on dir1 to <Required user>; (if you want to give access to particular user) 
OR 
SQL>GRANT READ,WRITE on dir1 to PUBLIC; (if you want to give access to all users then give access to public)

我已閱讀並寫permision – kumarh

@kumarh。如果你有權限，那麼在任何情況下你都必須得到這個問題。在這裏看到我的帖子與演示：http://stackoverflow.com/questions/42720366/plsql-open-file-in-write-mode/42720486#42720486 – XING

你的錯誤告訴你到底是什麼問題：

*Cause: An attempt was made to read from a file or directory that does not exist, or file or directory access was denied by the operating system.

，做些什麼來解決它：

*Action: Verify file and directory access privileges on the file system, and if reading, verify that the file exists.

所以你指定：

DIRECTORY_PATH \\172.16.20.11\Mad\

您是否能夠實際訪問\\172.16.20.11\Mad\與Oracle的用戶？

如果沒有，那麼你需要grant read, write on directory to user並檢查操作系統權限的用戶到該路徑。

還要考慮做一個網絡共享驅動器號，而不是UNC路徑。

我能夠訪問此路徑，我有權限讀寫 – kumarh

作爲哪個用戶你可以訪問它？ –

我不知道確切的規則是什麼甲骨文可以或不可以作爲目錄打開，但在Windows中有一個名爲驅動器和URL之間的差異，即使Windows資源管理器可以呈現兩個相同的方式。例如，我可以'dir'\\ ln-sharepoint.blahblah.net \ Root \ whatever \ docs「'或者在資源管理器中瀏覽它，它會顯示爲常規文件夾，但是如果我嘗試對其執行」cd「操作得到'CMD不支持作爲當前目錄的UNC路徑 –
