使用pl / sql如何打开目录？

Answer 1

This is only valid for Oracle 10g+ (lots of info in the comment here) :

DECLARE

  pattern VARCHAR2(1024) := 'C:\temp\*';
   ns VARCHAR2(1024);

BEGIN
  SYS.DBMS_BACKUP_RESTORE.searchFiles(pattern, ns);

  -- List files in the directory
  FOR each_file IN (SELECT FNAME_KRBMSFT AS name FROM X$KRBMSFT) LOOP
    DBMS_OUTPUT.PUT_LINE(each_file.name);
  END LOOP;

END;
/

请记住，您将需要具有DBA特权才能写入文件系统，或者拥有愿意授予您这些特权的DBA（在许多环境中是不太可能的）。
