如何在Oracle 11g系统上查找可用的目录对象？
我假设这些信息在 Oracle 元数据表中可用，但具体在哪里？
我需要 BFILENAME 正如这个答案：使用 PL/SQL 如何将文件的内容放入 blob 中？
我尝试过：
select * from all_objects where object_type ='DIRECTORY';
OWNER OBJECT_NAME
------------------------------ ------------------------------
SUBOBJECT_NAME OBJECT_ID DATA_OBJECT_ID OBJECT_TYPE
------------------------------ ---------- -------------- -------------------
CREATED LAST_DDL_TIME TIMESTAMP STATUS T G S
------------------- ------------------- ------------------- ------- - - -
NAMESPACE EDITION_NAME
---------- ------------------------------
SYS ORACLE_OCM_CONFIG_DIR
12689 DIRECTORY
2010-03-30 10:16:30 2011-01-10 12:49:39 2011-01-10:12:49:39 VALID N N N

SYS DATA_PUMP_DIR
12764 DIRECTORY
2010-03-30 10:16:43 2011-01-10 12:49:38 2011-01-10:12:49:38 VALID N N N

SYS XMLDIR

2010-03-30 10:29:37 2010-03-30 10:29:37 2010-03-30:10:29:37 VALID N N N

但根据输出时间戳，这些不是为我创建的目录。这也没有显示该对象的真实操作系统文件路径是什么。
I assume this information is available in Oracle metadata tables, but where exactly ?
I need the directory object for BFILENAME as in this answer: Using PL/SQL how do you I get a file's contents in to a blob?
I tried:
select * from all_objects where object_type ='DIRECTORY';
OWNER OBJECT_NAME
------------------------------ ------------------------------
SUBOBJECT_NAME OBJECT_ID DATA_OBJECT_ID OBJECT_TYPE

NAMESPACE EDITION_NAME

But based on the output timestamps these are not the dirs created for me. This also doesn't show what is the real OS filepath for the object.
