Question

我试图在Oracle 11g中加载大型XML文件并将其解析到新表中（对此部分我有SQL查询），但是我无法在SQL * Loader控制文件中设置正确的设置。我对Oracle有点陌生，在在线搜索解决方案和Oracle说明后，无法解决我的问题，我正在寻求您的帮助。我正在使用Windows 10和SQL Developer 4.0.3.16运行查询以在Oracle中创建表。

上一个帖子中回答了这个问题，但是建议的解决方案对我不起作用（When trying to load a clob to an Oracle table, loading too many records），但是我无法使其工作。

我已经使用了上一个网页中的两个控制文件，而只有第一个控制文件对我来说有相同的问题（在多行中插入了相同的XML）我正在提示中运行此代码：

sqlldr rc_tables/xxuser@xx.xxx.xx.xx/euxxxx control='control_file.ctl' log = 'data_log.log'

控制文件：

LOAD DATA
CHARACTERSET UTF8
INFILE 'C:\Users\...\NVTPOI_03_MEX_9701_001.xml'
REPLACE
INTO TABLE LEAD_REPORTING_CLOB
TRAILING NULLCOLS
(
XML  LOBFILE(CONSTANT 'C:\...\NVTPOI_03_MEX_9701_001.xml') TERMINATED BY    EOF
)

我创建的表是：

CREATE TABLE "LEAD_REPORTING_CLOB" 
(SHARED_XML CLOB);

如果我使用第二种方法（上一篇文章中的解决方案），如果我决定运行它而不将FILENAME字段添加到表中，则会收到一条错误消息：

SQL * Loader-416：表LEAD_REPORTING_CLOB中的字段SHARED_XML的SDF子句引用了一个不存在的字段。

控制文件：

LOAD DATA
INFILE * 
REPLACE
INTO TABLE LEAD_REPORTING_CLOB
FIELDS TERMINATED BY ',' TRAILING NULLCOLS
(
SHARED_XML  LOBFILE(FILENAME) TERMINATED BY EOF
)
BEGINDATA
'C:\Users\ivcrespo\Documents\projects\2018\oracle\NVTPOI_CHL_9500_001.xml'

我还尝试了使用带有FILENAME char（100）字段的表的上一个控制文件，但是id并没有加载任何内容。

控制文件：

LOAD DATA
INFILE * 
REPLACE

INTO TABLE LEAD_REPORTING_CLOB
FIELDS TERMINATED BY ',' TRAILING NULLCOLS
(
FILENAME,
SHARED_XML  LOBFILE(FILENAME) TERMINATED BY EOF
)
BEGINDATA
'C:\Users\ivcrespo\Documents\projects\2018\oracle\NVTPOI_CHL_9500_001.xml'

有人可以帮助我设置此权限吗？我在网上找到的示例通常显示控制文件，而不显示创建的表。我创建的表中有错误吗？这将是XML文件第一个节点的示例（每个文件中可以包含数百个）：
