1. 通过dmp 导入导出，这种情况一般需要注意用户的命名空间

2. 通过sqlldr实现

a.新建导入控制文件 input.ctl

Load data
Characterset UTF8
Infile 'H:\POI\baidu.txt'
Append into table tbl_poi_baidu
fields terminated by ","
Optionally enclosed by '""'
Trailing nullcols
(POI_NAME,CLASS_ALL,ADDR,PHONE,TEL,LONGITUDE,LATITUDE,CITY,CITYCODE,PROVINCE,DISTRICT,STREET,STREENUMBER,CLASS_1,CLASS_2,CLASS_3,CLASS_4)

b.命令行窗口输入

sqlldr userid=sde/sde control=input.ctl log=log.out discard=discard.txt errors=1000000 

文件字符集要与Oracle服务等字符集一致，建议文件另存为UTF-8无BOM，导入文件内添加 Characterset UTF8 ，解决Oracle数据导入中文乱码：export NLS_LANG='SIMPLIFIED CHINESE_CHINA.AL32UTF8'

DOS环境下文件快速合并： copy *.csv newfile.txt
