一、下载工具：

打开http://www.anysql.net/在其右边找到sqluldr2，然后点击：

二、下载后解压，有各种对应的版本，我们选择linux64位的：

三、将其放到你要执行的linux目录下，修改 $HOME 目录下.bash_profile 增加如下环境变量：

export LD_LIBRARY_PATH=$ORACLE_HOME/bin:$ORACLE_HOME/lib:/lib:/usr/lib

再用 ./sqluldr2_linux64_10204.bin 加上对应的参数执行就可以了。

先执行./sqluldr2_linux64_10204.bin可以看到其参数说明：

[oracle@localhost ~]$ ./sqluldr2_linux64_10204.bin

ncharset= national character set name of the target database.

parfile = read command option from parameter file

for field and record, you can use ‘0x‘ to specify hex character code,

\r=0x0d \n=0x0a |=0x7c ,=0x2c, \t=0x09, :=0x3a, #=0x23, "=0x22 ‘=0x27

下面举一下例子：

1、

./sqluldr2_linux64_10204.bin user=c##scott/scott@orcl query="select * from emp" file="emp.txt"

2、

./sqluldr2_linux64_10204.bin user=c##scott/scott alter="DISABLE PARALLEL QUERY;" sql=sql/n3.sql charset=AL32UTF8 record=0x0d0x0a file=emp.csv

3、

./sqluldr2_linux64_10204.bin parfile=parfiles/scott query="select * from emp" file=/home/yaokangjun/emp.txt

其中parfile=parfiles/scott为其当前目录parfiles配置文件scott，如scott为：

user=c##scott/scott@orcl

charset=ZHS16GBK

field=0X1F

record=0x0d0x0a

alter=set nls_date_format=‘yyyymmddhh24miss‘;
