如何在sqlldr中倒入多字符分隔符文件

今天有朋友询问：
我们...应用系统很多，它们之间要交换很多数据，目前是以文本方式交换，问题是文本的分隔符号是（|+|），为三个字符，主要是避免数据的混淆.....

这样的文件能够用sqlldr导入么?

我测试了一下，试验证明是可以的，sqlldr支持多字符分隔符文件导入。
首先看我的数据文件和控制文件:

[oracle@jumper tmp]$ cat data.ctl
load data
into table TEST
fields terminated by "|+|"
(
T_ID,
T_VOL
)
[oracle@jumper tmp]$ cat data.txt
20021228000000|+|00120000
20021228000000|+|00130000
20021228000000|+|00140000
20021||8000000|+|00140000
20021++8000000|+|00140000

[oracle@jumper tmp]$ sqlplus eygle/eygle

只作了简单验证，不知道复杂情况会不会有问题。
