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

创建测试表:

[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。

Why not try it before question?

不会有问题的，字段和记录都可以是多字符分隔的(从8I开始支持)， 我曾经试过文本字符串和图像混在一个文件中的，都可以的。
