在一个大文本中（超过1.5G），当有同时存在回车换行以及回车字符结尾时，如果换行结尾的量大于sqlldr默认缓冲1048576时候，会报错

在一个大文本中（超过1.5G），当有同时存在回车换行以及回车字符结尾时，如果换行结尾的量大于sqlldr默认缓冲1048576时候，会报错。

SQL*Loader-510: 数据文件 (XXX.txt) 中物理记录超过最大限制 (1048576)

SQL*Loader-2026: 加载因 SQL 加载程序无法继续而被终止。

网上搜很久，解决方法

修改 readsize — 读取缓冲区的大小 (默认 1048576) 修改为 20971520

但是还是报错

SQL*Loader-510: 数据文件 (XXX.txt) 中物理记录超过最大限制 (20971520)

SQL*Loader-2026: 加载因 SQL 加载程序无法继续而被终止。

这边简单分析下原因，sqlldr加载到我这边txt文本中第一行以回车换行符结尾，就默认所有行都以回车换行符结尾了，当加载到以换行符结尾的文本区域时由于换行结尾的行数过大，缓冲区无法装载而报错。

解决方法：

INFILE "xxx.txt" "str X'0A'"

0A代表换行符，即将换行符一起装载，相当于定义新行结尾符号。
