sqluldr2的报错日志为： 0 rows exported at 2018-11-07 16:26:48, size 0 MB. 

ORA-24345: A Truncation or null fetch error occurred

sqluldr2的报错日志为：
ORA-00923: FROM keyword not found where expected

解决办法：

默认的buffer太小，不够存放大量数据

safe = use large buffer to avoid ORA-24345 error (Yes|No)

在sqluldr2命令中添加参数safe=yes，问题依然得不到解决。

将CLOB类型数据不做迁移，问题即解决，但这种只是基于字段价值不高···············
