sqluldr2的報錯日誌為： 0 rows exported at 2018-11-07 16:26:48, size 0 MB. 

ORA-24345: A Truncation or null fetch error occurred
 

sqluldr2的報錯日誌為：
ORA-00923: FROM keyword not found where expected

解決辦法：

預設的buffer太小，不夠存放大量資料

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

在sqluldr2命令中新增引數safe=yes，問題依然得不到解決。

將CLOB型別資料不做遷移，問題即解決，但這種只是基於欄位價值不高···············
