错误描述：Character data loss in NCHAR/CHAR conversion

错误原因：

bash
When character set conversion happened between CHAR and NCHAR either implicitly or explicitly, some characters were lost due to no mapping characters in the destination character set.

解决方法：

bash
Ensure that all the characters can be mapped to characters in the destination character set or set NLS_NCHAR_CONV_EXCP to be FALSE.1111
