ORA-12713

Character data loss in NCHAR/CHAR conversion

Cause

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.


Action

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