ORA-34726: (NLSCHARSET06) CAUTION: String truncated during character set conversion from [string] to [string]
Cause: Some operation required a string to be converted into a different character set. The string required more bytes in the new encoding, and exceeded some byte limit on its allowable length, causing some characters to be removed from the end of the string.
Action: If the byte limit is due to using the ID datatype, consider using the CHAR datatype instead. If the byte limit is due to the limit of 4000 bytes per line of CHAR data, break the long line up into multiple lines.
