Oracle Error Message
ORA-38905: DML error logging is not supported for LONG column “string”
Reason for the Error
A DML Error Logging operation was attempted on a table which has a LONG, or LONG RAW column type, and the error logging table referred to the specified column.
Either do not use DML Error Logging on such a table or remove the offending column from the error logging table. The scalar columns can be logged, but not long column types.
