Oracle Error Message
ORA-38904: DML error logging is not supported for LOB column “string”
Reason for the Error
A DML Error Logging operation was attempted on a table which has a CLOB, NCLOB, or BLOB column type, and the error logging table referred to the specified column.
Solution
Either do not use DML Error Logging on such table or remove the offending column from the error logging table. The scalar columns can be logged, but not LOB column types.
