Oracle Error Message
SQL*Loader-00478: unable to continue due to missing filename for LOBFILE or SDF
Reason for the Error
The name for a LOBFILE or secondary data file is either missing or NULL for the current row. SQL*Loader is unable to continue loading since it can’t determine how to get the LOB for the next row.
Solution
Correct the data file so that there are valid values for all fields containing the names of LOBFILEs and secondary data files.
