The IBM DB2 EE external loader cannot load LOB data, such as Blob, Clob, or Dbclob data. When you run a session that uses the IBM DB2 EE external loader and the source contains LOB data, the external loader successfully loads the remaining data to the target depending on the following mapping configurations:
LOB ports are unconnected.
The external loader successfully loads all remaining data to the target.
LOB ports are connected.
When loading to a database version 8.x, the external loader loads the LOB data as NULL and correctly loads the remaining data. When loading to a database version 9.x, the external loader does not load any data. It logs rejected rows in the external loader log.
