The OLE DB Provider for Oracle exposes the ISequentialStream interface to support consumer access to Oracle LONG and LONG RAW data types as Binary Large Objects (BLOBs). The Read method on ISequentialStream allows the consumer to retrieve large amounts of data in manageable chunks.
The OLE DB Provider for Oracle storage objects are not blocking.
The length of data presented by a consumer-implemented storage object must be made known to this provider when the row accessor that references the storage object is created. The consumer must bind a length indicator in the DBBINDING structure used for accessor creation.
