BLOBs and OLE Objects

SQLOLEDB exposes the ISequentialStream interface to support consumer access to Microsoft® SQL Server™ ntext, text, and image data types as binary large objects (BLOBs). The Read method on ISequentialStream allows the consumer to retrieve large amounts of data in manageable chunks.

SQLOLEDB can use a consumer-implemented IStorage interface when the consumer provides the interface pointer in an accessor bound for data modification.
