The IRowsetFastLoad interface exposes support for SQL Server memory-based bulk-copy operations. OLE DB Driver for SQL Server consumers use the interface to rapidly add data to an existing SQL Server table.
If you set SSPROP_ENABLEFASTLOAD to VARIANT_TRUE for a session, you cannot read data from rowsets subsequently returned from that session. When SSPROP_ENABLEFASTLOAD is set to VARIANT_TRUE, all rowsets created on the session will be of type IRowsetFastLoad. IRowsetFastLoad rowsets do not support rowset fetch functionality; therefore, data from these rowsets cannot be read.
