The USING request modifier supports passing LOBs to the Vantage platform. The documentation for each Vantage-supported API specifies how this functionality is presented to the application.
Deferred and locator modes defer the transfer of data between client and server, transmitting non-LOB data separately from LOB data. The appropriate deferred mode depends on the application. Neither deferred or locator mode passes the entire LOB field with the non-LOB data from a row.
