Remarks
This method is used when updating database object or LOB columns. Any empty
object is one whose attributes are all NULL. An empty LOB is a LOB of length
zero. Before writing is allowed on a LOB whose value is NULL, an empty LOB must
first be committed to the database. For more information, see the Blob Write method and example.
