 If you invoke the `setBlobAsBinaryStream`, `setClobAsAsciiStream`, or
 `setClobAsCharacterStream` method on the `LobCreator` returned from

 `DefaultLobHandler` uses the JDBC 4.0 variants of the set-stream methods without a
 length parameter. Otherwise, it passes the specified length on to the driver.
