Remarks
This setCharacterStream method is specified by the setCharacterStream method in the java.sql.PreparedStatement interface.
When the length is set to -1, a stream is allowed, but a specific length is not required. If the Reader passes a stream of a different length than what is specified, the JDBC driver will stop the update while it tries to preserve the connection and the current transaction.
