     * level to support update, the cursor's {@code select} statement should be
     * of the form 'select for update'. If the 'for update' clause is
     * omitted, the positioned updates may fail.
     *
     * <P>The JDBC API supports this SQL feature by providing the name of the
     * SQL cursor used by a {@code ResultSet} object.
     * The current row of a {@code ResultSet} object
     * is also the current row of this SQL cursor.
     *

     * {@code SQLException} is thrown.
