        <p>
        The insert row is a special row associated with an updatable
        result set. It is essentially a buffer where a new row may
        be constructed by calling the
        <code>updateXXX</code>
        methods prior to
        inserting the row into the result set.

        a result set must be given a value each time this method is
        called before calling
        <code>insertRow</code>
        . The method
        <code>updateXXX</code>
        must be called before a
        <code>getXXX</code>
        method can be called on a column value.
