        the database. Cannot be called when on the insert row.
        The
        <code>refreshRow</code>
        method provides a way for an application to
        explicitly tell the SDBC driver to refetch a row(s) from the
        database. An application may want to call
        <code>refreshRow</code>
        when caching or prefetching is being done by the SDBC driver to
        fetch the latest value of a row from the database. The SDBC driver
        may actually refresh multiple rows at once if the fetch size is
        greater than one.
        All values are refetched subject to the transaction isolation
        level and cursor sensitivity. If
        <code>refreshRow</code>
        is called after calling
        <code>updateXXX</code>
        , but before calling
        <member scope="com::sun::star::sdbc">XResultSet::updateRow()</member>
        , then the updates made to the row are lost.
        Calling the method
        <code>refreshRow</code>
        frequently will likely slow performance.
