public void undoInsert() throws SQLException {

    }
Immediately removes the current row from this
<code>CachedRowSetImpl</code> object if the row has been inserted, and
also notifies listeners the a row has changed.  An exception is thrown
if the row is not a row that has been inserted or the cursor is before
the first row, after the last row, or on the insert row.
<P>
This operation cannot be undone.

@throws SQLException if an error occurs,
                        the cursor is not on a valid row,
                        or the row has not been inserted
