public CachedRowSet createCopySchema() throws SQLException {
        throw new UnsupportedOperationException();
    }
Creates a <code>RowSet</code> object that is a copy of
this <code>CachedRowSetImpl</code> object's table structure
and the constraints only.
There will be no data in the object being returned.
Updates made on a copy are not visible to the original rowset.
<P>
This helps in getting the underlying XML schema which can
be used as the basis for populating a <code>WebRowSet</code>.

@return a new <code>CachedRowSet</code> object that is a copy
of this <code>CachedRowSetImpl</code> object's schema and
retains all the constraints on the original rowset but contains
no data
@throws SQLException if an error occurs in generating the copy
of the <code>CachedRowSet</code> object
