    if (!(other instanceof Table))
        return false;
    Table table = (Table) other;
    if (table.size() != this.size())
        return false;
    QueryIterator qIter1 = iterator(null);
    QueryIterator qIter2 = table.iterator(null);
    try {
        for (; qIter1.hasNext(); ) {
            Binding bind1 = qIter1.nextBinding();
            Binding bind2 = qIter2.nextBinding();
            if (!BindingBase.equals(bind1, bind2))
                return false;
        }
        return true;
    } finally {
        qIter1.close();
        qIter2.close();
    }
}

    Table x1 = joinMaterialize(joinKey, left, right, conditions);
    assertNotNull("Null table from join (" + msg + ")", x1);
    if (false)
        print(msg, joinKey, left, right, conditions, expectedResults, x1);
    check("Results not equal (" + msg + ")", joinKey, left, right, conditions, expectedResults, x1);
}

    Table tbl = opTable.getTable();
    boolean process = false;
    for (Var v : tbl.getVars()) {

        Iterator<Binding> iter = tbl.rows();
        while (iter.hasNext()) {
            retTbl.addBinding(rewrite(iter.next()));
        }
        push(OpTable.create(retTbl));
