    EmbeddedResult result = new EmbeddedResult(attribute.getEmbeddable(), attribute.getAttributes().size());
    attribute.getAttributes().forEach(attr -> {
        Node sqlNode = context.getQualifierTranslator().translate(ExpressionFactory.dbPathExp(attr.getDbAttributePath()));
        context.addResultNode(sqlNode, true, null, null);
        result.addAttribute(attr);
    });
