Code to read fields from db for freightquote shipping module

[jimmie]

trying to add something like this in my shipping module

foreach ($products as $product) {
        $data = $db->Execute(
          "SELECT products_freightquote_length, products_freightquote_width, products_freightquote_height " .
          "FROM " . TABLE_PRODUCTS . " " .
          "WHERE products_id = " . (int)$product['id'] . " " .
          "LIMIT 1"
        );

To be read in this section

<Dimensions>
		<Length>ceil($data->fields['products_freightquote_length']),</Length>
		<Width>ceil($data->fields['products_freightquote_width']),</Width>
		<Height>ceil($data->fields['products_freightquote_height']),</Height>
		<Units>IN</Units>
	  </Dimensions>
    </RequestedPackageLineItems>
</RequestedShipment>
</RateRequest>";

what is the proper way
