Query product rating & comments/reviews count for category pages

[enigma32]

Using modified product comments and ratings modules, what I'm trying to do is pull the average rating and reviews count for display on the category page.. User would want to know rating and if there are reviews BEFORE they bother viewing the product

My shoddy SQL query only makes no products appear on category page anymore..

classes/Category.php -> getProducts function line 406

       SELECT p.*, pa.`id_product_attribute`, pl.`description`, pl.`description_short`, pl.`available_now`, pl.`available_later`, pl.`link_rewrite`, pl.`meta_description`, pl.`meta_keywords`, pl.`meta_title`, pl.`name`, i.`id_image`, il.`legend`, m.`name` AS manufacturer_name, tl.`name` AS tax_name, t.`rate`, cl.`name` AS category_default, DATEDIFF(p.`date_add`, DATE_SUB(NOW(), INTERVAL '.(Validate::isUnsignedInt(Configuration::get('PS_NB_DAYS_NEW_PRODUCT')) ?

       '.($id_supplier ? 'AND p.id_supplier = '.$id_supplier : '');

any help?
