1055 - Expression #2 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'duraflex_store.rd.reviews_text' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

select r.reviews_id, rd.reviews_text as reviews_text, r.reviews_rating, r.date_added, p.products_id, pd.products_name, p.products_image, r.customers_name from reviews r, reviews_description rd, products p, products_description pd where p.products_id = '261899' and p.products_model = r.products_model and r.reviews_id = rd.reviews_id and p.products_id = pd.products_id and r.reviews_status=1 and r.products_id = p.products_id group by r.reviews_id order by r.reviews_id DESC
