SELECT * FROM product LEFT JOIN product_category ON product.product_id = product_category.product_id WHERE (status=1 and brand_name in (16)) and product.type='Normal' GROUP BY product.product_id ORDER BY product.product_id DESC

Expression #78 of SELECT list is not in GROUP BY clause and contains nonaggregated column '' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by
