оптимизация запроса на хостинге

Recommended Posts

Требуется просто выполнить оптимизация, так как сайт нагружает хостинг, медленные логи вот 

 

Нагрузка: 407
SELECT p.product_id, (SELECT AVG(rating) AS total FROM oc_review r1 WHERE r1.product_id = p.product_id AND r1.status = NNN GROUP BY r1.product_id) AS rating, (SELECT price FROM oc_product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = NNN AND pd2.quantity = NNN AND ((pd2.date_start = SSS OR pd2.date_start < NOW()) AND (pd2.date_end = SSS OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT NNN) AS discount, (SELECT price FROM oc_product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = NNN AND ((ps.date_start = SSS OR ps.date_start < NOW()) AND (ps.date_end = SSS OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT NNN) AS special FROM oc_product p LEFT JOIN oc_product_description pd ON (p.product_id = pd.product_id) LEFT JOIN oc_product_to_store p2s ON (p.product_id = p2s.product_id) WHERE pd.language_id = NNN AND p.status = NNN AND p.date_available <= NOW() AND p2s.store_id = NNN AND p.manufacturer_id = NNN GROUP BY p.product_id ORDER BY p.sort_order ASC, LCASE(pd.name) ASC LIMIT NNN,NNN

Запрос конечно не идеальный но если такой запрос " нагружает хостинг" то меняйте этот хостинг на нормальный.

Пишите в личку.
Вам глобальная оптимизация нужна. А не запрос.
Запросы индивидуально - не оптимизируются.
Оптимизируется в целом база.
