读取订单非常慢的mysql查询（联接和分组依据）

阅读订单的查询非常慢。我已经尝试了很多东西，但是无法获得更快的查询。查询和数据库表下方。当然，所有重要字段都有索引。我注意到按功能删除分组可以加快速度，但是对查询进行分组很重要。

有更好的方法来获取订单吗？提前致谢。

SELECT
orders.id AS orderId, orders.delivery_from, orders.delivery_to,
orders_products.product_id, orders_products.color_id, ,orders_products.size_id,
sum(orders_products.quantity) as quantity,
customers.id AS customerId, customers.name AS customerName,
products.name
FROM orders
    INNER JOIN orders_products ON orders_products.order_id=orders.id
    INNER JOIN customers ON customers.id=orders.customer_id
    INNER JOIN products ON orders_products.product_id=products.id
    LEFT JOIN orders_product_data ON orders_product_data.order_id=orders.id AND orders_product_data.product_id=orders_product.product_id AND orders_product_data.color_id=orders_product.color_id
WHERE orders.status='0' AND
(orders.delivery_from<='2014-05-05' AND orders.delivery_to>='2014-05-05') AND
((orders_products_data.delivery_from<='2014-05-05' || orders_products_data.delivery_to=0) AND (orders_products_data.delivery_from>='2014-05-05' || orders_products_data.delivery_to=0))
GROUP BY customer_id, product_id, color_id, size_id

顾客

CREATE TABLE IF NOT EXISTS `customers` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(90) NOT NULL DEFAULT '',
  PRIMARY KEY (`id`)
);

产品展示

CREATE TABLE IF NOT EXISTS `products` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` varchar(20) NOT NULL DEFAULT '',
  PRIMARY KEY (`id`)
);

命令

CREATE TABLE IF NOT EXISTS `orders` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `customer_id` int(11) NOT NULL,
  `delivery_from` date NOT NULL,
  `delivery_to` date NOT NULL,
  `status` int(1) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
);

订单产品

CREATE TABLE IF NOT EXISTS `orders_products` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `order_id` int(11) NOT NULL DEFAULT '0',
  `product_id` int(11) NOT NULL DEFAULT '0',
  `color_id` int(11) NOT NULL DEFAULT '0',
  `size_id` int(11) NOT NULL DEFAULT '0',
  `quantity` int(11) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`)
);

颜色数据。下面的表格针对order_id，product_id和color_id组合存储交货信息，因为不同颜色产品的交货可能会发生变化。

CREATE TABLE IF NOT EXISTS `orders_products_data` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `order_id` int(11) NOT NULL DEFAULT '0',
  `product_id` int(11) NOT NULL DEFAULT '0',
  `color_id` int(11) NOT NULL DEFAULT '0',
  `delivery_from` date NOT NULL,
  `delivery_to` date NOT NULL,
  PRIMARY KEY (`id`)
);
