Question

如果有人有时间回答，请快速提问。当前查询效果很好，但我还需要获得订单总数和总运费。我知道由于连接，数字会被抛弃。

我知道我的数量和金额将是：

count(DISTINCT orders.id) AS num_orders,
SUM(orders.shipping_cost_ex_tax) AS shipping

我想我需要在原始选择中使用count和sum并在连接中处理其余部分，但是对于我的生活，我无法做到这一点。

任何帮助都会受到赞赏，即使它是“运行单独的查询”。谢谢大家。

当前查询：

SELECT 
    IF(products.categories LIKE '68', 'Shirts', 'Books') AS group_key,
    CONCAT(order_products.name) AS product_name,
    brands.name AS author,
    SUM(order_products.quantity) AS num_units,
    CASE WHEN products.sku LIKE '%-WB' THEN 'Combo'
        WHEN products.sku LIKE '%-BO' THEN 'Box'
        ELSE ''
    END AS item_type,
    SUM(IF(order_products.discount IS NULL, order_products.price_ex_tax, (order_products.price_ex_tax - order_products.discount))) AS income 
 FROM orders 
 INNER JOIN order_products ON order_products.bc_order_id = orders.bc_id
 INNER JOIN products ON order_products.bc_product_id = products.bc_id
 INNER JOIN brands ON products.brand_id = brands.bc_id 
 WHERE (orders.created_at BETWEEN '2012-01-28 00:00:00' and '2012-02-21 23:00:00') 
 GROUP BY group_key,
 case when products.brand_id = '68'
 then products.name
 else products.sku
 end

查看提供的评论，而不是在我面前展示您的完整架构。这样的事情会起作用吗？

Table Report  
(  
    id,  
    countOrders,  
    countSales,  
    countShipping,  
    countTax,  
    datePublished  
)   

Table SoldProducts  
(  
    id,  
    price,    
    tax,  
    shippingPrice,  
    datePurchased  
)

因此，您在此实例中要做的是通过从SoldProducts查询生成报告，然后您将保留生成的报告。

带有count，sum和group by的SQL查询
