mysql - 使用 SQL 创建 WooCommerce 分析报告

Question

我最近刚搬到 WooCommerce 平台，需要在 MySQL 中构建 SQL 来运行我自己的分析报告。例如，我需要显示过去 30 天内每个国家/地区每个 SKU 的销售总数的报告。 我研究了“wp_posts”、“wp_postmeta”等表，发现产品和订单中的大多数字段都是基于记录的，而不是基于列的，这使得 SQL 更具挑战性。

Answer 1

终于自己构建了SQL。希望它对其他不想使用开箱即用的分析解决方案或需要自定义报告的 WooCommerce 用户有用。

SELECT 
    sku, count(1)
FROM 
    wp_woocommerce_order_items oi, -- orders table
    wp_posts p, -- woocommerce use posts to keep metadata on the order
    wp_postmeta pm, -- we use this table to filter the completed orders
    wp_postmeta pm1, -- we use this table again for getting the shipping country info
    wp_woocommerce_order_itemmeta oim, -- use this table to get product ids from orders
    (SELECT p.id as product_id, meta_value as sku FROM wp_posts p, wp_postmeta pm  where 
        post_type='product' and post_status='publish' 
        and meta_key='_sku' 
        and p.id=pm.post_id) as sku_table -- building temp sku table from published products that defines relationship between product id and sku
WHERE 
    oim.meta_value=sku_table.product_id AND
    oi.order_id=p.ID AND 
    p.id=pm.post_id AND 
    pm.meta_key='_paid_date' AND  -- here we make sure that the order was completed 
    p.id=pm1.post_id AND 
    order_item_type='line_item' AND -- get only line items but not tax or shipping 
    oi.order_item_id=oim.order_item_id AND
    oim.meta_key='_product_id'  AND
    post_date>'2014-01-01' AND -- limits the report date
    pm1.meta_key='_shipping_country' AND -- get shipping country 
    pm1.meta_value='US' -- limits the country
GROUP BY sku
ORDER BY sku;
