使用SQL创建WooCommerce分析报告

Question

我最近刚转移到WooCommerce平台，需要在MySQL中构建SQL来运行自己的分析报告。例如，我需要显示最近30天内每个国家/地区每个sku的销售总数的报告。我浏览了“ wp_posts”，“ wp_postmeta”之类的表，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SQL更具挑战性。

Answer 1

最终由我自己构建了SQL。希望它对不想使用现成的分析解决方案或需要自定义报告的其他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;
