php - Woocommerce WP - 从 post_type = shop_order | 获取 _sku 值SQL查询

Question

Woocommerce 在 wp_posts 中有两种类型的 post_type，“产品”和“< em>shop_order'。

根据shop_order ID，我可以在哪里获取_sku？ wp_postmeta 具有 _sku，它直接连接到 post_type = 'product'而不是 post_type = 'shop_order'。到目前为止有这个:

SELECT 
    oi.order_item_id,
    oi.order_item_name,
    oi.order_item_type,
    oi.order_id,
    max( CASE WHEN oim.meta_key = '_line_subtotal' and oim.order_item_id = oi.order_item_id THEN oim.meta_value END ) as _line_subtotal,
    max( CASE WHEN oim.meta_key = '_line_total' and oim.order_item_id = oi.order_item_id THEN oim.meta_value END ) as _line_total,
    max( CASE WHEN oim.meta_key = '_product_id' and oim.order_item_id = oi.order_item_id THEN oim.meta_value END ) as _product_id,
    max( CASE WHEN oim.meta_key = '_variation_id' and oim.order_item_id = oi.order_item_id THEN oim.meta_value END ) as _variation_id,
    max( CASE WHEN oim.meta_key = '_qty' and oim.order_item_id = oi.order_item_id THEN oim.meta_value END ) as _quantaty
FROM
    wp_woocommerce_order_items oi INNER JOIN
    wp_woocommerce_order_itemmeta oim on oi.order_item_id = oim.order_item_id
where oi.order_id=:order_item
    group by oi.order_item_id
    ");
$sth2->bindParam(':order_item', $_GET["order"], PDO::PARAM_STR);
$sth2->execute();

如何在此 SQL 查询中打印 _sku 值？ shop_order 到 product 的原始页面 ID 的连接在哪里 post_type = 'product '

_sku 值位于 wp_postmeta 中:

post_id = where wp_post.ID (which is the ID of the product, not the shop_order)
meta_key = _sku
meta_value = my_sku_value_here

以下是查找特定产品的 woocommerce 订单的查询:

select ord.ID
from wp_posts prd
join wp_woocommerce_order_itemmeta om on om.meta_key = '_product_id' and om.meta_value = prd.ID
join wp_woocommerce_order_items o on o.order_item_id = om.order_item_id
join wp_posts ord on ord.ID = o.order_id
where prd.ID = [Specific product ID]
