Mysql 用于从订单项中提取SKU的SQL（Woocommerce-Wordpress）

我不知道如何从Posteta成功获取SKU元数据。。。请帮忙

---

如果我尝试加入Posteta表，我会得到一个错误，查询失败，站点会下降。。。因此，我必须停止错误的查询…

此查询对我有效：

select
'EU' as country,
pmo.post_date,
pmo.ID,
p.order_id,
p.order_item_id,
p.order_item_name,
p.order_item_type,

max( CASE WHEN pm.meta_key = '_product_id' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as productID,
max( CASE WHEN pm.meta_key = '_qty' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as Qty,
max( CASE WHEN pm.meta_key = '_variation_id' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as variationID,
max( CASE WHEN pm.meta_key = '_line_total' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as lineTotal,
max( CASE WHEN pm.meta_key = '_line_subtotal_tax' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as subTotalTax,
max( CASE WHEN pm.meta_key = '_line_tax' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as Tax,
max( CASE WHEN pm.meta_key = '_tax_class' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as taxClass,
max( CASE WHEN pm.meta_key = '_line_subtotal' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as subtotal,
max( CASE WHEN pm.meta_key = 'jackpot_product' and p.order_item_id = pm.order_item_id THEN pm.meta_value END ) as jprod

from

wpx7_woocommerce_order_items as p,
wpx7_woocommerce_order_itemmeta as pm,
wpx7_posts as pmo
 where order_item_type = 'line_item' and
 p.order_item_id = pm.order_item_id and
  p.order_id = pmo.id and  pmo.post_date > SUBDATE(CURRENT_DATE, 10)
 group by
p.order_item_id
