mysql - Woocommerce 通过自定义查询获取产品

Question

这是基于 WordPress 和 WooCommerce 并处理 post 和 post_meta 表

我必须获取所有具有meta_key =“_shop”和meta_value =“yes”的产品ID

典型条件:

如果元键和元值与父产品匹配，则其所有变体也必须包括。

如果元键和元值未与父级一起行进，但其变体具有元键和元值匹配，则仅返回变体。

Product(#18)(simple):           _shop = 'yes'
Product(#19)(variable):         _shop = 'yes' (Parent is Yes)
       Product(#20)(variation): _shop = 'yes'
       Product(#21)(variation): _shop = 'no'
       Product(#22)(variation): _shop = 'no'
Product(#23)(simple):           _shop = 'yes'
Product(#24)(variable):         _shop = 'no'  (parent is no)
       Product(#25)(variation): _shop = 'no'
       Product(#26)(variation): _shop = 'yes' (Only this variation)
       Product(#20)(variation): _shop = 'no'

我需要的 IDS:

#18 #19 #20 #21 #22 #23 #26

Answer 1

    select  productID from your_table
   where meta_key = "_shop" and meta_value = "yes"
