Mysql查詢刪除某些類別的woocommerce產品

Question

我們需要刪除大約 20.000 個屬於某個類別的產品。 我們想直接通過 mysql 來做到這一點。 通過該查詢，所有產品都會被刪除：

DELETE FROM wp_term_relationships WHERE object_id IN 
(SELECT ID FROM wp_posts WHERE post_type IN ('product','product_variation'));
DELETE FROM wp_postmeta WHERE post_id IN (SELECT ID FROM wp_posts WHERE post_type IN 
('product','product_variation'));
DELETE FROM wp_posts WHERE post_type IN ('product','product_variation');

我們如何才能刪除類別 XY 內的產品？

感謝幫助

Answer 1

這是一個查詢示例...

SELECT r*
     , p.*
     , m.*
  FROM wp_term_relationships r
  JOIN wp_posts p
    ON p.id = r.object_id 
  JOIN wp_postmeta m
    ON m.post_id = p.id 
 WHERE p.post_type IN ('product','product_variation');
