删除 Woocommerce 产品但保留类别

Question

我有一个使用 Woocommerce 插件运行的 Wordpress 网站。 我有大量产品需要删除，不幸的是，通过 Wordpress 后端执行此操作是一个非常耗时且令人沮丧的过程。

我一直在寻找一种通过 phpMyAdmin 删除产品的方法，并找到了以下内容

DELETE relations.*, taxes.*, terms.*
FROM wp_term_relationships AS relations
INNER JOIN wp_term_taxonomy AS taxes
ON relations.term_taxonomy_id=taxes.term_taxonomy_id
INNER JOIN wp_terms AS terms
ON taxes.term_id=terms.term_id
WHERE object_id IN (SELECT ID FROM wp_posts WHERE post_type='product');

DELETE FROM wp_postmeta WHERE post_id IN (SELECT ID FROM wp_posts WHERE post_type = 'product');
DELETE FROM wp_posts WHERE post_type = 'product';

这很好用，接受它也会删除我想保留的产品类别。

有没有办法删除所有 woocommerce 产品但使用 SQL 保留类别？

谢谢

Answer 1

就我而言，这个 MySQL 查询有帮助

-- Remove all product attributes from WooCommerce
DELETE FROM wp_terms WHERE term_id IN (SELECT term_id FROM wp_term_taxonomy WHERE taxonomy LIKE 'pa_%');
DELETE FROM wp_term_taxonomy WHERE taxonomy LIKE 'pa_%';
DELETE FROM wp_term_relationships WHERE term_taxonomy_id not IN (SELECT term_taxonomy_id FROM wp_term_taxonomy);

-- Delete all WooCommerce products and product variation
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');

-- Delete orphaned postmeta
DELETE pm FROM wp_postmeta pm
LEFT JOIN wp_posts wp ON wp.ID = pm.post_id
WHERE wp.ID IS NULL
