从Woocommerce中删除重复的项目

Question

我在导入产品时遇到问题。现在有些产品是重复的。所有重复的产品都具有相同的标题和属性（collection_id）。还有很多重复的媒体文件。有没有办法删除重复的产品？至少我想删除产品。

我遇到了同样的问题，我确实遇到了。

1.- 在我的数据库中发现重复的产品（按 sku 搜索）与查询：

SELECT meta_value, count(*) AS total FROM wp_postmeta WHERE meta_key = '_sku' GROUP BY meta_value HAVING total > 1

2.- 我用这些 skus 创建了一个名为 wp_repeated 的新表：

CREATE TABLE wp_repeated AS SELECT meta_value, count(*) AS total FROM wp_postmeta WHERE meta_key = '_sku' GROUP BY meta_value HAVING total > 1

3.- 我从这些 skus 那里得到了 post_id：

SELECT p.ID FROM `wp_posts` as p INNER JOIN wp_postmeta as m on p.ID = m.post_id WHERE p.post_type IN ('product','product_variation') AND m.meta_key = '_sku' AND m.meta_value in (select meta_value from wp_repeated)

4.- 最后，从所有出现 post_id 的表中移除和删除：

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 p.ID FROM `wp_posts` as p INNER JOIN wp_postmeta as m on p.ID = m.post_id WHERE p.post_type IN ('product','product_variation') AND m.meta_key = '_sku' AND m.meta_value in (select meta_value from wp_repeated)); DELETE FROM wp_postmeta WHERE post_id IN ( SELECT p.ID FROM `wp_posts` as p INNER JOIN wp_postmeta as m on p.ID = m.post_id WHERE p.post_type IN ('product','product_variation') AND m.meta_key = '_sku' AND m.meta_value in (select meta_value from wp_repeated)); DELETE FROM wp_posts WHERE ID IN (SELECT p.ID FROM `wp_posts` as p INNER JOIN wp_postmeta as m on p.ID = m.post_id WHERE p.post_type IN ('product','product_variation') AND m.meta_key = '_sku' AND m.meta_value in (select meta_value from wp_repeated));

希望对你有帮助。问候。

TAKE CARE：这些查询会删除所有重复的产品。
