【问题描述】：

我在下面有这个查询来删除所有 Woocommerce 订单。有谁知道我如何修改此查询以仅删除前 500 个订单。原因是我的系统超时。

DELETE FROM wp_woocommerce_order_itemmeta;
DELETE FROM wp_woocommerce_order_items;
DELETE FROM wp_comments WHERE comment_type = 'order_note';
DELETE FROM wp_postmeta WHERE post_id IN ( SELECT ID FROM wp_posts WHERE post_type = 'shop_order' );
DELETE FROM wp_posts WHERE post_type = 'shop_order';

【问题讨论】：

“第一”是什么意思？

【参考方案1】：

您可以使用 LIMIT 子句与您的 DELETE 查询就好了：

DELETE FROM wp_posts WHERE post_type = 'shop_order' LIMIT 500;
