在Woocommerce中删除重复的导入订单

标签： php mysql sql wordpress orders

我在Woocommerce中有重复的订单，我想删除它们以仅保持唯一的清洁账簿。

我不擅长SQL，我编写了此请求，但是当有重复项时，它会列出两个重复项。

SELECT *
FROM `wp_posts` 
WHERE post_type = 'shop_order' AND post_status = 'wc-completed' 
GROUP BY post_date 
HAVING count(*) > 1 
ORDER BY `wp_posts`.`post_date` DESC

这给了我307个结果。

如何编写正确的请求以删除重复项并仅保留唯一订单？

样本数据：

编辑： 

SELECT DISTINCT post_date FROM `wp_posts` WHERE post_type = 'shop_order' AND post_status = 'wc-completed'

给我614个结果，是前一个请求的两倍。

WordPress：5.0
Woocommerce：3.5.2

首先，如果您不知道，woocommerce订单数据位于四（4）个表中：

  • wp_posts
  • wp_postmeta
  • wp_woocommerce_order_items
  • wp_woocommerce_order_itemmeta

因此以下挂钩函数使用WPDB类和方法。它将：

  1. 在一个查询中获取所有重复的订单ID （最低ID）（搜索通常是唯一的重复的订单密钥）
  2. 在一个查询中删除所有重复的查询订单。

但是请务必始终进行数据库备份。

代码可以在任何前端页面加载 （使用后将其删除）中一​​口气完成这项工作：

add_action( 'template_redirect', 'progressive_delete_duplicated_orders' );
function progressive_delete_duplicated_orders() {
    global $wpdb;

    // Get duplicated orders (smaller ID)
    $duplicated_orders = (array) $wpdb->get_col("
        SELECT p.ID, pm.meta_value, COUNT(*) as c
        FROM {$wpdb->prefix}postmeta as pm
        INNER JOIN {$wpdb->prefix}posts as p ON p.ID = pm.post_id
        WHERE p.post_status = 'wc-completed'
        AND pm.meta_key = '_order_key'
        GROUP BY pm.meta_value
        HAVING c > 1
    ");

    if( sizeof($duplicated_orders) == 1 )
        $where_clause = 'WHERE p.ID = ' . reset($duplicated_orders);
    elseif( sizeof($duplicated_orders) > 1 )
        $where_clause = 'WHERE p.ID IN (' . implode( ',',$duplicated_orders ) . ')';
    else return; // Exit

    // Delete duplicated Orders data everywhere
    $wpdb->query("
        DELETE p, pm, woi, woim
        FROM {$wpdb->prefix}posts as p
        INNER JOIN {$wpdb->prefix}postmeta as pm ON p.ID = pm.post_id
        INNER JOIN {$wpdb->prefix}woocommerce_order_items as woi ON p.ID = woi.order_id
        INNER JOIN {$wpdb->prefix}woocommerce_order_itemmeta AS woim ON woi.order_item_id = woim.order_item_id
        $where_clause
    ");
}

代码进入您的活动子主题（或活动主题）的function.php文件中。经过测试和工作。

  

重复的订单将在第一个前端页面加载时被删除。因此，之后您可以删除或注释代码。

尝试删除联接，以最大ID任意保留记录：

DELETE
FROM wp_posts
WHERE post_type = 'shop_order' AND post_status = 'wc-completed' AND
      ID NOT IN (SELECT ID
                 FROM (SELECT MAX(ID) AS ID FROM wp_posts
                       GROUP BY post_date, post_author) t);

如果您只想查看删除了逻辑重复项的帖子，请尝试：

SELECT w1.*
FROM wp_posts w1
INNER JOIN
(
    SELECT post_date, post_author, MAX(ID) AS max_id
    FROM wp_posts
    WHERE post_type = 'shop_order' AND post_status = 'wc-completed'
    GROUP BY post_date, post_author
) w2
    ON w1.post_date = w2.post_date AND
       w1.post_author = w2.post_author AND
       w1.ID = w2.max_id
WHERE w1.post_type = 'shop_order' AND w1.post_status = 'wc-completed'
