php - 将数据库迁移到新服务器时，MySQL 错误字段列表中的未知列(Windows)

Question

我将我的数据库从一台服务器转移到另一台服务器，在 Debug模式下，我在 Mysql 数据库中遇到了这个错误。

WordPress database error: [Unknown column 'tb.adult_price' in 'field list']

我想这就是它的开始

         $query="SELECT
                post_id,
                {$wpdb->prefix}st_tours.max_people,
                {$wpdb->prefix}st_order_item_meta.adult_number+{$wpdb->prefix}st_order_item_meta.child_number+{$wpdb->prefix}st_order_item_meta.infant_number as total_booked
            FROM
                {$wpdb->prefix}st_tours
            JOIN {$wpdb->prefix}st_order_item_meta ON {$wpdb->prefix}st_tours.post_id = {$wpdb->prefix}st_order_item_meta.st_booking_id
            AND {$wpdb->prefix}st_order_item_meta.st_booking_post_type = 'st_tours'
            WHERE
                1 = 1
            AND

我搜索我的 php 文件并找到了代码:

我不太了解 SQL 和数据库..

有什么办法可以解决吗？

Answer 1

这是关于您在 Windows 中的设置...某些设置不正确(SQL-PHP 版本 - IIS 或 Apache)...尝试更改 config.php

 define('WP_DEBUG', false); --> define('WP_DEBUG', true);

就像您在 Windows 中所做的那样，查看您的 SQL 错误是否也存在。

如果不尝试正确移动数据库，这意味着不要立即全部导入，而是使用 sql 命令 - 使用文本编辑器打开导出文件并复制粘贴 - 以确保数据库安装正确.. 之后检查设置以及你的删除错误。

这发生在我身上，是我的服务器设置错误。
