【问题描述】：

我已尝试修复查询，但仍然无法正常工作

这是错误：

错误号：1064

您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以在第 3 行的“INSERT INTO user_notifications (id, usr_id, notification_message, sender`,”附近使用正确的语法

从 account_requests 中删除 usrs_id = '' AND account_requesting = '2'; INSERT INTO user_notifications（id, usr_id , NOTIFICATION_MESSAGE , 发送, show, 日期) VALUES (NULL, '', 'Successful account upgrade. You are now a Tutor', 'Codeg Account Wizard', 1, CURDATE()); INSERT INTO usrs_acc_type ( usrs_usr_id , account_type_type_id ) VALUES (, 2); UPDATE 交易SET ORDER_STATUS = 'Completed' WHERE usr_id = AND purchase_type = 'Account Upgrade' AND ORDER_STATUS = 'Pending' ANDitem` = '导师账号';

文件名：C:\Users\Supremekhaoz\Downloads\Dropbox\htdocs\codeg\system\database\DB_driver.php

行号：330

查询：

DELETE FROM account_requests WHERE `usrs_id` = '$usr_id' AND `account_requesting` = '$type_id'; 
            
INSERT INTO user_notifications (`id, `usr_id`, `notification_message`, `sender`, show, `date`) VALUES (NULL, '$usr_id', 'Successful account upgrade. You are now a $type', 'Codeg Account Wizard', 1, CURDATE()); 

INSERT INTO usrs_acc_type (`usrs_usr_id`, `account_type_type_id`) VALUES ($usr_id, $type_id);

UPDATE `transaction` SET `order_status` = 'Completed' WHERE `usr_id` = $usr_id AND `purchase_type` = 'Account Upgrade' AND `order_status` = 'Pending' AND `item` = '$type Account';

【问题讨论】：

查找 INSERT INTO user_notifications (`id, id 缺少 1 个引号

标签： mysql codeigniter

【解决方案1】：

如果您使用的是 codeigniter，为什么不尝试活动记录

$data = array(
   'id' => NULL ,
   'usr_id' => $usr_id ,
   'notification_message' => 'Successful account upgrade. You are now a '.$type,
   'sender' => 'Codeg Account Wizard',
   'show' => 1,
   'date' => time()
);

$this->db->insert('user_notifications', $data);

还要检查你的$usr_id 是否有价值，我认为它没有价值

【解决方案2】：

$this->db->where('usrs_id',$usr_id);
$this->db->where('account_requesting',$type_id);
$this->db->delete('account_requests ');

您可以使用此代码进行删除
