Php 错误："；SQLSTATE[42000]：语法错误或访问冲突：1064您的SQL语法有错误&引用；。.env或PDO中的问题？

我正在修改其他人的代码，并得到一个

“SQLSTATE[42000]：语法错误或访问冲突：1064您有 SQL语法中的错误“错误”

我的第一个想法是我没有正确安装slim，但再次安装并没有任何区别。因此，问题可能出在.env文件或PDO中。有人能帮忙吗

PDO：

.env:

eventmodel的第一部分：

declare(strict_types=1);

namespace App\Model;

use DateTime;

class EventModel extends PdoModel
{
 public function getEvents() : array
 {
     $query = "SELECT e.id,e.name,e.description,e.event_manager_id,em.name as event_manager_name ,
     e.company_name,DATE_FORMAT(datetime,'%d-%m-%Y') as date,DATE_FORMAT(datetime,'%H:%i') as time,
      e.maximum_amount_of_guests as guests,
               FROM event e LEFT JOIN event_manager em ON (em.id = e.event_manager_id) ORDER BY date DESC";
     $statement = $this->getConnection()->prepare($query);
     $statement->execute();
     return $statement->fetchAll();
 }    

欢迎提出任何建议。我不知道问题出在哪里

SELECT e.id,e.name,e.description,e.event_manager_id,em.name as event_manager_name ,
     e.company_name,DATE_FORMAT(datetime,'%d-%m-%Y') as date,DATE_FORMAT(datetime,'%H:%i') as time,
      e.maximum_amount_of_guests as guests
               FROM event e LEFT JOIN event_manager em ON (em.id = e.event_manager_id) ORDER BY date DESC

您的查询中有语法错误。这个错误相当直截了当。您的env文件很好。

在您的查询中，在

FROM

正确的查询：

SELECT 
    e.id,
    e.name,
    e.description,
    e.event_manager_id,
    em.name as event_manager_name,
    e.company_name,
    DATE_FORMAT(datetime,'%d-%m-%Y') as date,
    DATE_FORMAT(datetime,'%H:%i') as time,
    e.maximum_amount_of_guests as guests
FROM event e 
LEFT JOIN event_manager em ON (em.id = e.event_manager_id) 
ORDER BY date DESC

查询中出现错误：

SELECT 
    e.id,
    e.name,
    e.description,
    e.event_manager_id,
    em.name as event_manager_name,
    e.company_name,
    DATE_FORMAT(datetime,'%d-%m-%Y') as date,
    DATE_FORMAT(datetime,'%H:%i') as time,
    e.maximum_amount_of_guests as guests
FROM event e 
LEFT JOIN event_manager em ON (em.id = e.event_manager_id) 
ORDER BY date DESC

这里有一个问题：

e.maximum_amount_of_guests as guests, // this will generate error
               FROM event e

1064

清楚地告诉您，您的查询not.env文件中存在问题

您的代码中有问题，但不在。错误消息是一个很好的故障排除工具。在您的例子中，它表示在事件的

附近有语法错误。查看您的查询，FROM前面有一个额外的逗号。问题应作为typo@JayBlanchard：嗨，你好，是的，你是对的，它的打字错误在将来不会有帮助，我添加了一些与服务器错误和1064有关的额外内容。非常感谢！这花了我好几天的时间。我在查询中找不到错误。我是PHP新手，Google告诉我.env文件中应该有问题。代码之前有一个.env问题，这给了我一个模拟错误。因此产生了混乱。谢谢！
e.maximum_amount_of_guests as guests, // this will generate error
               FROM event e
