MySQL服务器已消失CakePHP中的错误

Question

我正在使用CakePHP 3.2

我的应用程序工作正常，但是从最近几天发出错误

  

错误：SQLSTATE [HY000]：常规错误：2006 MySQL服务器已经消失

     

SQL查询

     

SELECT Categories.id AS Categories__id，Categories.title   AS Categories__title，Categories.description AS   Categories__description，Categories.icon AS Categories__icon，   Categories.c_status AS Categories__c_status，Categories.created AS   Categories__created，Categories.modified AS Categories__modified   FROM categories类别WHERE Categories.c_status = 1

和建议

 If you are using SQL keywords as table column names, you can enable identifier quoting for your database connection in config/app.php.

我尝试在app.php中启用标识符，然后也是同样的错误。

生成的查询的源代码

$menu_categories = $this->Categories->find('all', [
    'conditions' => [
      'Categories.c_status' => 1,
    ],
    'contain' => [
      'Subcategories.ProductTypes' => [
        'conditions' => [
          'ProductTypes.status' => 1,
        ],
      ],
      'CategoryBanners' => [
        'conditions' => [
          'CategoryBanners.status' => 1,
        ],
      ],
    ],
]);
$this->set('menu_categories', $menu_categories);

导致错误的原因是什么？

Answer 1

我遇到了此错误，事实证明是数据库的“ max_allowed_pa​​cket”设置存在问题。我的矿山从默认的增加到16MB，它解决了我的问题。需要检查并试验一下您还是其他任何人的错误。
