Laravel 5 QueryException in Connection.php line 673:

Question

我收到此错误：

SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not     match number of tokens (SQL: delete from `preferences` where `tenant_id` = 154 and     `setting_type` = Category and 1 = 1)

当我使用此功能时：

private function updateSettingsTable($request, $requestType, $settingType)
{
    $redundants = Preference::where('tenant_id', session('tenant'))->where('setting_type', $settingType)->delete();
}

并像这样称呼它：

$this->updateSettingsTable($request, 'categories', 'Category');

似乎Laravel在将其发送到查询之前删除了"类别"周围的引号。有什么想法吗？

试试这个：

private function updateSettingsTable($request, $requestType,$settingType)
{
  $redundants = Preference::where('tenant_id', session('tenant')) ->where('setting_type', "'".$settingType."'")->delete();
 }
