PHP-如何扫描不存在的DynamoDb

我正在使用此git Repo使用Laravel DynamoDB

https://github.com/baopham/laravel-dynamodb

我想查询不存在

尝试过这没有用

$logs = $ShopperLogs->where('date', '>=', $from)->where('date', '<=', $to)->where('op_city_id', 'Not Exists')->get();

并尝试了这个,也没有用

$logs = $ShopperLogs->where('date', '>=', $from)->where('date', '<=', $to)->where('op_city_id', null)->get();

解决方法:

whereNull()和whereNotNull()

NULL and NOT_NULL only check for the attribute presence not its value
being null

  
  看到：
  http://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_Condition.html

$model->whereNull('name');
$model->whereNotNull('name');
