PHP Класс Google\Cloud\Datastore\Query\Query

Queries can be created either by using the builder pattern, or by providing a Query when creating this object. Example: use Google\Cloud\ServiceBuilder; $cloud = new ServiceBuilder(); $datastore = $cloud->datastore(); $query = $datastore->query(); $query->kind('Person'); $query->filter('firstName', 'Bob'); $result = $datastore->runQuery($query); Queries can also be constructed using a Query Object: $query = $datastore->query([ 'query' => [ 'kind' => [ [ 'name' => 'People' ] ], 'filter' => [ 'propertyFilter' => [ 'op' => 'EQUAL', 'property' => [ 'name' => 'firstName' ], 'value' => [ 'stringValue': 'Bob' ] ] ] ] ]); $result = $datastore->runQuery($query); Показать файл Открыть проект Примеры использования класса
