Можем ли мы ограничить «уровень безопасности» при обмене данными по протоколу безопасного канала (SCP) 02?

Я рекомендую хранить данные по-другому. Используйте один атрибут для «vacationStart» и один для «vacationEnd». All all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all all будет использовать запрос:

var query = firebase.database().ref('dinousaurs').orderByChild('vacationStart').equalTo('2016-12-20');
