Codeigniter 3, sqlite3: каскад построителя запросов удаления не работает ⇐ Php

[Anonymous]

В настоящее время я использую CodeIgniter-3.1.13 в качестве своей платформы и sqlite3 в качестве драйвера базы данных.
Я пытался удалить запись из своей базы данных, используя обычный построитель запросов на удаление, проблема в том, что ограничение внешнего ключа не работает. Я имею в виду, что когда я пытаюсь удалить определенные данные в родительской таблице, данные в дочерней таблице также не удаляются. Но когда я попытался удалить запись из родительской таблицы с помощью команды sql браузера БД, это сработало.
