class MyEntity {
    #[PrimaryKey, AutoIncrement]
    public int $id;

    #[Indexed]
    public string $name;

    #[SqlDefault('whatever')]
    public string $defaulted;

    /** @var array<mixed> */
    public ?array $arrayValue;

    #[SqlDefault(DefaultConstant::CurrentTimestamp)]
    public DateTime $createdAt;

    #[SqlOnUpdate(DefaultConstant::CurrentTimestamp)]
    public ?DateTime $updatedAt;
}

$pdo = new PDO('sqlite::memory:');

$repository = new Repository($pdo, MyEntity::class);

$repository->createSchema();

$entities = [
    MyEntity::create(
        name: 'Bob',
        createdAt: new DateTime('2025-02-01 10:00:00'),
    ),
    MyEntity::create(

    ),
    MyEntity::create(
        name: 'Fred',
        arrayValue: ['a' => 'b'],
    ),
];

foreach ($entities as $entity)
{
    $repository->add($entity);
}

$entities = $repository->getAll();

var_dump($entities);

$entity = $repository->get(1);
$entity->name = 'Howard';

$updated = $repository->update($entity);

var_dump($updated);

$repository->delete($entity);
