php - MySQL Where Date (not datetime) as Week of year

Question

我有以下使用 Symfony2 的查询，我想转换 i.fechaInicio 是 date 字段 Y-m-d (2013-08-31 ) 到当前周数，以便我可以从当前周获取结果...

$now = new \DateTime();
$semana = $now->format('W'); // Week Number
$query = $this->getEntityManager()
->createQuery("
        SELECT i
        FROM PgeIncidenciasBundle:Incidencia i
        WHERE i.fechaInicio = :semana // This is wrong because compares
                                      // Y-m-d with W so no results found...
        ")
->setParameters(array(
    'semana' => $semana
))
;
try {
    return $query->getResult();
}
catch (\Doctrine\ORM\NoResultException $e)
{
    return null;
}

使用BETWEEN运算符(operator):

$from = new DateTime;
$from->setIsoDate($from->format('o'), $from->format('W'));
$to = clone $from;
$to->modify('+6 day');

$query = $this->getEntityManager()
    ->createQuery("
        SELECT i
        FROM PgeIncidenciasBundle:Incidencia i
        WHERE i.fechaInicio BETWEEN :from AND :to
    ")
    ->setParameters(array(
        'from' => $from->format('Y-m-d'),
        'to' => $to->format('Y-m-d'),
    ));
