How to compare datetime field from Doctrine2 with

Question

I want to get the items which were created today with by a QueryBuilder from Doctrine2. I want to compare the createdAt(Datetime) field with today parameter(Date). Is it possible to do that in one query?

$qb = $this->createQueryBuilder('i');
$qb->innerJoin('i.type', 'it');
$qb->andWhere('it.name = :type');
$qb->andWhere('i.createdAt < :today');
// i.createdAt == datetime and :today parameter is a date

Answer 1

It's rare that such a mature ORM does not provide the DATE function. However, to get a date out of a datetime field, you can apply the SUBSTRING function like this:

SELECT SUBSTRING(i.dateTimeField,1,10) FROM tableName i

Hope it helps!

Answer 2

It is also possible to use built-in function DATE_DIFF(date1, date2) which returns difference in days. Check docs

$result = $this->createQueryBuilder('l')
    ->where('DATE_DIFF(l.startDate, CURRENT_DATE()) = 0')

Answer 3

You have to add to your query QueryBuilder the today parameter.

$today = new \DateTime();
$qb->setParameter('today', $today->format('Y-m-d'));

With the QueryBuilder, you can compare dates to DateTime with the format 'Y-m-d'

Answer 4

There is better option than adding the doctrine extension for date.

First you need to get start-datetime and end-datetime :

$today_startdatetime = \DateTime::createFromFormat( "Y-m-d H:i:s", date("Y-m-d 00:00:00") );
$today_enddatetime = \DateTime::createFromFormat( "Y-m-d H:i:s", date("Y-m-d 23:59:59") );

Now use them in query :

$em = \Zend_Registry::get('em');
$qb_1 = $em->createQueryBuilder();
$q_1 = $qb_1->select('wsh')
    ->from('\Entities\wishes', 'wsh')
    ->where('wsh.created_at >= :today_startdatetime')
    ->andWhere('wsh.created_at <= :today_enddatetime');


$q_1->setParameter('today_startdatetime', $today_startdatetime);
$q_1->setParameter('today_enddatetime', $today_enddatetime);
$result= $q_1->getQuery ()->getResult ();

An easy solution would be to format the datetime accordingly

public function getWithStartingPremium(\DateTime $datetime)
{
    $qb = $this->createQueryBuilder('c');

    return $qb
        ->innerJoin('c.collegePremium', 'cp')
        ->where($qb->expr()->eq('cp.start', ':date'))
        ->setParameters(array(
            'date' => $datetime->format('Y-m-d'),
        ))
        ->getQuery()
        ->getResult();
}

Answer 6

one idea is to extract from the date: the year, month and day. And then

$qb->select('p')
   ->where('YEAR(p.postDate) = :year')
   ->andWhere('MONTH(p.postDate) = :month')
   ->andWhere('DAY(p.postDate) = :day');

$qb->setParameter('year', $year)
   ->setParameter('month', $month)
   ->setParameter('day', $day);

MONTH DAY, and YEAR you take out the DoctrineExtensions from

e.g.

DoctrineExtensions

This works for me. You only need the files: day.php, month.php and year.php.....

You get the month e.g.:

    $datetime = new \DateTime("now");
    $month = $datetime->format('m');
    echo $month;

Copy day.php, month.php and year.php to your bundle Xy\TestBundle\Dql Register the new functions in app\config.yml with

doctrine:


orm:
    auto_generate_proxy_classes: %kernel.debug%
    entity_managers:
        default:
            auto_mapping: true
            dql:
                datetime_functions:
                    month: Xy\TestBundle\Dql\Month
                    year: Xy\TestBundle\Dql\Year
                    day: Xy\TestBundle\Dql\Day
