我想从Doctrine2获取由QueryBuilder创建的项目。我想将createdAt(Datetime)字段与今天参数(Date)进行比较。是否可以在一个查询中执行此操作?
$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

一个想法是从日期中提取:年,月和日。然后
$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,以及从
中取出DoctrineExtensions的年份e.g。
这对我有用。你只需要文件:day.php,month.php和year.php .....
你得到月份,例如:
$datetime = new \DateTime("now");
$month = $datetime->format('m');
echo $month;
将day.php,month.php和year.php复制到您的捆绑包Xy \ TestBundle \ Dql 使用
在app \ config.yml中注册新功能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

比添加日期的学说扩展名更好。
首先,你需要获得start-datetime和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") );
现在在查询中使用它们:
$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 ();

这种成熟的ORM很少提供DATE
功能。但是,要从日期时间字段中获取日期,您可以像这样应用SUBSTRING
函数:
SELECT SUBSTRING(i.dateTimeField,1,10) FROM tableName i
希望它有所帮助!

也可以使用内置函数DATE_DIFF(date1, date2)
来返回天数差异。查看docs
$result = $this->createQueryBuilder('l')
->where('DATE_DIFF(l.startDate, CURRENT_DATE()) = 0')

您必须向查询QueryBuilder添加today
参数。
$today = new \DateTime();
$qb->setParameter('today', $today->format('Y-m-d'));
使用QueryBuilder,您可以将日期与DateTime进行比较,格式为'Y-m-d'

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();
}
