學說2更新多列？

Question

如何將同一個元組上的這兩個更新合併爲一個操作？

$q = $this->em->createQuery('update \Entity\UserEn u set u.last = :last where u.name = :name'); 
$q->setParameters(array(
    'last' => new \DateTime($newLast), 
    'name' => $theUser, 

)); 
$q->getResult(); 


$q = $this->em->createQuery('update \Entity\UserEn u set u.contribution = :contribution where u.name = :name'); 
$q->setParameters(array(
    'contribution' => $this->rContributionUser($theUser), 
    'name'   => $theUser, 

)); 
$q->getResult(); 

我覺得一個更新比2更新便宜。

用逗號分隔兩個任務：

$q = $this->em->createQuery('update \Entity\UserEn u set u.last = :last, u.contribution = :contribution where u.name = :name'); 
$q->setParameters(array(
    'last'   => new \DateTime($newLast), 
    'contribution' => $this->rContributionUser($theUser), 
    'name'   => $theUser, 
)); 
$q->getResult();
