按字符串的长度排序

Question

有没有办法按Title字段中包含的字符串的长度来命令此查询？

    $query = $this->getEntityManager()
        ->createQuery('
    SELECT b FROM AcmeTestBundle:Blog b
    WHERE b.Title LIKE :title'
    )->setParameter('title','%'.$title.'%');

ORDER BY b.Title.length() 似乎不起作用.

Answer 1

是的,试试吧:

$query = $this->getEntityManager()->createQuery('SELECT LENGTH(b.Title) l, b FROM AcmeTestBundle:Blog b WHERE b.Title LIKE :title ORDER BY l')->setParameter('title','%'.$title.'%');
