Php Symfony查询出错：应为文本，得到'&引用'；

我有以下疑问：

$query = $em->createQueryBuilder()
            ->select('u.id, u.username, u.username_canonical, u.email, u.email_canonical, u.last_login, u.name, u.type, u.phone, u.site, u.agency, u.subtype, u.info, u.created_date, u.vip')
            ->from('ContrateAdminBundle:Fosuser', 'u')
            ->where('u.created_date BETWEEN "'.$fromdateaccounts.'" AND "'.$todateaccounts.'" ')                      
            ->getQuery();

$results = $query->getResult();

在Symfony中获取用户数据，但我得到以下错误：

[Syntax Error] line 0, col 223: Error: Expected Literal, got '"'
500 Internal Server Error - QueryException
1 linked Exception: QueryException »

我的查询输出是：

SELECT u.id, u.username, u.username_canonical, u.email, u.email_canonical, u.last_login, u.name, u.type, u.phone, u.site, u.agency, u.subtype, u.info, u.created_date, u.vip
FROM ContrateAdminBundle:Fosuser u
WHERE u.created_date BETWEEN "2014-08-04 13:29" AND "2014-10-30 13:29"

SQL中的字符串文字由单引号表示，而不是双引号表示，因此您必须将查询中的字符串分隔符替换为

”

：

$query = $em->createQueryBuilder()
            ->select('u.id, u.username, u.username_canonical, u.email, u.email_canonical, u.last_login, u.name, u.type, u.phone, u.site, u.agency, u.subtype, u.info, u.created_date,u.vip')
            ->from('ContrateAdminBundle:Fosuser', 'u')
            ->where('u.created_date BETWEEN \'${fromdateaccounts}\' AND \'{$todateaccounts}\'')                      
            ->getQuery();

---

您还可以使用Expr：

$queryBuilder = $em->createQueryBuilder();

...
->where($queryBuilder->expr()->between('u.created_date', $fromdateaccounts, $todateaccounts));

---

请使用参数。接受的答案可以生成SQL注入

    ->where('u.something = ?1')
    ->setParameter(1, '')

你试过用简单报价代替双报价吗？
