Doctrine \ DBAL \ DBALException：平台mssql在限制查询中不支持偏移值

Question

错误非常直接。我将Symfony 4和MSSQL Server用作具有以下配置的数据库服务器：

driver: 'sqlsrv'
url: 'mssql://username:password@host:1433/db'

当我使用setFirstResult（）时发生错误>

$entityManager->createQueryBuilder()->select('u')->from(UserEntity::class, 'u')
        ->setFirstResult(20)->setMaxResults(20)
        ->getQuery()->getArrayResult();
错误消息：

In AbstractPlatform.php line 3359:
[Doctrine\DBAL\DBALException]                                    
Platform mssql does not support offset values in limit queries.

对我有用的解决方案是手动使用原始查询：

$sql .= ' OFFSET ' . $offset . ' ROWS FETCH NEXT ' . $itemPerPage . ' ROWS ONLY';
但是此解决方案将终止使用ORM的目的，如果我切换到MySQL，它将无法使用。

如何解决上面的错误的正确方法？

错误非常直接。我将Symfony 4和MSSQL Server用作具有以下配置的数据库服务器：驱动程序：'sqlsrv'网址：'mssql：// username：password @ host：1433 / db'错误...
