如何通过一个查询更新两行？

Question

我有一张这样的表：

// Answers
+----+---------+-----------------+-------------+
| id |  answer | accepted-answer | question_id |
+----+---------+-----------------+-------------+
| 1  | answer1 | null            | 1           |
| 2  | answer2 | 1               | 1           |
| 3  | answer3 | null            | 1           |
+----+---------+-----------------+-------------+

现在我正在尝试更改accepted-answer。我想要输出：

+----+---------+-----------------+-------------+
| id |  answer | accepted-answer | question_id |
+----+---------+-----------------+-------------+
| 1  | answer1 | null            | 1           |
| 2  | answer2 | null            | 1           |
| 3  | answer3 | 1               | 1           |
+----+---------+-----------------+-------------+

注意：我只有新的ID （新接受的答案的ID，而不是旧答案），在上面的示例中为$id=3。我在上面的示例中也有question_id $question_id=1。

我可以通过以下两个独立的查询来实现：

UPDATE Answers SET accepted_answer = null WHERE question_id = :question_id;

和

UPDATE Answers SET accepted_answer = 1 WHERE id = :id;

现在我想知道，我能在同一时间和一次查询中做到这一点吗？
