推荐答案
问题是这是 MySQL 特有的问题，因此 Doctrine 不会直接涵盖.
The problem is that this is a MySQL specific problem so it will not be directly covered by Doctrine.
正如评论所提到的，您需要为此编写一个 RawSQL 查询.这将是最简单的方法.
As a comment mentioned, you would need to write a RawSQL Query for this. This would be the easiest way.
如果您希望它更复杂且真正独立于数据库，请查看 Events 和它的可能性.在执行实际查询之前，您可以检查是否存在，如果存在，则采取相应措施.
If you want it more sophisticated and truely DB independent, look into Events and it's possibilities. Before the actual query is executed, you can check for an existence and if it exists, act accordingly.
一种独立于 ORM/PHP 的方式是编写一个存储过程/触发器来处理这个问题的数据库端.
An ORM/PHP independent way is to write a stored procedure/trigger that handles this problem database side.
