I can't seem to find a way to do this using the entity itself. I have solved this now by utilizing a regular DQL which does increment, and update model/entity with result.

我似乎找不到用实体本身来做这个的方法。我现在已经通过使用一个增量的常规DQL解决了这个问题，并使用结果更新模型/实体。

It won't lead to the exact same query, but maybe this is what you are looking for?

它不会导致完全相同的查询，但也许这就是您要寻找的?

class MyEntity {
    private $field;

    public function incrementField() {
        $this->field++;
    }
}
