How to get an extra field along with the rest?

Question

Doctrine ORM

I'm trying to get a list of all elements and add to them a property of type COUNT (...) AS counter calculated in the database, and as a result it makes an array of nested values

[
  [
    [...данные из таблицы..],
    [counter: число]
  ]
]

And I want it to just add a value to the list of data. How to do it?

->addSelect('count(p.point) AS count')
