Doctrine ORM: Is it possible to not map entire objects?

Question

Doctrine ORM

The task is as follows: to read a couple of columns from a table into a database (PostgreSQL) using Doctrine.
Question: Is it possible to do this using an ORM? At the same time, I do not want (do not need to) read all the columns, only a few values ​​are needed.
Clarification: in the future, it may be necessary not only to read from this table, but also to write to it.

Answer 1

is it possible not to map objects entirely?

You can forget about crutches with mapping some object fields, and describe separate DTO classes with the necessary fields.

ps Entity when using DataMapper != label in the database.
