📄 Description

from slack :

Hello, I'm playing with Doctrine ORM 3.5 and trying to use the SELECT NEW NAMED syntax to hydrate a DTO. I have a question about passing complete entity objects as constructor parameters; This works fine

$qb->select(sprintf('NEW %s(
    p.id,
    p.name,
    p.level,
    ...,
    t,           // Type entity works
    p.nickname
)', PokemonDetailView::class))
->leftJoin('p.type', 't')

But this doesn't

// Attempt 1: without AS
'NEW NAMED %s(..., t, ...)' 
// Error: Column name "t" does not match any property name

// Attempt 2: with AS
'NEW NAMED %s(..., t AS type, ...)'
// Error: Column name "t AS type" does not match any property name

// Attempt 3: only entity without AS, scalars with AS
'NEW NAMED %s(
    p.id AS id,
    p.name AS name,
    t,              // Entity without AS
    p.nickname AS nickname
)'
// Error: Column name "t" does not match any property name

According to the documentation, "you can only pass scalar expressions or other Data Transfer Objects to the constructor." However, I'm able to pass entity objects successfully with positional SELECT NEW. Is this limitation also applicable to SELECT NEW NAMED, or is there a specific syntax I'm missing for passing entity objects with named parameters?`
