if I use

$TR = $entityManager->getRepository(Transaction::class);
    $cb = $TR->createQueryBuilder('t')
        ->select('DATE_FORMAT(t.time, "%d. %m. %y") AS date')
        ->distinct()
        ->getQuery();

The result query looks like “SELECT DISTINCT DATE_FORMAT(t.time, “%d. %m. %y”) AS date FROM Transaction t” and does not run, since the table name for entity Transaction is transactions.
I did declare

#[ORM\Entity]
#[ORM\Table(name: 'transactions')]

class Transaction
{...

in the class and also

$TR = $entityManager->getRepository(Transaction::class);
    $cb = $TR->findAll();
    var_dump($cb);

works like expected.

Any idea what I’m missing? Thanks a lot in advance for any hint!

Cheers
