implementing “update if exists” in Doctrine ORM

Question

I am trying to INSERT OR UPDATE IF EXISTS in one transaction.

in mysql, I would generally use DUPLICATE KEY (\"UPDATE ON

Answer 1

According to https://www.vivait.co.uk/labs/updating-entities-when-an-insert-has-a-duplicate-key-in-doctrine this can be achieved with $entityManager->merge().

$entity = new Table();
$entity->setId(1);
$entity->setValue('TEST');

$entityManager->merge($entity);
$entityManager->flush();
