Doctrine join WITH vs WHERE - join

Question

I'm joining multiple tables and I found two solution. I can't ready figure out what is the diference. Can anyone tell me?
Solution 1:
$query = $entityManager->createQuery("
SELECT m FROM Model m
JOIN m.battery b
JOIN m.camera c
JOIN m.connectivity co
JOIN m.hardware h
JOIN m.screen s
JOIN m.sensor se
WHERE b = m.battery
AND c = m.camera
AND co = m.connectivity
AND h = m.hardware
AND s = m.screen
AND se = m.sensor"
);
Solution 2:
$query = $entityManager->createQuery("
SELECT m FROM Model m
JOIN m.battery b
WITH m.battery = b
JOIN m.camera c
WITH m.camera = c
JOIN m.connectivity co
WITH m.connectivity = co
JOIN m.hardware h
WITH m.hardware = h
JOIN m.screen s
WITH m.screen = s
JOIN m.sensor se
WITH m.sensor = se
");

Answer 1

You are writing DQL and you should not confuse it with SQL. In a DQL query join you don't need to add id fields explicitly to the join Doctrine takes care of it for you.
"SELECT m FROM Model m JOIN m.battery b" is sufficient.
to fetch-join add b to your select clause:
"SELECT m, b FROM Model m JOIN m.battery b"
If you want to join only batteries with a certain property, that is when you need to use the WITH clause in your DQL. For example join only batteries who's battery status is empty:
"SELECT m, b FROM Model m JOIN m.battery b WITH b.status = 'empty'"
Check the documentation on DQL joins for more information.

Answer 2

From what i have read i can say:
When you use Where instead of On in join, there is one difference, On will apply before selection and Where will apply after the selection process by join. WITH is similar to On clause which lets you specify another condition in addition to On.
So I think when you use With, It will work like ON but Where will eliminate the result after selection by Join.
