dql

here we got a positional parameter:

SELECT 
u 
FROM ForumUser u 
WHERE u.id = ?1

and here a named parameter:

SELECT 
u 
FROM ForumUser u 
WHERE u.username = :name

this is DQL (doctrine query language) but i think the concept is the same.

could someone please explain what these mean and do?
