SQL to QueryBuilder - doctrine-orm

Question

first, sorry for bad English!
I try to convert this SQL (it's operational):
SELECT DISTINCT U.id
FROM User U
INNER JOIN Detail DE on U.id = DE.id_user
INNER JOIN matiere MA on U.id = MA.id_user
WHERE DE.ville = $var1
AND MA.matiere = $var2
in query builder.
I have try this:
$query = $repository->createQuerybuilder('U.id')
->from('User', 'U')
->innerJoin('Detail', 'DE', 'WITH', ' U.id = DE.id_user' )
->innerJoin('matiere', 'MA', 'WITH', 'U.id = MA.id_user')
->where('DE.ville = :ville')
->setParameter('ville', $ville)
->andWhere('MA.matiere = :matiere')
->setParameter('matiere', $matiere)
->distinct();
but I have this error:
"[Syntax Error] line 0, col 49: Error: Expected end of string, got '.' "
And when I try this:
$query = $repository->createQueryBuilder()
->select('U.id')
->from('User', 'U')
->innerJoin('Detail', 'DE', 'WITH', ' U.id = DE.id_user' )
->innerJoin('matiere', 'MA', 'WITH', 'U.id = MA.id_user')
->where('DE.ville = :ville')
->setParameter('ville', $ville)
->andWhere('MA.matiere = :matiere')
->setParameter('matiere', $matiere)
->distinct();
I have this error:
Warning: Missing argument 1 for Doctrine\ORM\EntityRepository::createQueryBuilder(),
I work with doctrine and symfony3.
Thanks for help.

This is like a syntax error , both the function of development in the query builder as the own instance of the query , try to make a debug and see how the SQL query is being built , syntax error possibly.
$qb = $repository->createQueryBuilder();
$query = $qb->getQuery();
$debug = $query->debug();
has a space between the strings [ ' U.id = DE.id_user ' ) ] , remove these spaces to try to surround the possible error;
or you can try make this way, probably work:
$query = $repository->createQueryBuilder(); <!--separte constructor this line-->
$query->select('U.id')
->from('User', 'U')
->innerJoin('Detail', 'DE', 'WITH', 'U.id = DE.id_user' ) <!--align this line-->
->innerJoin('matiere', 'MA', 'WITH', 'U.id = MA.id_user')
->where('DE.ville', ':ville') <!--separate this line-->
->setParameter('ville', $ville)
->andWhere('MA.matiere', ':matiere') <!--separate this line-->
->setParameter('matiere', $matiere)
->distinct()
->getQuery(); <!--add this line-->
$resp = $query->getResult(); <!--get the answer this line-->

In this line:
$query = $repository->createQuerybuilder('U.id')
You are trying to pass a object and method call instead of just a single parameter. That why the error about the dot.
Use this instead before the querybuilder to get the ID:
$id = U.id
or
$id = $U->getId();
then pass in parameter:
$query = $repository->createQuerybuilder($id )
...
Then you won't get the error: "[Syntax Error] line 0, col 49: Error: Expected end of string, got '.' "
