Answer : Something like: $qb = $entityManager->createQueryBuilder(); $qb->select('count(account.id)'); $qb->from('ZaysoCoreBundle:Account','account'); $count = $qb->getQuery()->getSingleScalarResult(); Some folks feel that expressions are somehow better than just using straight DQL. One even went so far as to edit a four year old answer. I rolled his edit back. Go figure. Here is another way to format the query: return $repository->createQueryBuilder('u') ->select('count(u.id)') ->getQuery() ->getSingleScalarResult(); It's better to move all logic of working with database to repositores. So in controller you write /* you can also inject "FooRepository $repository" using autowire */ $repository = $this->getDoctrine()->getRepository(Foo::class); $count = $repository->count(); And in Repository/FooRepository.php public function count() { $qb = $repository-&g

Answer : You can't use select2 or react-select with react-native, because it's DOM based and so, it will work only in navigator, not in react-native The closest react-native equivalent I've found is react-native-multiple-select, you can find it on github at https://github.com/toystars/react-native-multiple-select or install it with npm i react-native-multiple-select Probably the closest to what you want that comes bundled with React Native is http://facebook.github.io/react-native/docs/picker.html The Picker component will give you a tumbler thing on iOS and a dropdown on Android Alternatively maybe this 3rd party component is closer to what you want: https://github.com/bulenttastan/react-native-list-popover From How to use React native select box
