get number of user connected lastweek (symfony - sql) - sql

Question

I want to know the number of users logged in the last week from current day, that's why I try with this:
class UserRepository extends EntityRepository
{
public function findNumberLastWeek(){
$dql = "SELECT count(p) FROM UserBundle:User p WHERE p.lastLogin >= 'DATEADD(day,-7, GETDATE())'";
return $this->getEntityManager()
->createQuery($dql)
->getSingleScalarResult();
}
but does not work :(

Answer 1

I used this to do a similar feature in my app (counting user which were connected last day) :
/**
* Get the number of users which were connected between two dates
* #param startDate $
* #param endDate $
* #return array
*/
public function countUsersConnectedBetweenDate($startDate, $endDate) {
$qb = $this->createQueryBuilder('u');
$qb
->select('COUNT(u) as numberConnectedUsersLastDay')
->where('u.lastLogin BETWEEN :startDate AND :endDate')
->setParameter("startDate", $startDate)
->setParameter("endDate", $endDate);
return $qb->getQuery()->getSingleScalarResult();
}
and in the controller (it's only to get last day connection) :
$em = $this->getDoctrine()->getManager();
$startYesterday = new \DateTime();
$startYesterday->modify('yesterday');
$endYesterday = new \DateTime();
$endYesterday->modify('1 second ago');
$countConnectedUsersLastDay = $em->getRepository(User::class)->countUsersConnectedLastDay($startYesterday, $endYesterday);
You can adjust the two dates to match what you want, I've not tested it but you can try something like that :
$em = $this->getDoctrine()->getManager();
$lastWeek = new \DateTime();
$lastWeek->modify('-1 week');
$now = new \DateTime();
$countConnectedUsersLastDay = $em->getRepository(User::class)->countUsersConnectedLastDay($lastWeek, $now);
I hope that will help you.

Answer 2

lastLogin should be a DATE type
Try the following: p.lastLogin <= DATE_ADD(CURRENT_DATE(), -7, 'day')
