SELECT apntoken,deviceid,created
FROM `distribution_mobiletokens` as dm
WHERE userid='20'
and not exists (
select 1
from `distribution_mobiletokens`
where userid = '20'
and deviceid = dm.deviceid
and created > dm.created
)
What this query does is selects all mobiletokens where the user id is equal to 20 and the deviceid is the same but chooses the newest apntoken for the device.
My database looks like below.
For more information on this query, I got this answer from another question I asked here( How to group by in SQL by largest date (Order By a Group By) )
Things I've Tried
$mobiletokens = $em->createQueryBuilder()
->select('u.id,company.id as companyid,user.id as userid,u.apntoken')
->from('AppBundle:MobileTokens', 'u')
->leftJoin('u.companyId', 'company')
->leftJoin('u.userId', 'user')
->where('u.status = 1 and user.id = :userid')
->setParameter('userid',(int)$jsondata['userid'])
->groupby('u.apntoken')
->getQuery()
->getResult();
//@JA - Get the list of all the apn tokens we need to send the message to.
foreach($mobiletokens as $tokenobject){
$deviceTokens[] = $tokenobject["apntoken"];
echo $tokenobject["apntoken"]."\n";
}
die();
This gives me the incorrect response of
63416A61F2FD47CC7B579CAEACB002CB00FACC3786A8991F329BB41B1208C4BA

Any help here is appreciated!
Other Information
Data with SELECT * FROM
Data after using the SQL I provided up top.
I did this for now as a temporary fix, not sure if this is best answer though.
$em = $this->em;
$connection = $em->getConnection();
$statement = $connection->prepare("
SELECT apntoken,deviceid,created
FROM `distribution_mobiletokens` as dm
WHERE userid=:userid
and not exists (
select 1
from `distribution_mobiletokens`
where userid = :userid
and deviceid = dm.deviceid
and created > dm.created
)");
$statement->bindValue('userid', $jsondata['userid']);
$statement->execute();
$mobiletokens = $statement->fetchAll();
//@JA - Get the list of all the apn tokens we need to send the message to.
foreach($mobiletokens as $tokenobject){
$deviceTokens[] = $tokenobject["apntoken"];
echo $tokenobject["apntoken"]."\n";
}
You could use a subselect created with the querybuilder as example:
public function selectNewAppToken($userId)
{
// get an ExpressionBuilder instance, so that you
$expr = $this->_em->getExpressionBuilder();
// create a subquery in order to take all address records for a specified user id
$sub = $this->_em->createQueryBuilder()
->select('a')
->from('AppBundle:MobileTokens', 'a')
->where('a.user = dm.id')
->andWhere('a.deviceid = dm.deviceid')
->andWhere($expr->gte('a.created','dm.created'));
$qb = $this->_em->createQueryBuilder()
->select('dm')
->from('AppBundle:MobileTokens', 'dm')
->where($expr->not($expr->exists($sub->getDQL())))
->andWhere('dm.user = :user_id')
->setParameter('user_id', $userId);
return $qb->getQuery()->getResult();
