Question

我想计算本周的记录。但我不知道我该怎么做。

这是我的问题：

$totalSearchesByUsersWeek = $em->createQueryBuilder()
    ->select('count(SearchHistory.id) AS totalSearchesByUsers')
    ->from('DRPAdminBundle:Log',  'SearchHistory')
    ->where('SearchHistory.last_updated like :last_updated')
    ->setParameter('last_updated',$week.'%')     
        ->getQuery()
        ->getArrayResult();

请帮忙

Answer 1

您可以将COUNT()与2个getSingleScalarResult个对象以及您对本周开始和结束的定义结合使用。使用$start = new \DateTime(); // This will depend on which day you decide the week starts if ('Monday' !== $start->format('l')) { // if week starts on Sunday you would just use (int) $start->format('w') $start->modify(sprintf('- %d days', (int) $start->format('w') - 1)); } // clone the start date and add 6 days to get the end date $end = clone($start); $end->modify('+ 6 days'); // set the times to midnight for start and 1 second before midnight for finish $start->setTime(0, 0, 0); $end->setTime(23, 59, 59); // for the date 2015-07-16 (today) this would result in // start = 2015-07-13 00:00:00 (Monday) // end = 2015-07-19 23:59:59 (Sunday) $queryBuilder = $em->createQueryBuilder(); return $queryBuilder ->select('COUNT(o.id)') ->from('DRPAdminBundle:Log', 'o') ->where($queryBuilder->expr()->between('o.last_updated', ':start', ':end')) ->setParameter('start', $start) ->setParameter('end', $end) ->getQuery() ->getSingleScalarResult();和$queryBuilder = $em->createQueryBuilder(); return $queryBuilder ->select('COUNT(o.id)') ->from('DRPAdminBundle:Log', 'o') ->where($queryBuilder->expr()->gte('o.last_updated', ':start')) ->setParameter('start', new \DateTime('- 7 days')) ->getQuery() ->getSingleScalarResult();，您只需获得单个整数计数即可。

presentModalViewController

同时

如果您只想过去7天就可以使用..

CustomModalViewController *modalVC =[[CustomModalViewController alloc]init]; [self presentModalViewController:modalVC animated:YES];

Answer 2

将getArrayResult()替换为getSingleScalarResult()，您将很高兴

编辑以回答您的评论：

$totalSearchesByUsersWeek = $em->createQueryBuilder()
->select('SearchHistory.id AS totalSearchesByUsers')
->from('DRPAdminBundle:Log',  'SearchHistory')
->where('SearchHistory.last_updated like :last_updated')
->setParameter('last_updated',$week.'%')
->getQuery();

 $totalSearchesByUsersWeek->->getArrayResult(); //this will get you the array of id

和

 $totalSearchesByUsersWeek = $em->createQueryBuilder()
->select('count(SearchHistory.id) AS totalSearchesByUsers')
->from('DRPAdminBundle:Log',  'SearchHistory')
->where('SearchHistory.last_updated like :last_updated')
->setParameter('last_updated',$week.'%')
->getQuery();
 $totalSearchesByUsersWeek->->getSingleScalarResult(); //this will get you the COUNT of id

Edit2：用这个

替换你的where子句

->where('SearchHistory.last_updated BETWEEN :monday AND :sunday')
->setParameter('monday', '2014-7-13')
->setParameter('sunday', '2014-7-19');  //or adjust date format accordingly
