按日期过滤现有查询

Question

这尚未得到功能性答案。

我已经综合了几种方法来获得我经常玩的游戏的一些有趣统计数据。

下面的方法将计算所有玩过的游戏的总数，将一个玩家与该玩家列表匹配，然后显示总赢/亏损/平局的总和。

这很棒，而且功能齐全。

但是，由于受欢迎的需求，我被要求调整查询以现在考虑游戏进行的日期。我想将其过滤到求和的最后30天。我怎样才能做到这一点？

我想在花时间重写整个内容之前先四处询问。最好，所有内容保持不变，只是按日期过滤。

数据库的日期密钥checkSumID是UNIX时间戳。

private function topPlayers() {

        $topPlayersList = array();

        $playersList = DB::table('pickup_results')
            ->select(DB::raw("playerID"),
                DB::raw("COUNT(CASE WHEN gameResult = 'Win'  THEN 1 END) AS wins"),
                DB::raw("COUNT(CASE WHEN gameResult = 'Loss' THEN 1 END) AS loss"),
                DB::raw("COUNT(CASE WHEN gameResult = 'Tie' THEN 1 END) AS tie")
            )
            ->groupBy('playerID')
            ->orderBy('wins','DESC')
            ->get();

        $i = 0;

        foreach ($playersList as $playerListData) {

            if ($playerListData->wins + $playerListData->loss + $playerListData->tie >= 25) {

                $avgPick = $this->getPlayerAvgPickCount($playerListData->playerID);

                $playerRecordID = $playerListData->playerID;

                $playerNameLookup = Players::where([
                    'player_id' => $playerListData->playerID
                ])->first();

                $playerListData->playerID = $playerNameLookup->player_name;

                $topPlayersList[$i] = array(
                    'name' => $playerNameLookup->player_name,
                    'total' => +$playerListData->wins + +$playerListData->loss + +$playerListData->tie,
                    'wins' => +$playerListData->wins,
                    'loss' => +$playerListData->loss,
                    'tie' => +$playerListData->tie,
                    'percent' => +$playerListData->loss == 0 ? 0 : round(
                            (+$playerListData->wins / (+$playerListData->wins + +$playerListData->loss) * 100),
                            2
                        ) . ' %',
                    'avg_pick' => $avgPick[0]->average,
                    'player_id' => $playerRecordID
                );

                $i++;

            }

        }

        return $this->sortArray($topPlayersList,'percent','DESC');
    }

我写过一种方法，它做的事情类似，但更多的是基于一个人，但不确定如何在不进行完全重写的情况下将两者缝合在一起。

这是这种方法

private function getTotalGamesPlayed30DayWinLossTies() {

        //PickupResults::where('playerID', '=', $this->getPlayerID())->where('checkSumID', '=', Carbon::now()->subDays(30)->timestamp)->count()
        $results = PickupResults::get();

        //$results = PickupResults::where('playerID', '=', $this->getPlayerID())->get();

        $count = 0;
        $wins = 0;
        $loss = 0;
        $tie = 0;
        foreach ($results as $result) {

            if ($result->playerID === $this->playerID) {
                $timeStamp = $result->checkSumID;

                $converted = date('m/d/Y', $timeStamp / 1000);
                if (strtotime($converted) > strtotime('-30 days')) {
                    $count = $count + 1;
                    if ($result->gameResult === 'Win') {
                        $wins = $wins + 1;
                    }
                    if ($result->gameResult === 'Loss') {
                        $loss = $loss + 1;
                    }
                    if ($result->gameResult === 'Tie') {
                        $tie = $tie + 1;
                    }

                }
            }

        }

        return
            array(
                'total' => $count,
                'wins' => $wins,
                'loss' => $loss,
                'tie' => $tie,
                'percent' => $loss == 0 ? 0 : round(($wins / ( $wins + $loss) * 100 ),2) . ' %'
            );
    }

任何帮助将不胜感激。

使用Arun P的答案时

$playersList = DB::table('pickup_results')
    ->select(DB::raw("playerID"),
        DB::raw("COUNT(CASE WHEN gameResult = 'Win'  THEN 1 END) AS wins"),
        DB::raw("COUNT(CASE WHEN gameResult = 'Loss' THEN 1 END) AS loss"),
        DB::raw("COUNT(CASE WHEN gameResult = 'Tie' THEN 1 END) AS tie"))
    ->where('checksumID','<',$now)->where('checksumID','>',$thirty_days_ahead)
    ->groupBy('playerID')
    ->orderBy('wins', 'DESC')
    ->get();

它将返回0个结果。这是不正确的。我正在尝试收集玩家最近30天内玩过的所有游戏。没有更多，也没有更少。

您可以访问http://www.Krayvok.com/t1并查看统计信息页面以获取可用示例。

我正在尝试使用当前的排行榜，该排行榜显示所有玩家的总比赛次数。我想过滤掉它，以仅显示从今天起（过去30天）过去30天内玩过游戏的玩家。

我对您现有的查询做了一些更改，

$timestamp_from = date('Y-m-d', strtotime('-30 days'));

$playersList = DB::table('pickup_results')
    ->select(DB::raw("playerID"),
        DB::raw("COUNT(CASE WHEN gameResult = 'Win'  THEN 1 END) AS wins"),
        DB::raw("COUNT(CASE WHEN gameResult = 'Loss' THEN 1 END) AS loss"),
        DB::raw("COUNT(CASE WHEN gameResult = 'Tie' THEN 1 END) AS tie")
    )
    ->where(DB::raw("DATE((checkSumID/1000)) >= '{$timestamp_from}'"))
    ->groupBy('playerID')
    ->orderBy('wins','DESC')
    ->get();

在您的方法中，getTotalGamesPlayed30DayWinLossTies有一个除以 1000 的操作checkSumID，我已将其包含在查询中。的 where 子句checkSumID已更改为比较日期。
