按日期过滤现有查询

Question

这还没有用功能性的答案来回答。

我有一些方法，我将它们放在一起，以获得我经常玩的游戏的一些有趣的统计数据。

下面的方法将获取所有游戏的总数，将玩家与玩家列表匹配，然后显示总数的总和 wins/loss/ties。

这很棒，而且很实用。

但是，由于大众需求，我被要求调整查询以考虑游戏开始的日期。我想将其过滤到最后 30 天的总和。我该怎么做？

我想在花时间重写整个东西之前四处询问。最好，一切都保持不变，只是按日期过滤。

数据库的日期键是checkSumID它是一个 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');
    }

我写了一个方法，可以做类似的事情，但更多的是在一个人的基础上，但不确定如何在不完全重写的情况下将两者拼接在一起。

这是方法

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) . ' %'
            );
    }

如有任何帮助，我们将不胜感激。

当使用 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 return 0 个结果。这是不正确的；我试图收集玩家在过去 30 天内玩过的所有游戏。不多也不少。

您可以访问 http://www.Krayvok.com/t1 并查看统计页面以获取工作示例。

我正在尝试获取当前排行榜，该排行榜显示所有玩家玩过的游戏总数。我想对其进行过滤，以仅显示从今天开始的过去 30 天内（滚动 30 天）玩过游戏的玩家。

Answer 1

试试这个 from_unixtime() returns 来自 unix 时间戳的 date/datetime

$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("from_unixtime(checkSumID) > date_sub(now(), interval 30 day)"))
        ->groupBy('playerID')
        ->orderBy('wins','DESC')
        ->get();

Answer 2

试试这个，像这样更新您的查询

 $thirty_days_ahead = date('Y-m-d H:i:s', strtotime("-30 days"));
    $now = date('Y-m-d H:i:s', strtotime("0 days"));


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

Answer 3

试试这个 -

$playersList = DB::table('pickup_results')
        ->select(DB::raw("playerID"),
            DB::raw("COUNT(CASE WHEN gameResult = 'Win' AND checkSumID > '".now()->subDays(30)->toDateString()."' THEN 1 END) AS wins"),
            DB::raw("COUNT(CASE WHEN gameResult = 'Loss' AND checkSumID > '".now()->subDays(30)->toDateString()."' THEN 1 END) AS loss"),
            DB::raw("COUNT(CASE WHEN gameResult = 'Tie' AND checkSumID > '".now()->subDays(30)->toDateString()."' THEN 1 END) AS tie")
        )
        ->groupBy('playerID')
        ->orderBy('wins','DESC')
        ->get();

Laravel 创建 carbon date instance for now() as mentioned in its documentation. Chaining the above carbon methods (carbon docs) returns 30 天前的日期。

所有 SELECT 语句将转换为类似这样的内容（当当前日期为“2019-07-06”时）-

COUNT(CASE WHEN gameResult = 'Win' AND checkSumID > '2019-06-06' THEN 1 END) AS wins

这将计算在“2019-06-06”（过去 30 天内）之后创建的结果包括当前日期。

Answer 4

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 getTotalGamesPlayed30DayWinLossTies 中，checkSumID 被除以 1000，我已将其包含在查询中。 checkSumID 的 where 子句已更改为比较日期。

如果您需要任何帮助，请尝试发表评论。
