Laravel如何return整条数据的最高值

Question

我怎样才能 return 整个项目数据，我已经使用 max 来获取最高值，但它只有 return 的值该字段不是整个项目

public static function getTeamLeaders($competitionId, $teamId) {
        if($teamId){
            $ppg = self::where('competitionId', $competitionId)
                    ->where('teamId', $teamId)
                    ->get()
                    ->max('Points');

            $apg = self::where('competitionId', $competitionId)
                    ->where('teamId', $teamId)
                    ->get()
                    ->max('Assists');

            $fgpg = self::where('competitionId', $competitionId)
                    ->where('teamId', $teamId)
                    ->get()
                    ->max('FieldGoals');

            $data = ['ppg' => $ppg, 'apg' => $apg, 'fgpg' => $fgpg];
            return $data;
        }
    }

结果：

array:3 [▼
  "ppg" => 15.18
  "apg" => 3.76
  "fgpg" => 12.04
]

Answer 1

您可以使用 orderBy 对您想要最大值的字段进行排序，然后 select 第一个结果。

docs: https://laravel.com/docs/5.4/queries#ordering-grouping-limit-and-offset https://laravel.com/docs/5.4/queries#retrieving-results

$ppg = self::where('competitionId', $competitionId)
                ->where('teamId', $teamId)
                ->orderBy('Points', 'desc')
                ->first();

Answer 2

而不是使用 max 使用 orderBy

self::where('competitionId', $competitionId)
                    ->where('teamId', $teamId)
                    ->orderBy('Points', 'desc')
                    ->first();

我认为您应该像这样更新您的代码：

public static function getTeamLeaders($competitionId, $teamId) {
        if($teamId){
            $ppg = self::where('competitionId', $competitionId)
                    ->whereRaw('Points = (select max(`Points`) from table_name)')
                    ->where('teamId', $teamId)
                    ->get();


            $apg = self::where('competitionId', $competitionId)
                    ->whereRaw('Assists = (select max(`Assists`) from table_name)')
                    ->where('teamId', $teamId)
                    ->get());

            $fgpg = self::where('competitionId', $competitionId)
                    ->whereRaw('FieldGoals = (select max(`FieldGoals`) from table_name)')
                    ->where('teamId', $teamId)
                    ->get();

            $data = ['ppg' => $ppg, 'apg' => $apg, 'fgpg' => $fgpg];
            return $data;
        }
    }

希望这对你有用！

Answer 4

仅将'max'改为'orderBy'。

$something= self::where('competitionId', $competitionId)
            ->where('teamId', $teamId)
            ->orderBy('Points', 'desc')
            ->first();
