Laravel Join 返回重复数据

Question

我试图获得前五名球员，我使用 join 根据 personId 获取每个球员的信息，但我的查询返回重复数据。我不知道为什么它会复制记录，任何帮助都会非常有用。谢谢

DB::table('person_competition_statistics as pcs')
                    ->where('pcs.competitionId', $competitionId)
                    ->where('pcs.teamId', $teamId)
                    ->orderBy('pcs.sStealsAverage', 'desc')
                    ->rightJoin('players as player', 'pcs.personId', '=',  'player.personId')
                    ->select(['pcs.personId', 'pcs.sStealsAverage', 'player.firstName', 'player.familyName', 'player.playingPosition', 'player.image_thumb'])
                    ->take(5)
                    ->get();

这是结果

#items: array:5 [?
      0 => {#444 ?
        +"personId": 29872
        +"sStealsAverage": 1.24
        +"firstName": "Rhys"
        +"familyName": ""
        +"playingPosition": ""
        +"image_thumb": ""
      }
      1 => {#438 ?
        +"personId": 29872
        +"sStealsAverage": 1.24
        +"firstName": "Rhys"
        +"familyName": ""
        +"playingPosition": ""
        +"image_thumb": ""
      }
      2 => {#439 ?
        +"personId": 29872
        +"sStealsAverage": 1.24
        +"firstName": "Rhys"
        +"familyName": ""
        +"playingPosition": "GRD"
        +"image_thumb": ""
      }
      3 => {#441 ?
        +"personId": 29872
        +"sStealsAverage": 1.24
        +"firstName": "Rhys"
        +"familyName": ""
        +"playingPosition": "GRD"
        +"image_thumb": ""
      }
      4 => {#435 ?
        +"personId": 29872
        +"sStealsAverage": 1.24
        +"firstName": "Rhys"
        +"familyName": ""
        +"playingPosition": "GRD"
        +"image_thumb": ""
      }

我使用unique返回唯一的 personId 和array_slice来获得前 5 名，下面是我的代码。

$spg = DB::table('person_competition_statistics as pcs')
                    ->where('pcs.competitionId', $competitionId)
                    ->where('pcs.teamId', $teamId)
                    ->orderBy('pcs.sStealsAverage', 'desc')
                    ->join('players as player', 'pcs.personId', '=',  'player.personId')
                    ->select(['pcs.personId', 'pcs.sStealsAverage', 'player.firstName', 'player.familyName', 'player.playingPosition', 'player.image_thumb'])
                    ->get();

$spg = $spg->unique('personId');
$spg = array_slice($spg->values()->all(), 0, 5, true);
