selectRaw 中的原始子查询

Question

 BowlerMaster::selectRaw(" 
    tour_id, bowler_id, bowler_name, ball_team,
    SUM(balls) AS balls,
    SUM(overs) AS overs,                
    DB::raw('SELECT runs, wicket FROM bowler_master WHERE tour_id = ".$request->tour_id." AND bowler_id = ".$request->player_id." ORDER BY wicket DESC, runs LIMIT 1 AS bbi')
        ")
->where($where_array)
->groupby(['tour_id','bowler_id'])
->get()->first();

在上面的 Eloquent 查询中，我想使用原始查询或任何其他方式来获取原始查询的结果以获取 bbi 的值，但我收到以下错误：

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '::raw('SELECT match_id, runs, wicket FROM bowler_master WHERE tour_id = 1 AND bo' at line 25.

我正在编写此查询以生成以下输出，

{
    "status": 200,
    "message": "Success",
    "bowler": {
        "tour_id": 1,
        "bowler_id": 21,
        "bowler_name": "Kaushal Chauhan",
        "ball_team": null,
        "balls": "29",
        "overs": 4.5,
        "bbi": 9/3,
    }
}

Uptil 结束计算，一切正常。我不知道如何获得 "bbi" key:value 注意：查询的结果会被压入response数组，并转换成json得到如上所示的输出。

请指导。

试试这个

BowlerMaster::selectRaw("tour_id, bowler_id, bowler_name, ball_team, SUM(balls) AS balls,SUM(overs) AS overs")
        ->selectSub("  
                   SELECT runs 
                   FROM bowler_master 
                   WHERE tour_id = ".$request->tour_id." 
                   AND bowler_id = ".$request->player_id." 
                   ORDER BY wicket DESC, runs LIMIT 1
        ","runs")
        ->selectSub("  
                    SELECT wicket 
                    FROM bowler_master 
                    WHERE tour_id = ".$request->tour_id." 
                    AND bowler_id = ".$request->player_id." 
                    ORDER BY wicket DESC, runs LIMIT 1
           ","wicket")
        ->where($where_array)
        ->groupby(['tour_id','bowler_id'])
        ->get()->first();

在laravel中编写select子查询的规则如下：

DB::table('tablename')
    ->select('column name','..')
    ->selectSub("Your full query","alias name")
    ->get()

selectRaw 中的原始子查询
