Laravel concat不工作

I have an issue on Laravel CONCAT it doesn't concatenate DB fields. When I checked the returned data it has no fullName

public function getAllPlayers()
{
    $data = Player::select(DB::raw('CONCAT(familyName," ",firstName) AS fullName'))
        ->orderBy('familyName', 'asc')
        ->join('teams', 'players.primaryClubId', '=', 'teams.clubId')
        ->select(['players.*', 'teams.teamName', 'teams.teamNickname', 'teams.teamCode'])
        ->get()
        ->unique() //remove duplicates
        ->groupBy(function($item, $key) { //group familyName that starts in same letter
            return substr($item['familyName'], 0, 1);
        })
        ->map(function ($subCollection) {
            return $subCollection->chunk(4); // put your group size
        });

    return $data;
}

    You are overriding select with another select. To add multiple select you need to use addSelect method.

    public function getAllPlayers()
    {
        $data = Player::select(DB::raw('CONCAT(familyName," ",firstName) AS fullName'))
            ->orderBy('familyName', 'asc')
            ->join('teams', 'players.primaryClubId', '=', 'teams.clubId')
            ->addSelect(['players.*', 'teams.teamName', 'teams.teamNickname', 'teams.teamCode'])
            ->get()
            ->unique() //remove duplicates
            ->groupBy(function($item, $key) { //group familyName that starts in same letter
                return substr($item['familyName'], 0, 1);
            })
            ->map(function ($subCollection) {
                return $subCollection->chunk(4); // put your group size
            });
    
        return $data;
    }
