我有两张表winners和check_winners。
id check_winner_id username win_number .... 1 1 xxx 1 2 2 xxx 1 3 3 yyy 1 4 4 yyy 1
id user_id chance_of_win.... 1 1 1 2 1 1 3 2 1 4 2 1 5 2 1 6 2 1 7 2 1 8 2 1
现在我想要join两个表，并希望将chance_of_win列和win_number列组加username。我尝试了一种方法，但它没有给出win_number之和的确切结果。我怎样才能做到这一点？
$winners = DB::table('winners')
->groupBy('winners.username')
->leftJoin('check_winners', 'winners.id', '=', 'check_winners.user_id')
->selectRaw('*, sum(check_winners.chance_of_win) as chance_sum, sum(winners.win_number) as win_sum')
dd($winners);
用这个我得到输出：
array:2 [▼
0 => {#241 ▼
+"id": 1
+"check_winner_id": 1
+"username": "xxx"
+"chance_sum": "2"
+"win_sum": "2"
}
1 => {#242 ▼
+"id": 2
+"check_winner_id": 2
+"username": "yyy"
+"chance_sum": "6"
+"win_sum": "6"
}
]
但win_sum 2 array <?php

require 'PHPMailer/src/PHPMailer.php';
require 'PHPMailer/src/Exception.php';
require 'PHPMailer/src/SMTP.php';

$mail->Body .= "<ul><li>" . $name . "</li>";

// $mail->Body = $body;
$mail->send();
}
catch (Exception $e) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
}
?>
。我哪里做错了？提前谢谢。

你应该试试这个：
$winners = DB::table('winners')
->leftJoin('check_winners', 'winners.id', '=', 'check_winners.user_id')
->selectRaw('*, sum(check_winners.chance_of_win) as chance_sum, sum(winners.win_number) as win_sum')
->groupBy('winners.username')
dd($winners);
更新回答
$winners = DB::table('winners')
->select('*', DB::raw("SUM(check_winners.chance_of_win) as chance_sum"), DB::raw("SUM(winners.win_number) as win_sum"))
->leftJoin('check_winners', 'winners.id', '=', 'check_winners.user_id')
->groupBy('winners.username')
