--------------------------------------------------

结果

--------------------------------------------------
user_id                           amount_unit
--------------------------------------------------

我也想显示user_id。我尝试在控制器上仅显示amount_unit的总和，

$data = BankDeposit::with('user')->selectRaw('SUM(amount_unit) as au')
    ->groupBy('user_id')->get();

foreach ($data as $value) {
    echo $value;
}

Answer 1

您也应该将user_id传递给selectRaw()。

$data = BankDeposit::with('user')->selectRaw('SUM(amount_unit) as au, user_id')
           ->groupBy('user_id')->get();
