WHERE子句与Laravel中的另一个表的关系

Question

我的Laravel应用程序中有几个表，一个叫发货，另一个叫payment_distributions。

在我的货物中，我有名为pro_number和balance的列。

在我的payments_distributions中，我有一个名为shipment_id和amount的列。

现在我有一个控制器，里面有这部分代码：

}elseif($_GET['paymentStatus']=="Unpaid"){
    if(empty($_GET['pro_number'])){
            $shipment = NULL;
        }else{
        $shipment = $_GET['pro_number'];
        }

        if($_GET['startDate']){
            $startDate = $_GET['startDate'];
        }
        if($_GET['endDate']){
            $endDate = $_GET['endDate'];
        }
                $start = $_GET['startDate'];
                $end = $_GET['endDate'];
                $status = $_GET['paymentStatus'];
    $date = \Carbon\Carbon::today()->subDays(0);

    $shipments = Shipment::sortable()
    ->where([
        ['due_date','<=',date($date)],
        ['pro_number', 'LIKE', '%' . $shipment . '%'],
        ['balance','>','SELECT SUM(payments_distributions.amount) FROM payments_distributions WHERE payments_distributions.shipment_id = pro_number'],
    ])
    ->whereBetween('date', [$startDate, $endDate])
    ->whereNotIn('shipment_billing_status', [2,3])
    ->paginate(25);
    return view('shipments.accounts', compact('shipments','start','end','status'));

}

现在我的问题出现了，如果我将它放入MYSQL中，以下代码可以工作：

SELECT SUM(payments_distributions.amount) FROM payments_distributions WHERE payments_distributions.shipment_id = 214050

将返回SUM（payments_distributions.amount）：300.00

所以，如果你去我的代码中的行，这是唯一不起作用的东西，所以如果可以的话，这行代码是否适合所有人？我想说的是，货运行中的余额字段必须大于payment_distributions表中amount字段的总和，其中payment_distributions表中的shipment_id字段等于货件表中的pro_number字段。

 ['balance','>','SELECT SUM(payments_distributions.amount) FROM payments_distributions WHERE payments_distributions.shipment_id = pro_number'],
    ]

更新（整个功能）

public function accountsQuery(){


if(($_GET['paymentStatus'] == "No Settle") or ($_GET['paymentStatus'] == "No Charge")){
            if($_GET['paymentStatus'] == "No Settle"){
                $status = 3;
            }elseif($_GET['paymentStatus'] == "No Charge"){
                $status = 2;
            }
                if(empty($_GET['pro_number'])){
                $shipment = NULL;
                }else{
                $shipment = $_GET['pro_number'];
                }

                if($_GET['startDate']){
                    $startDate = $_GET['startDate'];
                }
                if($_GET['endDate']){

                        $start = $_GET['startDate'];
                        $end = $_GET['endDate'];
                        $status = $_GET['paymentStatus'];
                        $shipments = \App\Shipment::sortable()->where([ 
                            ['pro_number', 'LIKE', '%' . $shipment . '%'],
                            ['shipment_billing_status', 'LIKE', '%' . $status . '%'],
                        ])
                            ->whereBetween('date', [$startDate, $endDate])
                            ->paginate(25);
                return view('shipments.accounts', compact('shipments','start','end','status'));

}elseif($_GET['paymentStatus']=="Billed"){
    if(empty($_GET['pro_number'])){
            $shipment = NULL;
        }else{
        $shipment = $_GET['pro_number'];
        }

        if($_GET['startDate']){

        }
                $start = $_GET['startDate'];
                $end = $_GET['endDate'];
                $status = $_GET['paymentStatus'];
    $date = \Carbon\Carbon::today()->subDays(30);
    //AND TO MENTION WHERE SUM OF PAYMENTS TO THIS SHIPMENT < BALANCE DUE
    $shipments = Shipment::sortable()
    ->where([
        ['date','>=', date($date)],
        ['pro_number', 'LIKE', '%' . $shipment . '%'],
    ])
    ->whereBetween('date', [$startDate, $endDate])
    ->paginate(25);
    return view('shipments.accounts', compact('shipments','start','end','status'));

}elseif($_GET['paymentStatus']=="Unpaid"){
    if(empty($_GET['pro_number'])){
            $shipment = NULL;
        }else{
        $shipment = $_GET['pro_number'];
        }

        if($_GET['startDate']){
            $startDate = $_GET['startDate'];
        }
        if($_GET['endDate']){
            $endDate = $_GET['endDate'];

    ->whereBetween('date', [$startDate, $endDate])

Answer 1

您应该能够将该子查询用作whereRaw表达式的一部分：

->where([
    ['due_date','<=',date($date)],
    ['pro_number', 'LIKE', '%' . $shipment . '%']])
->whereRaw('balance > SELECT SUM(p.amount) FROM payments_distributions p WHERE p.shipment_id = pro_number')
->whereBetween('date', [$startDate, $endDate])
...

但是，我怀疑我们可能会重写您的查询以废除WHERE子句中的相关子查询。
