【问题描述】：
我的 Laravel 应用程序中有几个表，一个称为 shipping，另一个称为 payment_distributions。
在我的货件中，我有名为 pro_number 和 balance 的列。
在我的 payment_distributions 中，我有名为 shipping_id 和 amount 的列。
现在我有一个控制器，其中包含这部分代码：
}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, $endDate])
->whereNotIn('shipment_billing_status', [2,3])
->paginate(25);
return view('shipments.accounts', compact('shipments','start','end','status'));
}
现在我的问题出现了，如果我将以下代码放入 MYSQL 中，则它可以工作：
SELECT SUM(payments_distributions.amount) FROM payments_distributions WHERE payments_distributions.shipment_id = 214050
将返回 SUM(payments_distributions.amount): 300.00
所以，如果您转到我的代码中的行，这是唯一不起作用的东西，所以如果可以的话，这行代码对每个人来说都是正确的吗？我想说的是，发货行中的余额字段必须大于 payment_distributions 表中的 amount 字段之和，其中 payment_distributions 表中的 shipping_id 字段等于发货表中的 pro_number 字段。
['balance','>','SELECT SUM(payments_distributions.amount) FROM payments_distributions WHERE payments_distributions.shipment_id = pro_number'],
]
更新（整个函数）
public function accountsQuery(){
if(($_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']){
$endDate = $_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']){
$startDate = $_GET['startDate'];
}
if($_GET['endDate']){
$endDate = $_GET['endDate'];
}
$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'];
}
$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', '%' . $shipment . '%'],
])
->whereRaw('balance > SELECT SUM(p.amount) FROM payments_distributions p WHERE p.shipment_id = pro_number')
->whereBetween('date', [$startDate, $endDate])
->whereNotIn('shipment_billing_status', [2,3])
->paginate(25);
return view('shipments.accounts', compact('shipments','start','end','status'));
}
}
【问题讨论】：
-
尝试使用 DB::raw() 调用围绕内部 SELECT（与余额进行比较的地方）。您看到的问题是因为查询生成器将 balance 与包含 SQL 语句的字符串进行比较，而不是 SQL 语句的结果。
-
@Jason - 我已将所有内容更改回原来的内容，现在在我的 where([.... 部分我有以下内容：['balance', '>', DB::raw( 'SELECT IFNULL(SUM(p.amount),0) FROM payment_distributions p WHERE p.shipment_id = shipping.pro_number')], - 但我返回此错误
-
您的 SQL 语法有错误；检查与您的 MariaDB 服务器版本相对应的手册，以在第 1 行的 'SELECT IFNULL(SUM(p.amount),0) FROM payment_distributions p WHERE p.shipment_id' 附近使用正确的语法（SQL：select count(*) as从
shipments聚合，其中 (due_datepro_number LIKE %% 和balance> SELECT IFNULL(SUM(p.amount),0) FROM payment_distributions p WHERE p.shipment_id = shipping.pro_number) 和date在 1997-12-01 和 2017-12-26 之间和shipment_billing_status不在 (2, 3)) 中
