Question

我正在尝试使用Laravel查询生成器运行此查询。 我认为查询是正确的，因为当我在MySQL Workbench中运行查询时，查询将执行并得到预期的结果。我知道我们可以使用laravel查询生成器编写原始查询，但它对SQL开放注入漏洞。因此，我正在尝试不使用原始查询。

这是查询

audio/mp3

我已经将每个表都设为模型，并在像这样的控制器中使用。由于表名与命名约定不同。我在每个模型中都添加了SELECT invoice.InvNo,customer.RouteCode,customer.CustomerCode,rootplan_product.RouteplanCode,invoice.Status FROM rootplan_product INNER JOIN customer ON customer.RouteCode = rootplan_product.RouteCode AND customer.CustomerCode = rootplan_product.customercode INNER JOIN invoice ON invoice.CustomerCode = customer.CustomerCode WHERE rootplan_product.RouteCode='MO-A' AND invoice.Status IN ('PENDING','ACTIVE') ORDER BY invoice.Status desc。

protected $table = 'correct_table_name';

这是控制器功能

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use \App\Route;
use \App\Customer;
use \App\Invoice;
use \App\Rootplan_Product;

在控制台中，我收到此错误

“ SQLSTATE [42S22]：找不到列：1054未知”在“ on子句”中（SQL：选择public function retrieveRouteCodeData(Request $request){ try { $RouteCode = $request->RouteCode; $retrievedData = DB::table('rootplan_product') ->join('customer', function($join){ $join->on('customer.RouteCode', '=', 'rootplan_product.RouteCode'); $join->on(DB::raw('(customer.CustomerCode = rootplan_product.CustomerCode)')); }) ->join('invoice', 'invoice.CustomerCode', '=', 'customer.CustomerCode') ->select('invoice.InvNo', 'customer.RouteCode', 'customer.CustomerCode', 'rootplan_product.RouteplanCode', 'invoice.Status') ->where('rootplan_product.RouteCode', $RouteCode) ->orderBy('invoice.Status','desc') ->get(); return response()->json(['msg'=>'Updated Successfully', 'result'=>$retrievedData, 'success'=>true]); } catch (\Exception $e) { return response()->json(['msg'=>$e->getMessage()]); } }。invoice，InvNo。customer ，RouteCode。customer，CustomerCode。rootplan_product，RouteplanCode。invoice来自Status内部联接rootplan_product customer。customer = RouteCode。rootplan_product和{customer.CustomerCode = rootplan_product.CustomerCode）=``RouteCode上的内部联接invoice。 invoice = CustomerCode。customer，其中CustomerCode。rootplan_product = MO-A订单，RouteCode。invoice desc）“ < / p>

我了解该查询很复杂，我们将不胜感激！

问题出在DB :: raw语句。请使用以下内容：

DB::table('rootplan_product')->join('customer', function ($join) {
    $join->on('customer.RouteCode', '=', 'rootplan_product.RouteCode');
    $join->on('customer.CustomerCode', 'rootplan_product.CustomerCode');
})->join('invoice', 'invoice.CustomerCode', '=', 'customer.CustomerCode')
    ->select('invoice.InvNo', 'customer.RouteCode', 'customer.CustomerCode', 'rootplan_product.RouteplanCode', 'invoice.Status')
    ->where('rootplan_product.RouteCode', '123')
    ->whereIn('invoice.Status', ['PENDING','ACTIVE'])
    ->orderBy('invoice.Status', 'desc')
    ->get();

这将生成以下SQL：

SELECT `invoice`.`InvNo`,
       `customer`.`RouteCode`,
       `customer`.`CustomerCode`,
       `rootplan_product`.`RouteplanCode`,
       `invoice`.`Status`
FROM `test`
INNER JOIN `customer` ON `customer`.`RouteCode` = `rootplan_product`.`RouteCode`
AND `customer`.`CustomerCode` = `rootplan_product`.`CustomerCode`
INNER JOIN `invoice` ON `invoice`.`CustomerCode` = `customer`.`CustomerCode`
WHERE `rootplan_product`.`RouteCode` = ?
  AND `invoice`.`Status` IN (?, ?)
ORDER BY `invoice`.`Status` DESC

使用Laravel查询生成器进行复杂的MySQL内部联接查询
