php - Laravel chunkbyid 用于连接

Question

当我在带有连接的查询生成器上使用 chunkById 时，我没有得到输出

 DB::table('cs')
 ->join('hw','hw.p1', '=', 'cs.awb')
 ->where('cs.dv','hw')
 ->chunkById(100, function ($hw_orders) use (&$hwCount) {
 foreach ($hw_orders as $hwd){
  Log::info('Number ' . $hwd->awb);
 });

我想知道如何通过连接对这些数据进行分块。 谢谢

尝试将额外的 param 作为列名称传递给 chunkById

DB::table('cs')
        ->join('hw','hw.p1', '=', 'cs.awb')
        ->where('cs.dv','hw')
        ->chunkById(100, function ($hw_orders) {
            foreach ($hw_orders as $hwd) {
                Log::info('Number ' . $hwd->awb);
            }
        },'cs.awb','p1');
