$goods=DB::select('SELECT COUNT(gn.rfid) as num,pro.* FROM goods_nexus
as gn RIGHT JOIN (SELECT g.* ,gc.class_name FROM goods as
g LEFT JOIN goods_class as gc ON g.class_id = gc.id)as pro

dd($goods);
下面是搜索条件的拼接：
public function index(Request $request){ $name=$request->input('name');
$where = ' WHERE 1'; if ($name){
$where = ' WHERE name like ' ."'%$name%'";
}
$goods=DB::select('SELECT COUNT(gn.rfid) as nums,pro.* FROM goods_nexus as gn
RIGHT JOIN (SELECT g.* ,gc.class_name
FROM goods as g
LEFT JOIN goods_class as gc
ON g.class_id = gc.id)as pro
ON pro.id = gn.goods_id '.$where.'
GROUP BY pro.id ASC'
);
return view('index') ->with('goods',$goods); }
