ขอปรีกษาเรื่องการอัพเดตข้อมูลใน dababase หน่อยคับ

function editPayment($payment_id)
		{
			$obj = new mainClass();
			$con = $obj->connectDB();

			$sql = "SELECT * FROM affiated_sale_for_banners WHERE order_id='$payment_id'";
			$result = $obj->queryData($sql);
			$row = $result->num_rows;

			if($row > 0)
			{
				
				$sql = "UPDATE orders, affiated_sale_for_banners SET orders.payment_status = 2 affiated_sale_for_banners.payment_status = 2 WHERE orders.order_id='$payment_id' AND affiated_sale_for_banners.order_id='$payment_id'";
				$result = $obj->queryData($sql);
			}
			else
			{
				$sql = "UPDATE orders SET payment_status = 2 WHERE order_id='$payment_id'";
				$result = $obj->queryData($sql);
			}
