如何在此查询结果中添加ROW编号？

SELECT DISTINCT
  VehicleSpecs.SubmittedById,
  COUNT(VehicleSpecs.SubmittedById) AS NumCars,
  aspnet_Users.UserName
FROM
  VehicleSpecs
  INNER JOIN aspnet_Users ON VehicleSpecs.SubmittedById = aspnet_Users.UserId
WHERE
  (LEN(VehicleSpecs.SubmittedById) > 0)
GROUP BY
  VehicleSpecs.SubmittedById,
  aspnet_Users.UserName
ORDER BY
  NumCars DESC
