sql使数据库中重复数据id雷同

sql使数据库中重复数据id相同
id         StartData              Comment3        Title
1          2014/06/20             test1                  title1
2          2014/06/20             test 2                 title2
3          2014/06/20             test 3                 title11
4          2014/06/21             test 4                 title


我需要的结果是:
newid         StartData              Comment3        Title
1          2014/06/20             test1                  title1
1          2014/06/20             test 2                 title2
1          2014/06/20             test 3                 title11
2          2014/06/21             test 4                 title

DECLARE @T TABLE

  StartData datetime,
  Comment3 varchar(10),
  Title varchar(10))
INSERT INTO @T

SELECT 2,'2014/06/20','test 2','title2' UNION ALL
SELECT 3,'2014/06/20','test 3','title11' UNION ALL
SELECT 4,'2014/06/21','test 4','title'


SELECT  DENSE_RANK()OVER(ORDER BY  StartData)AS [Newid],
        StartData,
        Comment3,
