sql 相同列值统一编号、相同列值自动编号

select
　　ROW_NUMBER() over(order by t1.new_machineName) as N'自动编号',
　　DENSE_RANK() over(order BY t1.new_machineName) AS N'相同列值统一编号',
　　ROW_NUMBER() over(partition by t1.new_machineName Order by t1.new_machineName ASC,t1.statuscode asc,t1.new_stopdate desc) as N'相同列值自增编号',
　　t1.new_machineName,
　　t1.statuscode,
　　t1.new_stopdate,
　　t1.new_customercontractName
from new_contractmachine t1

结果如下图：
