取得与该列的SQL Server 2008

Question

我想要做上述SQL Server 2008中的任何想法的MAX值整排？

Answer 1

是否这样？

设置：

declare @MyTable table(Year int, Month int, Day int, Total int) 

insert @MyTable 
values 
    (2005, 9, 23, 12), 
    (2005, 9, 26, 5), 
    (2005, 9, 24, 1), 
    (2005, 9, 15, 28), 
    (2005, 9, 21, 1), 
    (2005, 9, 13, 1), 
    (2005, 10, 31, 5), 
    (2005, 11, 18, 115), 
    (2005, 11, 20, 1), 
    (2005, 11, 11, 1), 
    (2005, 11, 19, 1) 

查询：

;with cte 
as 
(
    select *, 
     row_number() over(partition by Year, Month order by Total desc) RowNumber 
    from @MyTable 
) 
select Year, Month, Day, Total 
from cte 
where RowNumber = 1 

输出：

Year  Month  Day   Total 
----------- ----------- ----------- ----------- 
2005  9   15   28 
2005  10   31   5 
2005  11   18   115
