Solution 3

Here it is :
(I supposed that your table name is Rep)

SQL

with A as
(
SELECT [Name],[Month],[Number]
      ,row_number() over (partition by name , month order by name, month ) rno
  FROM Rep
)
select name , month, number, (
select sum(number) from a a2 where a2.rno<=a1.rno and a2.name=a1.name and a2.month=a1.month ) count
from a a1

Good Luck

Hello, try this query:

upd:

SQL

SELECT [xyz].[Name], [xyz].[Month], [xyz].[Number], sm.sub_total
  FROM [xyz]
  JOIN (SELECT [Name], [Month], [Number],
               ROW_NUMBER() OVER(ORDER BY [xyz].[Name], [xyz].[Month]) AS pos
          FROM [xyz] ) AS [xyzp]
    ON [xyz].[Name] = [xyzp].[Name] AND
       [xyz].[Month] = [xyzp].[Month] AND
       [xyz].[Number] = [xyzp].[Number]
 OUTER APPLY ( SELECT rn.[Name], [Month], SUM(rn.[Number]) AS sub_total
                 FROM ( SELECT ROW_NUMBER() OVER(ORDER BY [Name], [Month]) AS pos,
                               [Name], [Month], [Number]
                          FROM [xyz]
                       ) AS rn
                 WHERE rn.[Name] = [xyz].[Name] AND
                       rn.[Month] = [xyz].[Month] AND
                       rn.pos <= [xyzp].pos
                 GROUP BY rn.[Name], rn.[Month] ) AS sm

The query would be simplier if to use 'grouping sets' clause, but it only available in MS SQL 2008 or higher.
