WITH T AS
(   SELECT Sno, Water, Milk
    FROM (VALUES (1, 50, 100), (2, 22, 120), (3, 11, 142)) t (Sno, Water, Milk)
)
SELECT  Sno = ROW_NUMBER() OVER(ORDER BY SUM(Upvt.Qnty)),
        upvt.Type,
        Qnty = SUM(Upvt.Qnty)
FROM    T
       UNPIVOT
        (   Qnty
            FOR Type IN ([Water], [Milk])
        ) upvt
GROUP BY upvt.Type
ORDER BY Qnty;

Hi,

It works OK on my machine. Maybe you accidentally marked the keyboard 'VALUES' before execution?

~~SQL Server 2008 does not support this kind of statement.~~
[EDIT]
Above statement is not true. Please see Andrius's comment to my answer.
Thank you, Andrius ;)

You can achieve that in 2 ways:
1) using temporary table (variable type table)

SQL

DECLARE @products TABLE(Sno INT, Water INT, Milk INT)

INSERT INTO @products
VALUES (1, 50, 100), (2, 22, 120), (3, 11, 142)


SELECT ROW_NUMBER() OVER(ORDER BY SUM(Qnty)) AS RowNo, Product, SUM(Qnty) AS Qnty
FROM (
    SELECT Product, Qnty
    FROM (
        SELECT *
        FROM @products
        ) AS pvt
    UNPIVOT (Qnty FOR Product IN ([Water],[Milk])) AS unpvt
) AS T
GROUP BY Product

or
2) using UNION ALL[^] statement

SQL

;WITH T AS
(
SELECT Sno, Water, Milk
  FROM (
      SELECT 1 AS Sno, 50 AS Water, 100 AS Milk
      UNION ALL
      SELECT 2, 22, 120
      UNION ALL
      SELECT 3, 11, 142
      ) t (Sno, Water, Milk))
SELECT  Sno = ROW_NUMBER() OVER(ORDER BY SUM(Upvt.Qnty)),
        upvt.Type,
        Qnty = SUM(Upvt.Qnty)
FROM    T
       UNPIVOT
        (   Qnty
            FOR Type IN ([Water], [Milk])
        ) upvt
GROUP BY upvt.Type
ORDER BY Qnty;
