Question

I need some help to build SQL Query. I have table having data like:

ID   Date         Value1 Value2 Code
1   12/01/2009     4       3.5     abc
2   12/02/2009     3       4.0     abc
3   11/03/2009     6       8.5     xyz
4   11/01/2009     2       5.5     abc
5   11/02/2009     4       6.0     xyz
6   12/03/2009     5       7.0     xyz

I need to show result something like…

        ---------
Code   | Data   |    November(Sum of Values in month)      December   Jan   Feb
abc    | Value1 |           2                                 7       0       0
       | Value2 |           5                                 7       0       0
xyz    | Value1 |           10                                5       0       0
       | Value2 |           14                                7       0       0
       ----------

I need sum of value in each month as in above data in columns group by code.

Have a look at this solution, and let me know what you think.

You have to use both PIVOT and UNPIVOT in this instance to get the result you are looking for. Hope this helps.

DECLARE @Table TABLE(
        ID INT,
        Date DATETIME,
        Value1 INT,
        Value2 FLOAT,
        Code VARCHAR(10)
)

INSERT INTO @Table (ID,Date,Value1,Value2,Code) SELECT  1,'12/01/2009',4,3,'abc'
INSERT INTO @Table (ID,Date,Value1,Value2,Code) SELECT  2,'12/02/2009',3,4,'abc'
INSERT INTO @Table (ID,Date,Value1,Value2,Code) SELECT  3,'11/03/2009',6,8,'xyz'
INSERT INTO @Table (ID,Date,Value1,Value2,Code) SELECT  4,'11/01/2009',2,5,'abc'
INSERT INTO @Table (ID,Date,Value1,Value2,Code) SELECT  5,'11/02/2009',4,6,'xyz'
INSERT INTO @Table (ID,Date,Value1,Value2,Code) SELECT  6,'12/03/2009',5,7,'xyz'


;WITH UnPvt AS (
        SELECT  *
        FROM    (
                    SELECT  Code,
                            DATENAME(MM, Date) MonthNameVal,
                            SUM(Value1) Value1,
                            SUM(Value2) Value2
                    FROM    (
                                SELECT  Code,
                                        Date,
                                        CAST(Value1 AS FLOAT) Value1,
                                        Value2
                                FROM    @Table
                            ) v
                    GROUP BY    Code,
                                DATENAME(MM, Date)
                ) Sub
        UNPIVOT
                (
                    Vals FOR RowValues IN (Value1, Value2)
                ) AS UnPvt
)
SELECT  *
FROM    UnPvt
PIVOT   (
            SUM(Vals)
            FOR MonthNameVal IN ([January],[February],[March],[April],[May],[June],[July],[August],[September],[October],[November], [December])
        ) AS pvt
ORDER BY Code, RowValues
