Question

I have one column with different values depending on result.
I would like to return one row with fix columns.

The column output as follows:

Group | Item
--------------
  G1  | 1
  G1  | 2
  G2  | 3

I would like to output as:

Group | Item1 | Item2 | Item3
-----------------------------
  G1  |   1   |   2   | N/A
  G2  |   3   |  N/A  | N/A

Please Help..

Thanks in Advance…

Answer 1

Because every group may have three items maximum, I would use PIVOT operator:

DECLARE @Test TABLE
(
     RowID  INT IDENTITY(1,1) PRIMARY KEY
    ,[Group]VARCHAR(10) NOT NULL
    ,Item   INT NOT NULL
    ,UNIQUE ([Group], Item)
);  
INSERT  @Test   VALUES ('G1', 1);
INSERT  @Test   VALUES ('G1', 2);
INSERT  @Test   VALUES ('G2', 3);

WITH PivotSource
AS
(
    SELECT   t.[Group], t.Item
            ,ROW_NUMBER() OVER(PARTITION BY t.[Group] ORDER BY t.RowID) RowNumber
    FROM    @Test t

)
SELECT   pvt.[Group]
        ,Item1 = ISNULL( CONVERT(VARCHAR(11), pvt.[1]) , 'N/A')
        ,Item2 = ISNULL( CONVERT(VARCHAR(11), pvt.[2]) , 'N/A')
        ,Item3 = ISNULL( CONVERT(VARCHAR(11), pvt.[3]) , 'N/A')
FROM    PivotSource src
PIVOT   ( MAX(src.Item) FOR src.RowNumber IN ([1], [2], [3]) ) pvt;

Results:

Group      Item1       Item2       Item3
---------- ----------- ----------- -----------
G1         1           2           N/A
G2         3           N/A         N/A
