Rows to columns SQL query

I am writing a query that will be used in a .NET application, therefore I would like the SQL Server 2008 o do much of the processing for me instead of the client PC that the application will run on.

I am trying to get data from some tables I joined together.

Here is an example:

SELECT SUBSTRING(CAST(CAST(HCPD.SeferCikisZamani AS TIME) AS VARCHAR), 1, 5) AS Kalkis, SUBSTRING(CAST(CAST(HCPD.DonusZamani AS TIME) AS VARCHAR), 1, 5) AS Donus, V.AracPlaka
FROM HAT_CALISMA_PLANI HCP WITH(NOLOCK)
INNER JOIN HAT_CALISMA_PLANI_DETAY HCPD WITH(NOLOCK) ON HCPD.HatCalismaPlaniKey = HCP.HatCalismaPlaniKey
INNER JOIN VALIDATOR V WITH(NOLOCK) ON V.ValidatorKey = HCPD.ValidatorKey
WHERE HCP.HatKey = 2 AND CAST(HCPD.SeferCikisZamani AS DATE) = '2012-09-25'
ORDER BY Kalkis

This query returns this result:

Kalkis  Donus   AracPlaka
-------------------------
01:51   02:01   07 ABY 04
02:02   02:12   07 AB 978
02:21   02:31   07 ABY 04
02:32   02:42   07 AB 978
03:01   03:11   07 ABY 04
03:02   03:12   07 AB 978
03:31   03:41   07 ABY 04
03:42   03:52   07 AB 978
04:01   04:11   07 ABY 04

However, In my report they are supposed to look like this,

        07 ABY 04   07 AB 978
Kalkis  06:15       06:30
Donus   07:45       08:00
Kalkis  08:00       08:10
Donus   09:30       09:40
Kalkis  10:00       10:15
Donus   11:30       11:45
Kalkis  12:30       12:45
Donus   14:00       14:15

By the way, these are like bus schedules. Anyone know a good way to achieve this?

It would be easier to see the data before you queried it, but if you want to use your existing query, you can do the following:

select *
from
(
  select AracPlaka, val, col,
     row_number() over(partition by AracPlaka order by VAL, col) rn
  from
  (
    SELECT SUBSTRING(CAST(CAST(HCPD.SeferCikisZamani AS TIME) AS VARCHAR), 1, 5) AS Kalkis, 
      SUBSTRING(CAST(CAST(HCPD.DonusZamani AS TIME) AS VARCHAR), 1, 5) AS Donus, 
      V.AracPlaka
    FROM HAT_CALISMA_PLANI HCP WITH(NOLOCK)
    INNER JOIN HAT_CALISMA_PLANI_DETAY HCPD WITH(NOLOCK) 
      ON HCPD.HatCalismaPlaniKey = HCP.HatCalismaPlaniKey
    INNER JOIN VALIDATOR V WITH(NOLOCK) 
      ON V.ValidatorKey = HCPD.ValidatorKey
    WHERE HCP.HatKey = 2 
      AND CAST(HCPD.SeferCikisZamani AS DATE) = '2012-09-25'
   -- ORDER BY Kalkis
  ) x
  unpivot
  (
    val
    for col in(Kalkis, Donus)
  ) u
) x1
pivot
(
  max(val)
  for AracPlaka In([07 ABY 04], [07 AB 978])
) p

Since you are attempting to PIVOT two columns, the easiest way is to UNPIVOT the Kalkis and the Donus columns first, then apply the PIVOT to the data.

Here is a SQL Fiddle with Demo (excludes your original query)
