Хранимая процедура SQL, выводит строки в виде столбцов для сводки

Использование SQL 2005 Вот как выглядят мои результаты SQL 

UserID | Frame | Choice | Description | DateTime
------------------------------------------------
bcn005 | PL_P03| 1      | Rules-Based | 2011-10-24 14:14:26
bcn005 | PL_P04| 0      | VirtueBased | 2011-10-24 14:16:37
...
bmk172 | Prac_1| 0      | None        | 2011-10-25 12:45:38
...

Мой клиент хочет, чтобы результаты выглядели так 

UserID | Frame | Choice | Description | DateTime  | Frame | Choice | Description | DateTime 
-------------------------------------------------------------------------------------------
bcn005 | PL_P03| 1      | Rules-Based | 2011-10-..| PL_P04| 0      | VirtueBased | 2011-10-..
bmk172 | Prac_1| 0      | None        | 2011-10-..|

Где ответы всех участников находятся в одном ряду. В основном должен быть другой набор Frame / Choice Description / DateTime для каждой строки набора результатов.

Это результаты опроса, но это тип опроса, когда один участник мог вернуться и изменить свой ответ 5 раз. Таким образом, количество Frame / Choice Description / DateTime для каждого UserID будет разным.

Я знаю, что должен использовать хранимую процедуру (или, может быть, даже макрос Excel), но я совершенно новичок в обоих случаях. Любое руководство приветствуется. Вот мой SQL-запрос 

select UserID, locationName AS 'Frame', student_response AS 'Choice',
description, DateTime
from tblStudentResponses
WHERE GroupID in (18,20,21,36,37,38,39,40)
AND UserID in (SELECT UserID FROM tblStudentResponses WHERE
locationName = 'Character1Certificate')
AND DateTime > '2011-10-01'
AND type = 'choice'
order by UserID

Если SQL 2005 или ABove, вы можете попробовать pivot.

Если SQL 2000, используйте комбинацию Group By и Case. 

SELECT GC1,
       GC2,
       MAX(CASE WHEN CONDITION1 THEN Value1 ELSE Value2 END) AS DerivedColumn
FROM Table1
GROUP BY GC1, GC2

То, что вы хотите, это функциональность сводной таблицы SQL Server
