如何在没有聚合函数的sql server中创建数据透视查询

我使用MS sql SERVER 2008和我有以下数据：

select * from account;

| PERIOD | ACCOUNT | VALUE |
----------------------------
|   2000 |   Asset |   205 |
|   2000 |  Equity |   365 |
|   2000 |  Profit |   524 |
|   2001 |   Asset |   142 |
|   2001 |  Equity |   214 |
|   2001 |  Profit |   421 |
|   2002 |   Asset |   421 |
|   2002 |  Equity |   163 |
|   2002 |  Profit |   325 |

我想让他们成为这样：

| ACCOUNT | 2000 | 2001 | 2002 |
--------------------------------
|   Asset |  205 |  142 |  421 |
|  Equity |  365 |  214 |  163 |
|  Profit |  524 |  421 |  325 |

我试图查询使用枢轴查询，但值必须使用聚合函数，结果是不适当的。我该怎么办？

SELECT *
FROM
(
SELECT [Period],[Account],[Value]
FROM TableName
) AS source
PIVOT
(
    MAX([Value])
    FOR [Period] IN ([2000],[2001],[2002])
) as pvt

其他方式，

SELECT ACCOUNT,MAX(CASE WHEN Period = '2000' THEN Value ELSE NULL END) [2000],MAX(CASE WHEN Period = '2001' THEN Value ELSE NULL END) [2001],MAX(CASE WHEN Period = '2002' THEN Value ELSE NULL END) [2002]
FROM tableName
GROUP BY Account
