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 |
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
