Sql server 按查询分组无法正常工作sql server 2005

我应该得到这样的结果，我试过分组，但没有任何效果像我在这里需要的那样

Exp                      Reason    CreditAccounts   Points  
2012-01-30 02:11:58.830  Inactive   1               5           
2012-01-31 02:11:58.827  Inactive   1               5   
2012-02-01 02:12:02.130  Inactive   2               10  
2012-02-03 02:11:58.820  Inactive   4               20  
2012-02-03 02:12:02.120  Inactive   2               10  
2012-02-04 02:12:02.113  Inactive   4               20

这方面的任何解决方案都会很好 谢谢

普林斯看起来你想按日期分组？您忽略了包含关于表定义或需求的任何附加信息，但可能需要类似的内容

Exp                      Reason    CreditAccounts   Points  
2012-01-30 02:11:58.830  Inactive   1               5           
2012-01-31 02:11:58.827  Inactive   1               5   
2012-02-01 02:12:02.130  Inactive   2               10  
2012-02-03 02:11:58.820  Inactive   6               30  
2012-02-04 02:12:02.113  Inactive   4               20

谢谢，很好，马丁·史密斯

SELECT MIN(Exp) AS Exp,
       Reason,
       SUM(CreditAccounts) AS CreditAccounts,
       SUM(Points) AS Points
FROM SomeTable
GROUP BY  Reason,  DATEDIFF(DAY, 0, Exp)
