Question

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

我应该得到这样的结果，我尝试分组，但没有什么工作像我需要的方式

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  

对此的任何解决方案都会很棒 谢谢 王子

Answer 1

看起来你正试图按日期分组？您忽略了包含有关表定义或要求的任何其他信息，但可能需要类似

的内容

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