Question

我想问一下如何从SQL Server DateTime查询中的Select列获取MIN DatePart。

这是我的疑问：

SELECT  
   MIN(CAST(DATEPART(DD, DateCreated) AS NVARCHAR) + 
   N'/' +
   CAST(DATEPART(MM, DateCreated) AS NVARCHAR) + 
   N'/' +
   CAST(DATEPART(YYYY, DateCreated) AS NVARCHAR)) AS DateFrom
FROM    
   [User]

结果应为04/04.2013，但现在结果为01/04/2014

请帮忙......
