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

这是我的查询：

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]

结果应该是04/04.2013，但现在，结果是01/04/2014

请帮忙 ....
