Sql server 更改SQL显示结果（按名称分组）

我的SQL查询可以显示以下结果：

Name   Project       Date
Peter    A           2014-12-11
Peter    C           2014-12-12
Peter    D           2014-12-13
John     B           2014-12-12

我想如下所示显示结果。没有显示相同的名称

Name     Project           Date
Peter       A            2014-12-11
            C            2014-12-12
            D            2014-12-13
John        B            2014-12-12

我的数据库服务器是MS SQL server 2012标准。如何通过SQL查询得到上述结果

谢谢

您可以使用ROW\U NUMBER函数执行以下操作

使用window函数查找每个groupname中的第一个日期

SELECT CASE WHEN rn = 1 THEN Name ELSE '' END Name,
       Project,
       Dates
FROM   (SELECT Row_number()OVER (partition BY Name ORDER BY Dates) rn,*
        FROM   Tablename) a 

;WITH CTE AS
(
   SELECT Name As OldName, Project, Date, 
          Row_Number() OVER (Partition By Name Order By Project) rn
   From YourTable
)
SELECT CASE WHEN rn = 1 THEN OldName ELSE '' End Name, Project, Date
FROM CTE
ORDER BY OldName, rn

SELECT CASE WHEN rn = 1 THEN Name ELSE '' END Name,
       Project,
       Dates
FROM   (SELECT Row_number()OVER (partition BY Name ORDER BY Dates) rn,*
        FROM   Tablename) a
