多次选择top(x)

Question

对不起,垃圾标题,但希望这将解释:

鉴于表

 name     |   data
---------------------
   1      |   1000
   1      |   2000
   1      |   3000
   2      |   1500
   2      |   2500
   2      |   3500

我希望能够为数据值排序的所有名称选择顶部(x).因此,如果x = 2,则返回

 name     |   data
---------------------
   1      |   2000
   1      |   3000
   2      |   2500
   2      |   3500
