sql-server - 前 10 名的 SQL 中的 While 循环

Question

现在，我正在尝试通过循环从表中获取前 10 个数据。

 Select ClientUserName, DestHost, count(DestHost) counts  from  #ProxyLog_record  
 where ClientUserName =(Select top 1 ClientUserName from #ProxyLog_count_2) 
 Group by ClientUserName, DestHost order by counts desc 

这仅从 clientusername 获取顶级数据我如何将它循环到它将获得第一个、第二个第三个、....第十个数据的位置？

Answer 1

 Group by ClientUserName, DestHost order by counts desc LIMIT 10

Answer 2

您不能循环，但您可以执行以下操作并更改要在子查询中选择的记录数：

   Select ClientUserName, DestHost, count(DestHost) counts  from  #ProxyLog_record  
     where ClientUserName  in (Select top 10 ClientUserName from #ProxyLog_count_2) 
     Group by ClientUserName, DestHost order by counts desc
