SQL Server +不正确的TOP 1输出

Question

我有一部分查询，如下所示，TOP 1应该在2条记录中共享，因为有2个网点具有相同的访问计数。显然，查询只会返回一条记录。在这种情况下，我如何显示“准确”的输出？

Select TOP 1 (O.Name) as MostVisited 
     From [Trans] T 
      INNER JOIN [Outlet] O 
      On (T.Outlet_Code = O.Code) 

     Where [VoidBy] IS NULL AND [VoidOn] IS NULL AND CardNo In  
      (Select [CardNo] From [Card] Where [CardNo] = 'CARDX' AND [MemberID] = @MemberId) 
     Group by O.Name  
     Order by Count(T.Outlet_Code) Desc 

Answer 1

Select TOP (1) WITH TIES (O.Name) as MostVisited 
     .... 

WITH TIES提供 “联合顶” 的情况。

例子：

DECLARE @t TABLE (foo int, qty int); 
INSERt @t VALUES (1, 100), (3, 200), (2, 200); 

-- one row, arbitrary 
SELECT TOP (1) * FROM @t ORDER BY qty DESC; 

-- both rows with "TOP 1 value" 
SELECT TOP (1) WITH TIES * FROM @t ORDER BY qty DESC;
