SQL清洁repeted导致一列

Question

我有这样的查询结果，有两列，BU和OPTION

BU OPTION 
A  1 
A  2 
A  3 
B  1 
B  2 
B  3 

有什么办法来获得这样的结果呢？

BU OPTION 
A  1 
     2 
     3 
B  1 
     2 
     3 

非常感谢。

Answer 1

虽然这将在呈现更好地处理层，你仍然可以通过

SELECT case when rw = 1 THEN Bu ELSE '' END AS BU, Option FROM (

SELECT ROW_NUMBER() over (partition by bu order by bu, option) as rw, * FROM #AA 
) X 

Answer 2

with CTE as 
(
select MT.*, row_number() over(partition by MT.BU order by MT.Option) as rn 
from MyTable 
) 
select case when rn = 1 then BU else null end as BU, 
     CTE.Option 
from CTE 

但作为Jarlh说，这是最好的表现层处理

Answer 3

我认为卜时可见选项= 1

select 
(case when option = 1 then bu else '' end) as bu, 
option 
from your_table
