SQL清潔repeted導致一列

Question

我有這樣的查詢結果，有兩列，BU和OPTION

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

有什麼辦法來獲得這樣的結果呢？

BU OPTION 
A  1 
     2 
     3 
B  1 
     2 
     3 

非常感謝。

Answer 1

雖然這將在呈現更好地處理層，你仍然可以通過

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 

但作爲Jarlh說，這是最好的表現層處理

Answer 3

我認爲卜時可見選項= 1

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