作爲額外行

Question

任何技巧任何人都可以就如何見下表

ID TYPE Name Description 
1 X A DESC_A 
2 X B DESC_B 
3 Z C DESC_C 

操縱這個觀點，分享創建鮮明的列值？

NAME_X DESCRIPTION_X 
A  DESC_A 
B  DESC_B 
NAME_Z DESCRIPTION_Z 
C  DESC_C 

對於每一個不同的專欄中，我想創建一個自定義列在「類型」列中的每個不同的值。在此示例中，通過將TYPE值附加到「NAME_」和「DESCRIPTION_」來創建自定義行。

謝謝！從視圖中選擇時

alter view dbo.yourView 
as 
with c_Distinct([type]) 
as ( select distinct [Type] 
     from dbo.yourTable 
    ) 
select [Sort] = 0, 
     [Type], 
     Name, 
     [Description] 
from dbo.yourTable 
union all 
select [Sort] = 1, 
     [Type], 
     'NAME_'+[Type], 
     'DESCRIPTION_'+[Type] 
from c_Distinct 

然後進行排序：

Answer 1

編輯：從視圖返回一些元數據

select * 
from yourView 
order by [Type] asc, [Sort] desc 

Answer 2

試試這個：

create view vwTestDistinctData 
as 
    select [type], [Description] 
    from testdistinctdata 
    union all 
    select 
     'NAME_' + [type] as [Type], 
     'DESCRIPTION_' + [type] as [Description] 
    from testdistinctdata 
    group by [type] 
go
