SQL命令順序重複

Question

我通過了zoneid我的SQL

ZoneID  | Description | 
1   | something |  
1   | something | 
1   | something |    
2   | something | 
2   | something |   
2   | something |  
3   | something | 
3   | something | 
3   | something | 

有訂單，但我想訂像這樣，有可能

ZoneID  | Description | 
1   | something |  
2   | something | 
3   | something | 
1   | something | 
2   | something |   
3   | something | 
1   | something | 
2   | something |   
3   | something | 

Answer 1

在SQL Server中，你可以使用row_number()

select ZoneId, Description 
from t 
order by row_number() over (partition by ZoneId order by (select 1)), ZoneId

回報：

+--------+-------------+ 
| ZoneId | Description | 
+--------+-------------+ 
|  1 | something | 
|  2 | something | 
|  3 | something | 
|  1 | something | 
|  2 | something | 
|  3 | something | 
|  1 | something | 
|  2 | something | 
|  3 | something | 
+--------+-------------+

在視圖中使用它（如果你不能order by沒有top），只需添加一列與row_number()：

create view dbo.with_rownumber as 
select 
    ZoneId 
    , Description 
    , rn = row_number() over (partition by ZoneId order by (select 1)) 
from t; 

go 
select ZoneId, Description 
from dbo.with_rownumber 
order by rn, ZoneId
