SQL Order序数重复

Question

我在我的sql上通过zoneId订购了

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

但是我想这样订购它，它可能

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

在sql server中，您可以使用row_number()

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

返回：

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

要在视图中使用它（order by没有top），只需添加row_number()的列：

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
