如何通过sql Query按顺序放置条件

Question

这是我的表名： - xyztable，在这张表中我有3列

A： - id
B： - 姓名
c： - Order_number

我有像

这样的样本数据

Id Name order_nmber  
1  A    1  
2  K    0  
3  B    6  
4  c    3  
5  P    0  
6  d    5  
7  e    2  
8  O    0  

我写的查询是

select  * from xyztable order by order_number ASC;

给我的结果是

Id Name order_nmber 
2  K    0
5  P    0
8  O    0
1  A    1
7  e    2
4  c    3 
6  d    5
3  B    6 

但我希望结果如下： -

Id Name order_nmber 
1  A    1
7  e    2
4  c    3 
6  d    5
3  B    6
2  K    0
5  P    0
8  O    0

那我怎么能在单个查询中得到这个....请帮助!!!!

你可以这样做：

select  * from xyztable 
order by  case when order_number=0 then 1 else 0 end ASC, order_number ASC;

尝试这样的事情：
