B： - 名字
c： - Order_number

我有一個樣本數據

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

我寫的查詢是

select  * from xyztable order by order_number ASC;

給我的結果是

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

但我想要的結果如下： -

Id Name order_nmber

4  c    3 
6  d    5
3  B    6
2  K    0
5  P    0
8  O    0

那我怎么能在單個查詢中得到這個....請幫助!!!!
