mysql按字段排序并使用当前日期

Question

我有一张桌子

Id   ordertype   orderdate 
1    open         09/01/2014        
2    pending      09/01/2014        
3    open         09/30/2014        
4    closed       06/01/2014        
5    closed       9/15/20143        

我创建了一个mysql查询，按字段排序我想要的。

select * from table order by FIELD(ordertype, 'pending', 'open', 'closed'), orderdate

将按照

对上表进行排序

Id   ordertype   orderdate    
2    pending      09/01/2014 
3    open         09/30/2014 
1    open         09/01/2014         
5    closed       09/01/2014     
4    closed       06/01/2014  

先挂起，打开秒，然后在底部关闭。

但我想做的是根据今天的日期关闭。意思ID＃5将在2014年1月9日之前排在最前面，然后它会在其他已关闭的订单下降到最低点。

Id   ordertype   orderdate    
5    closed       09/01/2014 
2    pending      09/01/2014 
3    open         09/30/2014 
1    open         09/01/2014         
4    closed       06/01/2014  

感谢您的帮助

Answer 1

使用它：

select * from table order by FIELD(ordertype, 'pending', 'open', 'closed'), orderdate, orderdate desc

Answer 2

您可以使用案例表达式，例如

select * 
from table1 
order by
      case when ordertype = 'closed' and orderdate > curdate() then 0 else 1 end
    , FIELD(ordertype, 'pending', 'open', 'closed')
    , orderdate

nb：不确定您是否需要＆gt; curdate（）或＆gt; = curdate（）
