Question

我正在尝试找出在接下来的5天内查看到期订单的最佳方式

如果我输入-10而不是+10，我的代码就有效，所以我对我的错误感到有些困惑

EG，我过去10天的代码工作正常

select  
    PurchaseOrder, OrderDueDate
from 
    PorMasterHdr
where 
    OrderDueDate between DATEADD(day, datediff(DAY, 0, GETDATE()) -10, 0)
                     and DATEADD(day, datediff(day, 0, GETDATE()),  0) 
order by 
    OrderDueDate desc

但在接下来的10天内，返回0行 - 肯定会在未来10天内到期的项目

select  
    PurchaseOrder, OrderDueDate 
from  
    PorMasterHdr
where 
    OrderDueDate between DATEADD(day, datediff(DAY, 0, GETDATE()) +10, 0)
                     and DATEADD(day, datediff(day, 0, GETDATE()),  0) 
order by 
    OrderDueDate desc

任何帮助都将不胜感激。

Answer 1

您应该在开始/结束表达式之间切换。

代码应如下所示：

select  PurchaseOrder, OrderDueDate 
from PorMasterHdr
where OrderDueDate between
DATEADD (day,datediff(DAY,0,GETDATE()), 0)
AND
dateadd(day,datediff(day, 0 ,getdate()) +10,  0) 
order by OrderDueDate desc

Answer 2

应该首先是最短的日期，即＆＃34; 2014-11-01＆＃39;和＆＃39; 2014-11-10＆＃39; ＆＃34;是正确的和＆＃34;在2014-11-10之间＆＃39;和＆＃39; 2014-11-01＆＃34;是错的

所以你的查询是：

select 
    PurchaseOrder, OrderDueDate 
from 
    PorMasterHdr 
where 
    OrderDueDate between dateadd(day, datediff(day, 0, getdate()), 0) 
                     and dateadd(day, datediff(DAY, 0, GETDATE()) +10, 0)
order by 
    OrderDueDate desc

SQL Server Datepart之间，下一个＆＃39; x＆＃39;天
