Question

我一直在尝试这项工作。我希望显示最新的数据，因为我希望在去年同一天的同一天显示

Jul 7 2016     
Jul 6 2016    
Jul 5 2016    
Jul 4 2016    
Jul 3 2016     
Jul 2 2016    
Jul 1 2016  

Jul 7 2015     
Jul 6 2015    
Jul 5 2015    
Jul 4 2015    
Jul 3 2015     
Jul 2 2015    
Jul 1 2015

这是我的代码：现在显示所有2015年的记录，我希望它像上面那样显示最新。

SELECT        
    OrderStatus, Sum_SellPrice, Sum_SellerMargin, Sum_BuyPrice, 
    OrderPeriodMonthName, OrderDate
FROM
    Sum_OrderCharges
WHERE        
    (OrderStatus IN ('Completed', 'Invoiced', 'Open')) 
    AND (OrderPeriodYear IN ('2016','2015')) 
    AND (MONTH(OrderDate) = MONTH(GETDATE()))
ORDER BY 
    OrderDate

Answer 1

SELECT        OrderStatus, Sum_SellPrice, Sum_SellerMargin, Sum_BuyPrice, OrderPeriodMonthName, OrderDate
FROM            Sum_OrderCharges
WHERE        (OrderStatus IN ('Completed', 'Invoiced', 'Open')) AND (OrderPeriodYear IN ('2016','2015')) AND (MONTH(OrderDate) = MONTH(GETDATE()))

       AND DAY(OrderDate) <= DAY(GETDATE())

ORDER BY OrderDate

note DAY()将返回介于1和1之间的整数。 31不是实际日期，因此您可以使用它来比较并进一步将结果限制为实际发生的日期。

我相信你会将以下内容附加到where子句： AND (OrderDate <= GETDATE())

完全是：

SELECT        OrderStatus, Sum_SellPrice, Sum_SellerMargin, Sum_BuyPrice, OrderPeriodMonthName, OrderDate
FROM            Sum_OrderCharges 
WHERE        (OrderStatus IN ('Completed', 'Invoiced', 'Open')) AND (OrderPeriodYear IN ('2016','2015')) AND (MONTH(OrderDate) = MONTH(GETDATE())) 
ORDER BY OrderDate

不需要：我会将其格式化为以下内容，以便您可以更好地了解where子句中的所有内容。（更容易看到所有开括号和右括号）

SELECT        OrderStatus
              ,Sum_SellPrice
              ,Sum_SellerMargin
              ,Sum_BuyPrice
              ,OrderPeriodMonthName
              ,OrderDate
FROM          Sum_OrderCharges 
WHERE         (OrderStatus IN ('Completed', 'Invoiced', 'Open'))
              AND (OrderPeriodYear IN ('2016','2015'))
              AND (MONTH(OrderDate) = MONTH(GETDATE()))
              AND (OrderDate <= GETDATE()) 
ORDER BY      OrderDate
