我有两个几乎相同的数据库（第二个是第一个的副本，然后用不同的公司/产品信息进行了修改）。有一个老化报告从来没有正常工作，我必须修复。我让它在一个数据库（A）上工作，但第二个（B）引发了“无效”错误。

报表查询是从另一个查询生成的，它基本上是抓取订单信息和客户信息。从那里，有问题的查询根据订单的发货时间将订单分成几块，并返回余额。错误消息弹出以下代码段：

Round(Sum(IIf((Date()-[ShipDate] Is Null),[LineTotal]+(CLng([LineTotal]*[SalesTaxRate]*100)/100)+[FreightCharge]-nz([Total Payments]),0)),2) AS Current_Unshipped

如果 Is Null 更改为其他任何值，则查询将正常执行。如果我尝试引入任何“如果变量为空”代码，则会引发错误。我尝试了以下方法，但无济于事。

Round(Sum(IIf((nz[ShipDate]),[LineTotal]+(CLng([LineTotal]*[SalesTaxRate]*100)/100)+[FreightCharge]-nz([Total Payments]),0)),2) AS Current_Unshipped

如果发货日期为空，我还有另一列会返回“NULL”，这出乎意料地有效。第一个代码段在另一个数据库中完美运行，所以我很困惑。我需要能够为未发货的订单生成一列，因此缺少 [ShipDate]。我不知道为什么代码不起作用。

整体

(CLng([LineTotal]*[SalesTaxRate]*100)/100)+[FreightCharge]-nz([Total Payments]),0))

代码的一部分是余额是如何生成的，它是如何工作的。它还在数据库中大约一百万个位置实现——设计者认为每次运行查询时都会自动生成总余额，而不是存储在某个地方。

整个查询代码也发布在下面。如果有人能指出我正确的方向，那将有很大帮助。

SELECT DISTINCTROW 
    Round(Sum(IIf((Date()-[ShipDate]<31),[LineTotal]+(CLng([LineTotal]*[SalesTaxRate]*100)/100)+[FreightCharge]-nz([Total Payments]),0)),2) AS [Current],
    Round(Sum(IIf((Date()-[ShipDate] Is Null),[LineTotal]+(CLng([LineTotal]*[SalesTaxRate]*100)/100)+[FreightCharge]-nz([Total Payments]),0)),2) AS Current_Unshipped,
    Round(Sum(IIf((Date()-[ShipDate])<61 And (Date()-[ShipDate]>30),[LineTotal]+(CLng([LineTotal]*[SalesTaxRate]*100)/100)+[FreightCharge]-nz([Total Payments]),0)),2) AS [31-60 Days], 
    Round(Sum(IIf((Date()-[ShipDate])<91 And (Date()-[ShipDate]>60),[LineTotal]+(CLng([LineTotal]*[SalesTaxRate]*100)/100)+[FreightCharge]-nz([Total Payments]),0)),2) AS [61-90 Days],

用这个：

Round(Sum(IIf(DateDiff("d",Date(),[ShipDate])=0,[LineTotal]+CLng([LineTotal]*[SalesTaxRate]*100)/100+[FreightCharge]-Nz([Total Payments],0),0)),2) AS Current_Unshipped
