我正在创建一个VBA脚本的问题，我认为这是最好的问题。我将给出一些背景知识：
我正在编写这个程序，因为我的很多客户违反了我国税务局的定期发行文件并支付现金，然后让我计算该特定金额的税额。这是一个相当多的文书工作，手动解决，所以我正在编写一个应用程序来做到这一点，还有更多。下面的脚本是需要完成的工作的核心。
对于第一个用例，我基本上在Access中创建了一个单用形式 - 没有写入任何内容，只是用于临时计算并被发送到打印机 - 计算假期工资。
由于我无法在计算单元格中执行SQL查找，因此我正在运行一个VBA脚本来为我做繁重的工作，并将三个输入的值作为参数传递。
然而，我似乎无法摆脱3075的运行时错误，而我无法为我的生活找出它的来源。我已将其追溯到SQL语句，但我找不到会出现运算符错误的位置。我哪里错了？
以下是代码：
Option Compare Database
Public Function DetermineTax(CurrentDate As Date, CurrWageType As String, CalcNetWages As Currency)
'Checks whether required fields are blank
If Not (IsDate(CurrentDate)) Then
Exit Function
End If
If (CurrWageType = "") Then
Exit Function
End If
If (CalcNetWages <= CCur(0#)) Then
Exit Function
End If
Dim strSQL As String
'Calculates tax based on (-((n-b)/(a-1))-n) formula, where all WHERE arguments have been met.
strSQL =
"SELECT FIRST (ROUND(((-(CalcNetWages-tblWageRate.CoefficientB)/(tblWageRate.CoefficientA-1))-CalcNetWages))) " & _
"FROM tblWageType INNER JOIN tblWageRate " & _
"ON tblWageType.WageTypeID = tblWageRate.fk_WageTypeID " & _
"WHERE tblWageRate.TaxYearStart <= CurrentDate And " & _
"tblWageRate.TaxYearEnd >= CurrentDate And " & _
"tblWageType.WageType = CurrWageType And " & _
"tblWageRate.Net >= CalcNetWages;"
CurrentDb.Execute Query:=strSQL, Options:=dbFailOnError + dbSeeChanges
'DoCmd.RunSQL strSQL
End Function
当然，如果还有其他问题，我会回答它们。
谢谢！
编辑：呃，我一直在看这段代码太久了。 ROUND函数需要封装在括号中。摆脱了错误3075.我已将上面的代码修改为现在的位置。
但是现在我收到错误3065“无法执行选择查询”。通过一些初步的谷歌搜索似乎我不能在表单中使用SELECT字段，但我不认为这应该有所作为，因为我在模块中调用它。当我上床睡觉时，明天我会进一步尝试，但与此同时有人有任何想法吗？
答案 0 :(得分：0)
我最终在本周解决了我的问题。我认为问题是a）处理日期的方式和b）缺少引号。
这还包括我拥有的代码a）调用有问题的函数，b）将其附加到表中。
