【问题描述】：

问题：我不断收到以下语句的语法错误：

CurrentDb.Execute "INSERT INTO Inventory ([Part #], [Year], [Week], [In], [Out]) " _ 
                & "VALUES ('" & Me.txtFindPart & "'," & Me.txtYear & "," & i & "," _ 
                & Me.Controls("in" & i) & "," & Me.Controls("out" & i) & ");"

现在我有一种感觉，是 Me.Controls 函数不断抛出此错误，但我无法让它消失。

上下文：这是一个更新按钮，它检查是否有记录，表单中的两个空格是否为空和 strong> 如果这两个条件都不满足，它将创建一个新记录。

现在发生这种情况时，文本框 in# 和 out# 中的数据将用于创建新记录。

守则：

Dim i As Integer
i = 1

Do Until i = 53

    If DCount("[Part #]", "[Inventory]", "([Inventory].[Part #] = '" & txtFindPart & "' AND [Inventory].[Year] = " & txtYear & " AND [Inventory].[Week] = " & i & ")") > 0 Then
        CurrentDb.Execute "UPDATE Inventory SET [In] = '" & Me.Controls("in" & i) & "' WHERE [Part #] = '" & txtFindPart & "' AND [Year] = " & txtYear & " AND [Week] = " & i & ";"
        CurrentDb.Execute "UPDATE Inventory SET [Out] = '" & Me.Controls("out" & i) & "' WHERE [Part #] = '" & txtFindPart & "' AND [Year] = " & txtYear & " AND [Week] = " & i & ";"
        i = i + 1
    ElseIf Me.Controls("in" & i) = Null And Me.Controls("out" & i) = Null Then
        i = i + 1
    Else
        CurrentDb.Execute "INSERT INTO Inventory ([Part #], [Year], [Week], [In], [Out]) " _
                        & "VALUES ('" & Me.txtFindPart & "'," & Me.txtYear & "," & i & "," _
                        & Me.Controls("in" & i) & "," & Me.Controls("out" & i) & ");"
        i = i + 1
    End If
Loop
Me.Requery

【问题讨论】：

您的表单上是否真的有名为：in1, in2, in3, in4... 和 out1, out2, out3, out4... 的文本框？您是否还会收到特定的语法错误？
运行时错误 '3134' INSERT INTO 语句中的语法错误。
@user2517352：将CurrentDb.Execute 替换为Debug.Print。这会将您所有的实际 SQL 语句输出到即时窗口中。然后，编辑您的问题并粘贴一两条 SQL 语句，以便我们可以看到实际执行的 SQL。
当我替换代码并单击我的按钮时，它什么也没做。没有执行任何操作，没有更新或添加任何内容，也没有错误消息或弹出窗口。

【解决方案1】：

试试这个：

Dim i As Integer
i = 1

Do Until i = 53
    If DCount("[Part #]", "[Inventory]", "[Inventory].[Part #] = '" & txtFindPart & "' AND [Inventory].[Year] = " & txtYear & " AND [Inventory].[Week] = " & i & "") > 0 Then
        CurrentDb.Execute "UPDATE Inventory SET [In] = '" & Me("in" & i).Value & "', [Out] = '" & Me("out" & i).Value & "' WHERE [Part #] = '" & txtFindPart & "' AND [Year] = " & txtYear & " AND [Week] = " & i & ";"
    ElseIf Not IsNull(Me("in" & i).Value) And IsNull(Me("out" & i).Value) Then
        CurrentDb.Execute "INSERT INTO Inventory ([Part #], [Year], [Week], [In], [Out]) " _
                        & "VALUES ('" & Me.txtFindPart & "'," & Me.txtYear & "," & i & ",'" _
                        & Me("in" & i).Value & "','" & Me("out" & i).Value & "');"
    End If
    i = i + 1   
Loop
Me.Requery

运行时错误 3075 查询表达式中的语法错误（缺少运算符）“100，[Out] = '50' WHERE [Part #] = '1' AND [Year] = 2015 AND [Week] = 1;'.
好吧，有了这么少的信息，你让我们猜测。
@Gustav：该错误来自您的答案代码中的UPDATE 查询，因为您在SET [In] = '" & Me("in" & i).Value & " 之后缺少'
感谢克里斯蒂安。编辑；它现在存在。
我想通了。我也没有在需要的地方处理空值。
