我正在构建一个应用程序来跟踪项目，员工等的时间。我工作的公司有重要的安全繁文缛节，所以我必须使用MS Access 2016，我被禁止从youtube搜索解决方案，我无法下载任何文件来自网络。幸运的是，我仍然可以访问StackOverflow。
我有一个带有按钮的输入表单（“Task_List_Entry_Form”）。单击时，该按钮将值发送到表（“tbl_Task_List”）。在VBA的形式中，我已经包括表（“tbl_Task_List”）刷新，并且所有值都转到另一个充当更正日志的表（“tbl_Task_List_Corrections”）。但是多值字段（我知道，它们是最糟糕的，如果它不是看似必要的东西，我不会包括它们）不能去。所以我在VBA中包含了第二个查询来获取多值字段的值并输入到字段中，但到目前为止这一点都没有成功。
第一个查询选项如下所示：
strSQL2 = "INSERT INTO tbl_Task_List_Corrections " & Tags.Value & " FROM tbl_Task_List " & "WHERE tbl_Task_List.ID IN (SELECT MAX(tbl_Task_List.ID) FROM tbl_Task_List);"
'DoCmd.RunSQL strSQL2
结果：抛出错误“运行时错误'3134'：INSERT INTO语句中的语法错误”，错误在线“DoCmd.RunSQL strSQL2”，非多值字段正确传输，但未拉出值， tbl_Task_List_Corrections.Tags字段保持为NULL。
然后我尝试了更像这样的东西：
CurrentDb.Execute "INSERT INTO tbl_Task_List_Corrections (Tags) VALUES ('" & Me.[Tags].Value & "');"
结果：未引发任何错误，但未提取该值，并且在“tbl_Task_List_Corrections”表中插入了一个额外的行
可能有一个我可以尝试的第三个解决方案，我在这个源上找到了，但它是基于一个示例访问数据库，由于安全限制，我无法下载和查看，我无法从中找出它仅代码。这是来源：https://www.utteraccess.com/forum/index.php?s=66e048c0880b46f8bd25a0541c30df63&showtopic=2018212&st=0&p=2463687&#entry2463687
这不是所有代码，而是保存表单后与移动值有关的代码。

结果比我想象的要简单得多。看起来原始尝试是正确的。
一旦创建了具有非MVF数据的新记录，运行另一个INSERT SELECT操作来填充MVF。示例显示在复制记录的循环中填充第二个表MVF。经过测试和工作。应该很容易为表单上的记录标识符指定的单个记录执行SQL操作，而不是循环记录集。
Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT RateID FROM CopyOfRates")
Do Until rs.EOF
CurrentDb.Execute "INSERT INTO CopyOfRates(MVTest.Value) SELECT MVTest.Value FROM " & _
"(SELECT MVTest.Value FROM Rates WHERE RateID = " & rs!RateID & ") AS Q1 " & _
"WHERE CopyOfRates.RateID = " & rs!RateID
rs.MoveNext
