【问题描述】：
我正在开发一个 Excel 应用程序，它允许用户通过用户表单输入工作时间，并且信息存储在 Access DB 中。我是 excel 和访问连接的新手。我能够连接到数据库，但由于 .Update 命令 处的运行时错误，未保存/创建记录。 运行时错误“-2147467259 (80004005)”：操作必须使用可更新查询。
我已经搜索和搜索，但找不到解决此问题的方法。我希望有人能够提供帮助。 （代码如下）
Sub Export_Data_Access_TI1()
Dim dbPath As String
Dim x As Long, i As Long
Dim nextrow As Long
Dim user As String
Dim NewSht As Worksheet
Dim strQuery As String
Dim recDate As String
Dim Week_Of As String
user = Sheet1.Range("A1").Text
On Error GoTo ErrHandler:
'Variables for file path and last row of data
dbPath = "H:\PROJECTS\CAI_DOT-Time Tracker\CAI_EMP_SignIn_Database.accdb"
nextrow = Cells(Rows.Count, 1).End(xlUp).Row
'Initialise the collection class variable
Set cnn = New ADODB.Connection
'Check for data
If Sheets(user).Range("A2").Value = "" Then
MsgBox " There is no data to send to MS Access"
Exit Sub
End If
cnn.Mode = adModeReadWrite

Set rst = New ADODB.Recordset 'assign memory to the recordset
rst.CursorLocation = adUseClient

'rst.Supports (adAddNew)
x = 2 'the start row in the worksheet
Do While Len(Sheets(user).Range("A" & x).Formula) > 0

.AddNew 'create a new record

End With

-
您是否在查询中包含主键？如果您希望它可更新，这是必需的。

您好 braX，是的，包括主键（UniqueID）。感谢您的回复。
