[嗨，我想知道为什么Copyfromrecordset无法正常工作是否可以使用ADO？
我只有一个表一数字列，它不接受重复项。还需要检索ID号，以供其他代码用于多用户用途。
Sub PostData()
Dim cnn As ADODB.Connection 'dim the ADO collection class
Dim rst As ADODB.Recordset 'dim the ADO recordset classe here
Dim dbPath
Dim x As Long, i As Long
'add error handling
On Error GoTo errHandler:
dbPath = Sheets("Sheet3").Range("h1").Value
Set cnn = New ADODB.Connection
cnn.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & dbPath
Set rst = New ADODB.Recordset 'assign memory to the recordset
Sql = "INSERT INTO DvID(DVnumber)SELECT Max(DVNumber)+1 FROM DvID "
rst.Open Sql, cnn
Sheet3.Range("A2").CopyFromRecordset rst
rst.Close
cnn.Close
Set rst = Nothing
Set cnn = Nothing
On Error GoTo 0
Exit Sub
errHandler:
Set rst = Nothing
Set cnn = Nothing
MsgBox "Error " & Err.Number & " (" & Err.Description & ") in procedure Export_Data"
End Sub
