数据提供程序或其他服务返回了E\u FAIL状态(vba mysql记录集)

当我试图将数据库表中的数据写入工作表时,出现以下错误。

Public Sub download_nodes()

    Dim pull As New QueryHandler
    Dim rst As Recordset

    'Get info from mysql into Recordset
    With pull
      .ConnectionString = "localhost"
      .SQLQuery = "SELECT * FROM `table_db`;"
      Set rst = .RetrieveQuery
    End With

    'Write data in worksheet "Test"
    If Not rst.EOF Then
        Sheets("Test").Range("A1").CopyFromRecordset rst
    End If

End Sub

你知道问题是什么吗?谢谢!
