如何从函数返回记录集

我正在Excel VBA中构建数据访问层,返回记录集时遇到问题。我的类中的execute()函数确实在从数据库中检索行,但似乎没有返回任何内容。

以下函数包含在一个名为dataaccesslayer的类中。类包含函数connect和disconnect,后者处理打开和关闭连接。

Public Function Execute(ByVal sqlQuery As String) As ADODB.recordset
    Dim rs As ADODB.recordset
    Set rs = New ADODB.recordset
    Dim recordsAffected As Long

    ' Make sure we're connected to the database.
    If Connect Then
        Set command = New ADODB.command

        With command
            .ActiveConnection = connection
            .CommandText = sqlQuery
            .CommandType = adCmdText
        End With

        'Set rs = command.Execute(recordsAffected)
        'Set Execute = command.Execute(recordsAffected)
        rs.Open command.Execute(recordsAffected)
        rs.ActiveConnection = Nothing
        Set Execute = rs
        Set command = Nothing
        Call Disconnect
    End If
End Function

这是一个公共函数,我在电子表格的单元格A1中使用它进行测试。

Public Function Scott_Test()
    Dim Database As New DataAccessLayer
    'Dim rs As ADODB.recordset
    'Set rs = CreateObject("ADODB.Recordset")
    Set rs = New ADODB.recordset

    Set rs = Database.Execute("SELECT item_desc_1 FROM imitmidx_sql WHERE item_no = '11001'")
    'rs.Open Database.Execute("SELECT item_desc_1 FROM imitmidx_sql WHERE item_no = '11001'")
    'rs.Open

    ' This never displays.
    MsgBox rs.EOF

    If Not rs.EOF Then
        ' This is displaying #VALUE! in cell A1.
        Scott_Test = rs!item_desc_1
        rs.Close
    End If

    rs.ActiveConnection = Nothing
    Set rs = Nothing
End Function

我做错什么了?
