并非所有Recordsets都支持Index和Seek。你确定用适当的参数打开了Recordset吗？

按照Seek Method and Index Property Example (VB)的这个例子。确保使用相同的参数来打开Recordset。

 rstEmployees.Open strSQLEmployees, strCnxn, adOpenKeyset, adLockReadOnly, adCmdTableDirect 

然后使用此代码段查看是否支持Index和Seek：

' Does this provider support Seek and Index?  
If rs1.Supports(adIndex) And rs1.Supports(adSeek) Then  
    MsgBox "Success: Seek and Index are Supported"
Else
   MsgBox "Failure:  Seek and Index are not Supported"
End If
