Excel通过ADO方式连接到Oracle并操作Oracle给我们这些编程能力不强的人带来很大的福音，结合着Excel的数据处理与图表制作，就能很轻松地处理一些常规工作。

以下是通过Excel 的VBA连接Oracle并操作Oracle相关数据的示例
Excel 通过VBA连接数据库需要安装相应的Oracle客户端工具并引用ADO的相关组件，引用ADO相关组件可按如下步骤操作：
　　1、打开VBA编辑器，在菜单中点选“工具”，“引用”；
　　2、确保“Microsoft ActiviteX Data Objects 2.8 Library”和“Microsoft ActiviteX Data ObjectS Recordset 2.8 Library”被勾选上。
　　建立连接过程，代码如下：

代码如下:

Dim ConnDB As ADODB.Connection 
Set ConnDB = New ADODB.Connection 
Dim ConnStr As String 
Dim DBRst As ADODB.Recordset

Dim SQLRst As String 
Dim OraOpen As Boolean 
OraOpen = False
