我是靠谱客的博主爱听歌微笑，最近开发中收集的这篇文章主要介绍Excel VBA连接并操作Oracle，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

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：

复制代码代码如下:
