Excel VBA連接并操作Oracle

更新時(shí)間：2009年08月05日 22:55:34 作者：

Excel通過ADO方式連接到Oracle并操作Oracle給我們這些編程能力不強(qiáng)的人帶來很大的福音，結(jié)合著Excel的數(shù)據(jù)處理與圖表制作，就能很輕松地處理一些常規(guī)工作。

以下是通過Excel 的VBA連接Oracle并操作Oracle相關(guān)數(shù)據(jù)的示例
Excel 通過VBA連接數(shù)據(jù)庫需要安裝相應(yīng)的Oracle客戶端工具并引用ADO的相關(guān)組件，引用ADO相關(guān)組件可按如下步驟操作：
　　1、打開VBA編輯器，在菜單中點(diǎn)選“工具”，“引用”；
　　2、確?！癕icrosoft ActiviteX Data Objects 2.8 Library”和“Microsoft ActiviteX Data ObjectS Recordset 2.8 Library”被勾選上。
　　建立連接過程，代碼如下：

復(fù)制代碼代碼如下:
