VBA利用<em>ADO</em>操作<em>excel</em>求教

简单的办法是，打开宏录制，操作数据连接，数据连接成功后，停止宏录制，然后查看宏的内容，里面应该会有你需要的VBA代码。

conn.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & ThisWorkbook.FullName & ";Extended Properties='Excel 12.0;HDR=YES;IMEX=1'"
试试
先来个临时存储，再删除，再添加修改好的。具体代码如下：
'//sql语句导出到excel
'//参数：strSQL－传入的sql语句，strTitle-对应sql语句中每列的标题(例如："编号|名称|规格")
Public Function SQLToExcel(ByVal strSQL As String, ByVal strTitle As String)
Dim rsTemp As ADODB.Recordset
Dim strExcelPath As String '//导出的excel文件路径
Dim arrTemp() As Variant
Dim arrTitle As Variant
Dim lngRows As Long
Dim lngCols As Long
Dim objExcelApp As Object
Dim objExcelWorkBook As Object
Dim objExcelWorkSheet As Object
Dim i As Long

在日常生活中,通常有很多表格文件用Excel存放,访问Excel表格的方法很多,在Delphi中可以通过Servers中的ExcelApplication,ExcelWorkBook,ExcelWorkSheet等控件操纵Excel中的数据.但是我copy们无法用ADO操纵Excel文件百中的Sheet,ADO控件会告诉你"[microsoft][OdbC Excel driver]Microsoft Jet 数据库引擎找不到对象'Sheet1'.请确定对象是否存在,并正确地写出它的名称和路径.
那么如何才能正确的操纵Excel呢???
首先用度ADO连接Excel,至于怎么连接Excel我想不用我说了吧.
然后这个是个关键:打开Excel,先"插入"->"名称"->"定义",如图:

输入一个名称,如:OK,按"添加"按钮,然后指定引用位置,如图:

最后按"确定",然后存盘,这关知键的一步就算完成了.
现在你在Delphi中就可以通过ADOQuery或ADOTable等自由操纵表名为"OK"的表了.

注意:1.你可以在一个Excel文件中定义多个名称,当多个表使用
2.此方法不能用道于Excel中的Chart等元素
