此方法是借用Excel中Range对象的CopyFromRecordset方法实现数据的导出,将 ADO 或 DAO Recordset(记录集) 对象的内容复制到工作表中(从指定区域的左上角开始)。 如果 Recordset 对象包含具有 OLE 对象的字段,则该方法无效。此方法还有一个缺点,就是导出数据到Excel时不带有标题,需要自己处理增加字段标题。
关于此方法的使用我写了一个专门的函数,可以直接调用便于数据导出至Excel,调用方法如下:
ExportToExcelCopyFromRecordset "Products", "select [Supplier IDs],ID,[Product Code],[Product Name],[Description] from Products"
"Products" 就指工作薄的名称。
"select [Supplier IDs],ID,[Product Code],[Product Name],[Description] from Products" 是需要导出数据的SQL语句。
函数说明:
'=========================================================================================
'函数名称: ExportToExcelCopyFromRecordset
'功能描述: 将 ADO 或 DAO 记录集对象中的内容复制到Excel工作表
'输入参数: WorkbookName 必需的,工作簿名称
' strSQL 必需的,SQL语句,不能包含具有 OLE 对象的字段,否则该方法无效。
'返回参数: 无
'使用说明: 由于采用的复制粘贴数据的方法,所以如果要导出子窗体数据,必须先让子窗体获得焦点
' 如果是导出主窗体数据,则主窗体中的焦点控件不能是子窗体,必须先将焦点从子窗体移开
