我这里有个从ORACLE导出到EXCEL的例子，希望有帮助
Private Function ExportDetail(strFileName As String) As Boolean
Dim iRow As Long
Dim myExcel As Excel.Application
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet
On Error GoTo ErrAction
ExportDetail = False
Set myExcel = New Excel.Application
myExcel.Visible = False
myExcel.SheetsInNewWorkbook = 1
Set xlBook = myExcel.Workbooks.Add
Set xlSheet = xlBook.Worksheets(1)
xlSheet.Columns.ClearFormats
xlSheet.Cells(1, 1) = "物料BOM【" & TreeFile.SelectedItem.Text & "】"
xlSheet.Range("A1:T1").MergeCells = True
xlSheet.Cells(2, 1) = "标题项"
xlSheet.Cells(2, 2) = "中文名称"
xlSheet.Cells(2, 3) = "英文名称"
xlSheet.Cells(2, 4) = "文档号"
xlSheet.Cells(2, 5) = "物料号"
xlSheet.Cells(2, 6) = "数量"
xlSheet.Cells(2, 7) = "总数量"
xlSheet.Cells(2, 8) = "单位"
xlSheet.Cells(2, 9) = "物料关联文档1"
