如何用delphi程序实现，将EXCEL导入ACCESS数据库

Answer 1

procedure TF_Main.ToolButtonExcelClick(Sender: TObject);
var
  OpenDialog:TOpenDialog;
  iCount:integer;
begin
  if ShowIYN('是否真的要导入Excel数据,要生的数据将被删除?')<>IDCANCEL then
  try
    OpenDialog:=TOpenDialog.Create(Self);
    OpenDialog.DefaultExt := 'xls';
    OpenDialog.Filter := 'Microsoft Excel 文件  (*.xls)|*.xls';
    OpenDialog.Execute;
    if OpenDialog.FileName<>'' then
    try
      Screen.Cursor:=crSqlWait;
      ADOConExcel.Close;
      ADOConExcel.ConnectionString:='Provider=Microsoft.Jet.OLEDB.4.0;Data
Source='
                                        +OpenDialog.FileName+';Extended
Properties=Excel 8.0;Persist Security Info=False';
      ADOConExcel.Open;
      with ADOQryExcel do
      begin
        Close;
        Sql.Clear;
        Sql.Add('SELECT 材料编号,百平米用量,预算价,最低价 FROM
[Sheet1$]');
        Prepared:=true;
        Open;
      end;
      iCount:=ADOQryExcel.RecordCount;
      ADOConExcel.BeginTrans;
      with F_DataModule.ADOCom do
      begin
        CommandText:='DELETE FROM MatPriCal WHERE
cYearMonth='+''''+FormatDateTime('yyyymm',DateTimePicker.DateTime)+'''';
        Execute;
      end;
      ADOQryExcel.First;
      while not ADOQryExcel.Eof do
      begin
        with F_DataModule.ADOCom do
        begin
          CommandText:='INSERT INTO MatPriCal
VALUES('+''''+FormatDateTime('yyyymm',DateTimePicker.DateTime)+''''+','+''
''+Trim(ADOQryExcel.FieldByName('材料编号
').AsString)+''''+','+Trim(ADOQryExcel.FieldByName('百平米用量
').AsString)+','+Trim(ADOQryExcel.FieldByName('预算价
').AsString)+','+Trim(ADOQryExcel.FieldByName('最低价').AsString)+')';
          Execute;
        end;
        ADOQryExcel.Next;
        F_Main.StatusBar.Refresh;
        F_Main.StatusBar.Panels[2].text:='当前数
:'+IntToStr(ADOQryExcel.RecNo)+'(共'+IntToStr(iCount)+'条)';
      end;
      ADOConExcel.CommitTrans;
      ShowWIE(2,'导入成功!');
    except
      ADOConExcel.RollbackTrans;
      ShowWIE(2,'导入失败!');
    end;
  finally
    ADOQryExcel.Close;
    ADOConExcel.Close;
    OpenDialog.Free;
    Screen.Cursor:=crDefault;
    F_Main.StatusBar.Panels[2].Text:='';
  end;
end;

或用sql 自带的openrowset,参考程序
if ShowIYN('是否真的要导入Excel数据?')<>IDCANCEL then
  try
    ADOConInfoExcel.Open;
    OpenDialog:=TOpenDialog.Create(Self);
    OpenDialog.DefaultExt := 'xls';
    OpenDialog.Filter := 'Microsoft Excel 文件  (*.xls)|*.xls';
    OpenDialog.Execute;
    if OpenDialog.FileName<>'' then
    try
      with ADOQryInfoExcel do
      begin
        Close;
        Sql.Clear;
        Sql.Add(' SELECT TOP 1 * FROM OPENROWSET');
        Sql.Add('(');
        Sql.Add('''MSDASQL.1''');
        Sql.Add(',');
        Sql.Add('''DRIVER=Microsoft Excel Driver (*.xls);');
        Sql.Add('DBQ='+OpenDialog.FileName+'''');
        Sql.Add(',');
        Sql.Add('''SELECT * FROM [Sheet1$]''');
        Sql.Add(')');
        Open;
      end;
      if Copy(ADOQryInfoExcel.Fields[2].AsString,1,4)<>mUser.UserArea
then
      begin
        ShowWIE(1,'不能导入其它地区数据!');
        ADOQryInfoExcel.Close;
        ADOConInfoExcel.Close;
        exit;
      end;
      //ADOConInfoExcel.BeginTrans;
      with ADOComInfoExcel do
      begin
        CommandText:=' UPDATE C';
        CommandText:=CommandText+' SET C.MNo=A.类别编码,C.MName=A.材料名称

        Execute;
      end;

      RefreshGridData;
      ShowWIE(2,'导入成功!');
    except
      //ADOConInfoExcel.RollbackTrans;
      ShowWIE(2,'导入失败!');
    end;
  finally
    ADOQryInfoExcel.Close;
    ADOConInfoExcel.Close;
    OpenDialog.Free;
  end;
