关于修改和添加数据问题（ADOTABLE)

Question

想修改数据库最后一条记录的一个字段，同时再新增加一条记录，
form2.DataSource2.Edit;
     form2.ADOTable2.Last;
     form2.ADOTable2.FieldByName('endtime').AsDateTime:=datetimepicker1.DateTime;
     form2.adotable2.post;
     form2.adotable2.edit;
     form2.ADOTable2.insert;
     form2.ADOTable2.FieldByName('no').AsString:=form2.ADOTable1.fieldbyname('number').asstring;
     form2.ADOTable2.Post;
这些代码是不行的，不知道哪位高手能做到！

Answer 1

With Form2.ADOTable2 do
begin
  Last;
  Edit;
  FieldByName('id').Asstring := Edit1.text;
  FieldByName....
  Post;
  Append;
  FieldByName('id').Asstring := Edit1.text;
  FieldByName....
  Post;
end;

气死我了，又没有显示全部
With Form2.ADOTable2 do
begin
  Last;//先定位
  Edit;//然后修改
  FieldByName('endtime').AsDateTime:=datetimepicker1.DateTime;//修改值
  post;//提交
  insert;//插入   APPEND;//在最后增加
 FieldByName('no').AsString:=form2.ADOTable1.fieldbyname('number').asstring;//赋值
  Post;
end;
