比如在一个窗体里有一个“取消”和“确定”按钮,“取消”按钮批次取消所有修改,“确定”按钮批次提交:
1.设置QryDef(数据集)的LockType为ltBatchOptimistic,CursorType为ctStatic,CursorLocation为clUseClient
2.“确定”按钮的单击事件为:
  if QryDef.Connection.InTransaction then
  begin
    try
      QryDef.UpdateBatch();
      QryDef.Connection.CommitTrans;
    except
      QryDef.Connection.RollbackTrans;
    end;
  end;
3.“取消”按钮的单击事件为:
  QryDef1.CancelBatch;
4.初始插入数据:
  Qry.LoadFromFile(ExtractFilePath(Application.ExeName) + 'ClassifyDefine');
  {$IFDEF Test}codesite.SendMsg('3'); {$ENDIF}
  while not Qry.Eof do
  begin
    QryDef.Append;
    QryDef.FieldByName('name').AsString := Qry.FieldByName('name').AsString;
    if not Qry.FieldByName('Money1').IsNull then
   QryDef.FieldByName('Money1').AsCurrency := Qry.FieldByName('Money1').AsCurrency;
    if not Qry.FieldByName('Money2').IsNull then
   QryDef.FieldByName('Money2').AsCurrency := Qry.FieldByName('Money2').AsCurrency;
    QryDef.Post;
    Qry.Next;
  end;
  QryDef.UpdateBatch(); 

5.批处理方式其它实例:

procedure TForm1.Button1Click(Sender: TObject);
begin
adoconnection1.begintrans;
try
adoquery.close;
adoquery.sql.clear;
adoquery.sql.add(insert 语句);
adoquery.execsql;
如果还有insert 语句则:
adoquery.close;
adoquery.sql.clear;
adoquery.sql.add(insert 语句);
adoquery.execsql;直到所有insert 语句完成.
adoconnection1.committrans;
except
adoconnection1.rollbacktrans;
end;
end;
