本文介绍了一种批量数据处理的方法，通过遍历查询节点并使用复制服务进行数据转换，然后将转换后的数据添加到输入数据集，并执行相应的模型对象操作。

    Zds0001_Save_Input ds0001SaveInput = new Zds0001_Save_Input();
    wdContext.nodeZds0001_Save_Input().bind(ds0001SaveInput);

    IDS0001QueryBankHeadNode queryBankHeadNode = wdContext.nodeDS0001QueryBankHead();

    try {
        for (int i = 0; i < queryBankHeadNode.size(); i++) {
            queryBankHeadNode.setLeadSelection(i);
            Zbank_Head bankHead = new Zbank_Head();
            WDCopyService.copyCorresponding(queryBankHeadNode.currentDS0001QueryBankHeadElement(), bankHead);
            ds0001SaveInput.addIt_Bank_Head(bankHead);
        }

        wdContext.currentZds0001_Save_InputElement().modelObject().execute();
        wdContext.nodeDS0001SaveOutput().invalidate();
    } catch (Exception e) {
        reportException(method, e);
    } finally {
        wdContext.currentZds0001_Save_InputElement().modelObject().modelInstance().disconnectIfAlive();
    }
