如何在批处理

Question

我坚持创建一个具有两个任务的批处理作业 - 一个用于从登台表获取数据，另一个用于将登台表中的数据导出到平面文件。

第一个任务要求我调用DMFStagingWriter class并且它是＆＃39;工作正常，我的批处理可以将数据填充到临时表中。但是，当我尝试添加一些代码来完成dmfStagingToSourceFileWriter class调用的第二个任务时，我暂时无法完成。 我的代码中有一条由"// Write from Staging table to file"注释启动的部分，我很难编写正确的代码，以帮助我将数据从登台表导出到文件

我错过了什么？

谢谢。
