You can use BTEQ or Fastexport if it is done on a server. Since you are mentioning Queryman, I think you are working on a desktop? If so, I don't think you will be able to export something as big as this to your desktop. Be aware that you have your limitations of memory on your desktop, which will be probable exceeded by an export of 3 million rows with 60 fields. Besides, such files are hardly useful except for exchanging it to other systems?
