mongodb - 如何硬编码 mongoexport 字段数据

Question

我的 MongoExport 将提取三个字段——字段名、姓氏、电子邮件、城市

输出：

firstname,lastname,email,city
"Fn1","Ln1","abc@abc.com","chicago"
"Fn2","Ln2","xyz@xyz.com","atlanta"

我希望隐藏电子邮件，所以我需要一个硬编码值“EMAIL”而不是实际的电子邮件。

"Fn1","Ln1","EMAIL","chicago"
"Fn2","Ln2","EMAIL","atlanta"

这可以在mongo导出中完成吗？
