mongodb怎么删除特定的文档

Question

> db.test.find()
{ "_id" : ObjectId("5c08e86cbfd9756856063341"), "name" : "xiaobin", "age" : 27, "gender" : "male" }
{ "_id" : ObjectId("5c09ddb5ca83e5589d6754ef"), "name" : "xiaojun", "age" : 30, "gender" : "male" }
{ "_id" : ObjectId("5c09e4fcca83e5589d6754f1"), "name" : "xiaobin" }

如何删除第三条记录，如果条件是{name:'xiaobin'}的话第一条也会被删除。

Answer 1

删除的条件是{_id:'5c09dde0ca83e5589d6754f1}
_id是mongoDB默认生成的主键，根据_id进行删除
