通过ObjectID获取MongoDB集合 [英] Get MongoDB collection by ObjectID

问题描述

MongoDB ID对于单个数据库集群而言是唯一的.是否可以获取使用特定ObjectID的集合?

MongoDB IDs are unique for a single db cluster. Is it possible to get the collection a specific ObjectID is used in?

我有一个ObjectID的十六进制表示，需要知道具有该ID的文档所在的集合.可能吗?

I have the hex representation of an ObjectID and need to know the collection the document with this ID is in. Possible?

推荐答案

这不是本机功能，但可以通过遍历所有集合(db.getCollectionNames())并调用find({_id: <yourid>})查询来实现.显然，这将是一个非常缓慢的操作，因此更改模式或使用ObjectId以外的其他内容作为_id值可能是您的前进之路.

It's is not a native feature but it is possible by iterating over all collections (db.getCollectionNames()) and invoking a find({_id: <yourid>}) query. Obviously this will be a very slow operation so a schema change or using something other than ObjectId as your _id value is probably the way forward for you.
