MongoDB query to rename a collection?

To rename a collection in MongoDB, use renameCollection(). Let us create a collection with documents −

> db.demo690.insertOne({_id:101,Name:"Sam"});
{ "acknowledged" : true, "insertedId" : 101 }
> db.demo690.insertOne({_id:102,Name:"Mike"});
{ "acknowledged" : true, "insertedId" : 102 }
> db.demo690.insertOne({_id:103,Name:"John"});
{ "acknowledged" : true, "insertedId" : 103 }

Display all documents from a collection with the help of find() method −

> db.demo690.find();

This will produce the following output −

{ "_id" : 101, "Name" : "Sam" }
{ "_id" : 102, "Name" : "Mike" }
{ "_id" : 103, "Name" : "John" }

Following is the query to rename collection −

> db.demo690.renameCollection("demo691");
{ "ok" : 1 }

Display all documents from a collection with the help of find() method −

> db.demo691.find();

This will produce the following output −

{ "_id" : 101, "Name" : "Sam" }
{ "_id" : 102, "Name" : "Mike" }
{ "_id" : 103, "Name" : "John" }
