“How can I Rename a collection in MongoDB?”

Definition: “Rename or changes the name of an existing collection”.

Try the Video live example of the code shown in this page using Robomongo!

Syntax:-

{renameCollection: "Original_collection_name>", to: "<New_collection_name>", dropTarget: <true | false>}

What is “renameCollection”? It is the name of the original collection to rename.

What is “to”? It is the new name of the collection.

What is “dropTarget”? If dropTarget is “true”, mongod will drop the target of renameCollection before to renaming the collection. The default value is “false”.

Examples:-

db.Original_Coll_Name.renameCollection('new_Coll_Name');
//The “db.collection.renameCollection()” is not supported on sharded collections.

//OR

db.Original_Coll_Name.renameCollection('ifAlreadyExistColl', true);
