db.collection.renameCollection(target, dropTarget)

Important

mongo Shell Method

This page documents a mongo method. This is not the documentation for database commands or language-specific drivers, such as Node.js. To use the database command, see the renameCollection command.

For MongoDB API drivers, refer to the language-specific MongoDB driver documentation.

Renames a collection. Provides a wrapper for the renameCollection database command.

Parameter	Type	Description
`target`	string	The new name of the collection. Enclose the string in quotes. See Naming Restrictions.
`dropTarget`	boolean	Optional. If `true`, `mongod` drops the `target` of `renameCollection` prior to renaming the collection. The default value is `false`.

Behavior

The db.collection.renameCollection() method operates within a collection by changing the metadata associated with a given collection.

Refer to the documentation renameCollection for additional warnings and messages.

Warning

The db.collection.renameCollection() method and renameCollection command will invalidate open cursors which interrupts queries that are currently returning data.

For Change Streams, the db.collection.renameCollection() method and renameCollection command create an invalidate for any existing Change Streams opened on the source or target collection.

The method has the following limitations:
- db.collection.renameCollection() cannot move a collection between databases. Use renameCollection for these rename operations.
- db.collection.renameCollection() is not supported on sharded collections.
- You cannot rename views.

Resource Locking

Changed in version 4.2.

renameCollection() obtains an exclusive lock on the source and target collections for the duration of the operation. All subsequent operations on the collections must wait until renameCollection() completes. Prior to MongoDB 4.2, renaming a collection within the same database with renameCollection required obtaining an exclusive database lock.

Interaction with `mongodump`

A mongodump started with --oplog fails if a client issues db.collection.renameCollection() during the dump process. See mongodump.--oplog for more information.

Example

Call the db.collection.renameCollection() method on a collection object. For example:

db.rrecord.renameCollection("record")

This operation will rename the rrecord collection to record. If the target name (i.e. record) is the name of an existing collection, then the operation will fail.
