Definition¶

db.collection.renameCollection(target, dropTarget)¶

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.
`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.

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.

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.
