How to rename the collection – MongoDB

In MongoDB, you can use the db.runCommand() method to rename a collection. The db.runCommand() method takes a document as its argument, and the document must contain the following props:

• renameCollection: The name of the collection to be renamed.
• to: The new name of the collection.

For example, to rename the collection your_database.your_table to your_database.your_new_table_name, you would use the following command:

db.runCommand({renameCollection: "your_database.your_table", to: "your_database.your_new_table_name"});

If the rename operation was successful, the db.runCommand() method will return a document with the status of the operation.

{
  ok: 1,
  '$clusterTime': {
    clusterTime: Timestamp({ t: 1689910863, i: 27 }),
    signature: {
      hash: Binary(Buffer.from("3f999f9155064aa974469f94304958eba5eef4b3", "hex"), 0),
      keyId: Long("7200478234696220854")
    }
  },
  operationTime: Timestamp({ t: 1689910863, i: 27 })
}

Here are some additional things to keep in mind when renaming a collection:

• You can only rename a collection that exists in the current database.
• You cannot rename a collection to a name that already exists in the database.
• If you rename a collection that is being used by a running application, the application may need to be restarted in order to see the changes.
