    ReQL command: dbCreate

    Command syntax

    r.dbCreate(dbName) → object


    Create a database. A RethinkDB database is a collection of tables, similar to relational databases.

    If successful, the command returns an object with two fields:

    • dbs_created: always 1.
    • config_changes: a list containing one object with two fields, old_val and new_val:
      • old_val: always null.
      • new_val: the database’s new config value.

    If a database with the same name already exists, the command throws ReqlRuntimeError.

    Note: Only alphanumeric characters and underscores are valid for the database name.

    Example: Create a database named ‘superheroes’.



        "config_changes": [
                "new_val": {
                    "id": "e4689cfc-e903-4532-a0e6-2d6797a43f07",
                    "name": "superheroes"
                "old_val": null
        "dbs_created": 1
