ReQL command: db_create

Command syntax

r.db_create(db_name) → 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 nil.
    • 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, hyphens 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 => nil
    :dbs_created => 1
