ReQL command: db_create

Command syntax

r.db_create(db_name) → object

Description

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 None.
  • 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’.

r.db_create('superheroes').run(conn)

{
    "config_changes": [
        {
            "new_val": {
                "id": "e4689cfc-e903-4532-a0e6-2d6797a43f07",
                "name": "superheroes"
            },
            "old_val": None
        }
    ],
    "dbs_created": 1
}
