The CREATE DATABASE statement creates a new CockroachDB database.
Required Privileges
Only the root user can create databases.
Synopsis
Parameters
| Parameter | Description |
|---|---|
IF NOT EXISTS |
Create a new database only if a database of the same name does not already exist; if one does exist, do not return an error. |
name |
The name of the database to create, which must be unique and follow these identifier rules. |
encoding |
The CREATE DATABASE statement accepts an optional ENCODING clause for compatibility with PostgreSQL, but UTF-8 is the only supported encoding. The aliases UTF8 and UNICODE are also accepted. Values should be enclosed in single quotes and are case-insensitive.Example: CREATE DATABASE bank ENCODING = 'UTF-8'. |
