Warning:
As of April 12, 2019, CockroachDB v1.1 is no longer supported. For more details, refer to the Release Support Policy.

The CREATE DATABASE statement creates a new CockroachDB database.

Required Privileges

Only the root user can create databases.

Synopsis

CREATE DATABASE IF NOT EXISTS name WITH ENCODING = encoding

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'.

Example

Create a Database

> CREATE DATABASE bank;
> SHOW DATABASES;
+----------+
| Database |
+----------+
| bank     |
| system   |
+----------+

Create Fails (Name Already In Use)

> SHOW DATABASES;
+----------+
| Database |
+----------+
| bank     |
| system   |
+----------+
> CREATE DATABASE bank;
pq: database "bank" already exists
> SHOW DATABASES;
+----------+
| Database |
+----------+
| bank     |
| system   |
+----------+
> CREATE DATABASE IF NOT EXISTS bank;

SQL does not generate an error, but instead responds CREATE DATABASE even though a new database wasn't created.

> SHOW DATABASES;
+----------+
| Database |
+----------+
| bank     |
| system   |
+----------+
