Syntax

CREATE [OR REPLACE] {DATABASE | SCHEMA} [IF NOT EXISTS] db_name
    [create_specification] ...

create_specification:
    [DEFAULT] CHARACTER SET [=] charset_name
  | [DEFAULT] COLLATE [=] collation_name

Description

CREATE DATABASE creates a database with the given name. To use this statement, you need the CREATE privilege for the database. CREATE SCHEMA is a synonym for CREATE DATABASE. If the IF NOT EXISTS clause is used, a warning will be returned if the database already exists, rather than an error.

OR REPLACE

MariaDB starting with 10.1.3

The OR REPLACE clause was added in MariaDB 10.1.3

If the optional OR REPLACE clause is used, it acts as a shortcut for:

DROP DATABASE IF EXISTS db_name;
CREATE DATABASE db_name ...;

IF NOT EXISTS

When the IF NOT EXISTS clause is used, MariaDB will return a warning instead of an error if the specified database already exists.

Examples

CREATE DATABASE db1;
Query OK, 1 row affected (0.18 sec)

CREATE DATABASE db1;
ERROR 1007 (HY000): Can't create database 'db1'; database exists

CREATE DATABASE IF NOT EXISTS db1;
Query OK, 1 row affected, 1 warning (0.01 sec)

SHOW WARNINGS;
