CREATE DATABASE

Create a database

• Syntax

  CREATE DATABASE [IF NOT EXISTS] db_name

  db_name: the name of the database. The database name can be up to 64 characters in length, and can contain letters, digits, and underscores (_). It must start with a lowercase letter and cannot contain consecutive underscores (_).

You can execute the USE db_name statement to use a database after it is created.
