13.1.12 CREATE DATABASE Syntax

CREATE {DATABASE | SCHEMA} [IF NOT EXISTS] db_name
[create_specification] ...
create_specification:
[DEFAULT] CHARACTER SET [=] charset_name
| [DEFAULT] COLLATE [=] collation_name
| DEFAULT ENCRYPTION [=] {'Y' | 'N'}

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.

An error occurs if the database exists and you did not specify IF NOT EXISTS.

CREATE DATABASE is not permitted within a session that has an active LOCK TABLES statement.

create_specification options specify database characteristics. Database characteristics are stored in the data dictionary.

The CHARACTER SET clause specifies the default database character set. The COLLATE clause specifies the default database collation. Chapter 10, Character Sets, Collations, Unicode, discusses character set and collation names.
The DEFAULT ENCRYPTION clause, introduced in MySQL 8.0.16, defines the default database encryption, which is inherited by tables created in the database. If the DEFAULT ENCRYPTION clause is not specified, the default_table_encryption setting defines the default database encryption. If the table_encryption_privilege_check variable is enabled, the TABLE_ENCRYPTION_ADMIN privilege is required to specify a default encryption setting that differs from the default_table_encryption setting. For more information, see Defining an Encryption Default for Schemas and General Tablespaces.

A database in MySQL is implemented as a directory containing files that correspond to tables in the database. Because there are no tables in a database when it is initially created, the CREATE DATABASE statement creates only a directory under the MySQL data directory. Rules for permissible database names are given in Section 9.2, “Schema Object Names”. If a database name contains special characters, the name for the database directory contains encoded versions of those characters as described in Section 9.2.3, “Mapping of Identifiers to File Names”.

Creating a database directory by manually creating a directory under the data directory (for example, with mkdir) is unsupported in MySQL 8.0.

You can also use the mysqladmin program to create databases. See Section 4.5.2, “mysqladmin — Client for Administering a MySQL Server”.
