CREATE DATABASE
This statement creates a new database in TiDB. The MySQL terminology for 'database' most closely maps to a schema in the SQL standard.

Syntax
The CREATE DATABASE statement is used to create a database, and to specify the default properties of the database, such as the default character set and collation. CREATE SCHEMA is a synonym for CREATE DATABASE.
CREATE {DATABASE | SCHEMA} [IF NOT EXISTS] db_name
[create_specification] ...
create_specification:
[DEFAULT] CHARACTER SET [=] charset_name
| [DEFAULT] COLLATE [=] collation_name
If you create an existing database and does not specify IF NOT EXISTS, an error is displayed.
The create_specification option is used to specify the specific CHARACTER SET and COLLATE in the database. Currently, TiDB only supports some of the character sets and collations. For details, see Character Set Support.
