ALTER DATABASE

ALTER DATABASE is used to specify or modify the default character set and collation of the current database. ALTER SCHEMA has the same effect as ALTER DATABASE.

Examples

ALTER {DATABASE | SCHEMA} [db_name]
    alter_specification ...
alter_specification:
    [DEFAULT] CHARACTER SET [=] charset_name
  | [DEFAULT] COLLATE [=] collation_name

The alter_specification option specifies the CHARACTER SET and COLLATE of a specified database. Currently, TiDB only supports some character sets and collations. See Character Set Support for details.
