ALTER DATABASE Syntax
ALTER DATABASE db_name alter_specification [, alter_specification] ....
alter_specification:
[DEFAULT] CHARACTER SET charset_name
| [DEFAULT] COLLATE collation_name
|
ALTER DATABASE allows you to change the overall characteristics of
a database.
The CHARACTER SET clause changes the database character set.
The COLLATE clause changes the database collation.
Database characteristics are stored in the `db.opt' file in the database directory.
To use ALTER DATABASE, you need the ALTER privilege on the
database.
ALTER DATABASE was added in MySQL 4.1.1.
