mysql建立utf-8字符集數據庫

CREATE DATABASE db_name DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;

CREATE DATABASE 的語法：

CREATE {DATABASE | SCHEMA} [IF NOT EXISTS] db_name
[create_specification [, create_specification] ...]

create_specification:
[DEFAULT] CHARACTER SET charset_name
| [DEFAULT] COLLATE collation_name

 

更改數據庫的字符編碼

ALTER DATABASE db_name DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci
