Sample:创建数据库表 mysql>CREATE DATABASE IF NOT EXISTS my_db default charset utf8 COLLATE utf8_general_ci; #注意后面这句话 "COLLATE utf8_general_ci",大致意思是在排序时根据utf8变码格式来排序 #那么在这个数据库下创建的所有数据表的默认字符集都会是utf8了 mysql>create table my_table (name varchar(20) not null default '')type=myisam default charset utf8; #这句话就是创建一个表了,制定默认字符集为utf8 C++ sample code: 1. boost libary is required.
