mysql用sql语句创建表和数据 设置字符编码为utf-8

简而言之

CREATE DATABASE xx CHARACTER SET utf8 COLLATE utf8_general_ci;
USE xx;
CREATE TABLE a1(qid VARCHAR(10),qname VARCHAR(10) CHARACTER SET utf8 COLLATE utf8_general_ci,qall VARCHAR(500) CHARACTER SET utf8 COLLATE utf8_general_ci,inge VARCHAR(100) CHARACTER SET utf8 COLLATE utf8_general_ci,outge VARCHAR(100) CHARACTER SET utf8 COLLATE utf8_general_ci,rate INT(1));
CREATE TABLE a2(qid VARCHAR(10) ,total INT(5) DEFAULT 0,corret INT(5) DEFAULT 0);
CREATE TABLE a3(qid VARCHAR(10),stdin VARCHAR(100) CHARACTER SET utf8 COLLATE utf8_general_ci,stdout VARCHAR(100) CHARACTER SET utf8 COLLATE utf8_general_ci,nn INT(5));

在数据库后 + 数据表的相应段 最后加上

CHARACTER SET utf8 COLLATE utf8_general_ci

即可

与网页交互的时候，需要设置网页的编码为utf-8，request交互的字符编码也为 utf-8

1.设置.jsp，html等的编码，并在servlet的service方法开头加上req. setCharacterEncoding(“UTF-8”);**

2.设置jdbc连接的编码jdbc:mysql://localhost:3306/dbname?characterEncoding=utf-8**

3.设置浏览器的编码，编程IDE的编码**
