Server characterset: gbk Db characterset: gbk Client characterset: gbk Conn. characterset: gbk .... 看见characterset全是gbk就算成功了。 在UTF8字符集的老数据库中,创建中文支持表脚本如下,对字段加上字符集说明: CREATE TABLE `test`.`cn` ( `zh` CHAR(10) CHARACTER SET gb2312 COLLATE gb2312_chinese_ci NOT NULL, `中文` INT(11) NOT NULL ) ENGINE = MYISAM; 注:CHARACTER SET 写GB2312 和gbk都可以,gbk优于gb2312。 对于新创建的数据库加个默认字符集声明GBK,就不用建表时候每个字段声明了,这样看起来简单流畅,没有特殊的痕迹,建议多采用这种方法。 mysql> CREATE DATABASE dbCN DEFAULT CHARACTER SET gbk COLLATE gbk_chinese_ci; CREATE TABLE `dbCN`.`cn` ( `zh` CHAR(10) NOT NULL, `中文` INT(11) NOT NULL ) ENGINE = MYISAM; mysql> insert into cn values("真的?",1); 注:如果这些脚本用bin/MySQL命令行是输入不了,可以用MySQL query Browser,或者编程执行。 ---------------------------------------------- shell> bin/mysql -u root --default-character-set=gbk -p mysql>use test mysql> select * from cn; -------- ------ | zh | 中文 | -------- ------ | 真的?| 1 | -------- ------ 1 row in set (0.00 sec) --------------------------------------------- 最后修改启动文件/etc/rc.d/rc.mysqld,改路径/app/mysql/bin/mysqld_safe,改路径/app/mysql/var/web.pid/app/mysql/bin/mysqld_safe 后面加入 --user=root --default-character-set=gbk。
