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。
