看見(jiàn)characterset全是gbk就算成功了。

在UTF8字符集的老數(shù)據(jù)庫(kù)中,創(chuàng)建中文支持表腳本如下,對(duì)字段加上字符集說(shuō)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 寫(xiě)GB2312 和gbk都可以,gbk優(yōu)于gb2312。

對(duì)于新創(chuàng)建的數(shù)據(jù)庫(kù)加個(gè)默認(rèn)字符集聲明GBK,就不用建表時(shí)候每個(gè)字段聲明了,這樣看起來(lái)簡(jiǎn)單流暢,沒(méi)有特殊的痕跡,建議多采用這種方法。

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：如果這些腳本用bin/MySQL命令行是輸入不了,可以用MySQL query Browser,或者編程執(zhí)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)
---------------------------------------------

最后修改啟動(dòng)文件/etc/rc.d/rc.mysqld，改路徑/app/mysql/bin/mysqld_safe，改路徑/app/mysql/var/web.pid/app/mysql/bin/mysqld_safe 后面加入 --user=root --default-character-set=gbk。
