怪事了,帮帮我吧,MySQL 4.1.18中不能写入“禤”这个字!!! to:ice_berg16(寻梦的稻草人) 没提示任何错误,提示操作成功,但就是写不进去。 解决方案 » 免费领取超大流量手机卡,每月29元包185G流量+100分钟通话, 中国电信官方发货 我估计是字符集的原因,这个字在gb2312中好像是没有的,但在gbk中是有的。但我不知道怎样来改变MySQL 4.1.18的默认的字符集。有谁知道怎样可以很方便的改变MySQL 4.1.18的默认的字符集? 修改mysql配置文件,如 my.ini[mysqld]basedir=D:/mysqldatadir=D:/mysql/data#设置默认字符集,如gbkdefault-character-set=gbk or you can use uft-8 to:loveflea(coolwind)不能设置:default-character-set=gbk,设置后mysql不能启动! to:zeroleonhart use uft-8 “禤”这个字变成了:“缎” mysql没提示错误你怎么可能写不进去?用mysql_error();输出错误看看,一般来说是字符集不同造成的你可以设置数据库或表为GBK编码即可 to : ice_berg16怎样设置数据库或表为GBK编码,请指教,谢谢! to : Gdj我试过了,就是因为这个字,后面所有的字都没有了。 执行show variables。把结果显示出来。 mysql> show variables;+---------------------------------+---------------------------------------+|

如果你以后还有可能用上别的字符集,可以同时把所有字符集装上--with-extra-charsets=all
没有别的办法了吗?例如,改一下mysql的配置行不行?重新编译太麻烦了,我们的服务器基本上是不能停的! :(
