mysq gbk写入,utf-8提取
我的mysql数据库编辑为utf-8,里面的数据都是用gbk写入的。。因为通常提取的时候也是设置gbk,所以虽然数据库里面是乱码,但提取出来却是正常的。。。现在必须在utf-8的环境下提取这些数据。。请教大神,该如何处理才能正常显示????
分少勿怪。。
------解决方案--------------------
按道理来说取时用gbk显示转成utf-8了。具体还得测试。
最好是搞统一了。
------解决方案--------------------
查询数据前先 " set names utf8 " 即可在utf-8环境中正常显示
------解决方案--------------------
mysql_query('ste names utf8');
------解决方案--------------------
mysql_query('ste names utf8');
设置编码
------解决方案--------------------
iconv
------解决方案--------------------
字段类型为utf8?
以前有没有用set names gbk?
用length(....)测一下汉字长度,如果正常的话用set name utf8即可
否则,export后改文件开头处的编码再导入
------解决方案--------------------

本篇文章给大家带来了关于mysql的相关知识,其中主要介绍了关于架构原理的相关内容,MySQL Server架构自顶向下大致可以分网络连接层、服务层、存储引擎层和系统文件层,下面一起来看一下,希望对大家有帮助。

mysql的msi与zip版本的区别:1、zip包含的安装程序是一种主动安装,而msi包含的是被installer所用的安装文件以提交请求的方式安装;2、zip是一种数据压缩和文档存储的文件格式,msi是微软格式的安装包。

Go语言编码解析:UTF-8与GBK对比在Go语言中,处理字符串编码是常见的任务之一。其中,UTF-8和GBK是两种常用的字符编码方式。本文将对UTF-8和GBK进行详细对比,探讨它们的区别和使用方法,并附上具体的代码示例。一、UTF-8与GBK的简介UTF-8:UTF-8是一种可变长度的Unicode编码方式,它可以表示世界上几乎所有语言的字符。UTF-8

在mysql中,可以利用char()和REPLACE()函数来替换换行符;REPLACE()函数可以用新字符串替换列中的换行符,而换行符可使用“char(13)”来表示,语法为“replace(字段名,char(13),'新字符串') ”。

转换方法:1、利用cast函数,语法“select * from 表名 order by cast(字段名 as SIGNED)”;2、利用“select * from 表名 order by CONVERT(字段名,SIGNED)”语句。

本篇文章给大家带来了关于mysql的相关知识,其中主要介绍了关于MySQL复制技术的相关问题,包括了异步复制、半同步复制等等内容,下面一起来看一下,希望对大家有帮助。

在mysql中,可以利用REGEXP运算符判断数据是否是数字类型,语法为“String REGEXP '[^0-9.]'”;该运算符是正则表达式的缩写,若数据字符中含有数字时,返回的结果是true,反之返回的结果是false。

在mysql中,是否需要commit取决于存储引擎:1、若是不支持事务的存储引擎,如myisam,则不需要使用commit;2、若是支持事务的存储引擎,如innodb,则需要知道事务是否自动提交,因此需要使用commit。
