前段时间公司服务器做平台迁移,需要将Linux下的MySQL数据库导出到Windows的服务器下。很自然的用了mysqldump指令导出了SQL文件,然后在Windows下进行了MySQL导入操作。导入结束后检查了表数量等等都没问题,于是很自然的以为导入工作顺利完成。

结果哪知道后来发现出来了乱码的问题,多次尝试mysqldump导出后导入都不行。于是,只能是编码的问题导致这样的情况了。

Linux系统安装的MySQL,默认的语言是latin1;而Windows下的MySQL在图形化界面安装过程中已经设置默认编码为UTF-8了。看来应该就是这样的问题了,编码问题害死人,经常乱码不说还折腾人

于是网上搜索了一圈,很简单的就解决了,记录解决步骤如下:

1、以Linux下的MySQL默认编码导出数据:

#mysqldump -u USERNAME -pPASSWORD –default-character-set=latin1 [DBname] > [filepath/filename.sql]

其中USERNAME为数据库用户名,一般为root。PASSWORD为密码,也可以不填写,只带上-p标记。最关键的就要数“–default-character-set=latin1”这部分了,一定要跟Linux系统下的编码设置一致。然后DBName为数据库名,后面就是导出的文件路径了。

2、在Windows下用NotePad++、UltraEdit之类的支持多编码格式的文本编辑器打开这个导出的SQL文件,看看有没有乱码。如果没有乱码的话,进行下面的操作。

找到:

CREATE TABLE `table` (
…略…
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

将其改为:

CREATE TABLE `table` (
…略…
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;

3、将改好的文件保存成UTF8格式,注意不要添加BOM信息,这样就得到一个UTF8的SQL文档了!

4、执行MySQL导入命令:

mysql -u USERNAME -pPASSWORD [DBname]

5、用phpMyAdmin检查下,现在终于不乱码了,问题解决!

MySQL: String Data Types and CollationsMySQL: String Data Types and CollationsMay 09, 2025 am 12:08 AM

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.
