   这几天基于Heritrix写了一个爬虫,用到mysql,在导入导出数据时,遇到一些乱码问题,好不容易解决了,记录一下,以备查看。

  一、导出数据。

  先说明一下自己的环境:Mac OS X 10.8.3, MySQL Community Server 5.6.10, MySQL Workbench 5.2.47。

  我想把本机数据库内的数据迁移到另一台机器上,于是使用Workbench中自带的import/export功能,其实就是调用mysqldump。不幸的是,出现了版本不一致的错误。

  错误没治了,最终找到解决方案,可以指定mysql的mysqldump,路径为:/usr/local/mysql/bin/mysqldump,这样是把数据导出为sql语句的insert语句。

  由于需要是把数据导出为excel,所以通过mysql控制台使用select语句把数据导出到excel文件中。

  下面先介绍怎么导出为excel文件,然后介绍怎么导出为insert语句。

  1、通过终端操作。

  1 cd /usr/local/mysql/bin/

  2、到达bin目录后,可以ls -l命令看看当前目录有哪些程序可以用,这里先用mysql,命令格式为:

  mysql -h主机IP -u用户名 -p密码

  如:

  1 ./mysql -hlocalhost -uroot -p123456

  注意前面加的"./"。

  这时就进入mysql命令控制台,终端上显示为:

  3、然后通过show databases命令查看当前的所有数据库,,使用use命令选择进入某个数据库,注意每个命令都要以英文分号“;”结束。

  4、使用sql语句导出需要的数据,sql语句不限于单个表的查询。由于我的数据库编码是utf8格式,而office默认的编码则是gb2312,所以当某个字段中包含中文时,导出到excel后,中文内容是会乱码的,此时需要convert转换编码,具体使用方式:

  我试着把文件保存到桌面,但始终提示没有权限,应该是和用户有关吧,无视了。当使用“./”这个路径保存时,实际是保存到了/usr/local/mysql/data下面。打开看看,哟西,不乱码了。

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.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
