当你遇到这个mysql保存中文乱码问题的时候,期待找到mysql保存中文乱码的原因和解决办法这样一篇能解决问题的文章是多么激动人心。
   也许30%的程序员会选择自己百度,结果发现网友已经贴了很多类似mysql 中文乱码、php mysql 中文乱码、mysql5.5中文乱码、mysql 乱码、mysql乱码问题、mysql jsp 乱码、mysql jdbc 乱码、mysql 查询乱码、mysql 导入数据乱码等一系列问题,到底哪个是自己要找的能解决自己问题的呀?15%的程序员一看就懵了,剩下15%的程序员自己摸索或求教别人了。70%的程序员干脆不干了,干不动咱还是程序员,这种浪费生命的事情让别人干去把,呵呵。
 其实mysql的乱码问题,说复杂也非常地负责,说简单简单的不行!区别就在于明白mysql乱码的本质原因,本文就从这个角度目的让煞笔程序员都掌握如何处理这个乱码问题。  (1)网站本身的编码。这不多说了,自己看看设置对了没,比如我设置的GBK就检查下编码是不是GBK。(一般通过文件右击属性来看,或建立工程的时候来统一设置)
   (2)数据库连接字符串的编码。比如java中我连接mysql的相关语句如下: public static String driverName = "com.mysql.jdbc.Driver";
 public static String userName = "root";
 public static String userPasswd = "123456";
 public static String dbName = "myBook";
 public static String url = "jdbc:mysql://localhost/" + dbName + "?user="
 + userName + "&password=" + userPasswd
 + "&useUnicode=true&characterEncoding=GBK";。。。。。Class.forName(driverName).newInstance();
connection = (Connection) DriverManager.getConnection(url);如上面的代码中,加粗的就是我要说的部分,可以设置为你想要的字符串类型,这里设置的是GBK,这仅仅是java语言的示例,其他语言asp、php原理是一样的都有这样的数据库字符串链接关于字符集的配置,不会就查查手册或百度一下,这个很容易找到,如果百度还找不到,那360干他也对。
   (3)mysql的字符集设置。  这个是重点了,一般都是在这里搞错而出现了mysql乱码。  mysql编码设置可以分为三种设置:数据库的编码、表的编码、和字段的编码。  a、数据库的编码:  在sqlyog工具中操作把,右击数据库点击更改数据库,如图
  //
 设置就可以了,煞笔不煞笔,简单不简单。  b、表的编码:  mysql很扯淡的是,表级别也设置了编码,说说咋设置把 /
 右击要修改编码的表,点击更改表如上图,点了以后如下图: /
  点高级属性,表的字符编码设置很煞笔很简单,看到了把。记得修改完毕后,一定要点击Alter才行呀!这个按钮很容易被忽略,操蛋的sqlyog呀!  c、字段的编码:  mysql确实很扯淡,字段都有编码设置,还是上面的更改表,不过不点高级属性了。看图:
 /
坑爹的默认不显示,对就是在右下角呢!看到了把,把对号取消把,取消后你看到了下图:
 /
  终于看到了字段后面跟的字符编码设置,他奶奶的熊,终于都找全了。设置把。记得修改完毕后,一定要点击Alter才行呀!这个按钮很容易被忽略,操蛋的sqlyog呀!
  最后再出一个绝招把: SHOW CREATE TABLE 表名CREATE TABLE `wen` (
  `id` int(8) DEFAULT NULL,
  `bookid` int(8) DEFAULT NULL,
  `title` varchar(200) COLLATE gbk_bin DEFAULT NULL,
  `content` longtext COLLATE gbk_bin
) ENGINE=InnoDB DEFAULT CHARSET=gbk COLLATE=gbk_bin CHECKSUM=1 DELAY_KEY_WRITE=1 ROW_FORMAT=DYNAMIC

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
