最近安装了mac osx lion系统,然后安装了mysql5.5.16版本的数据库进行开发,但是大家都知道,mysql的默认编码是latin1,如果存储中文的话就会出现乱码,然后就狂google这个问题,但是一直都没有解决,网上大部分的回答都是如下:
1.拷贝/usr/local/mysql/support-files下的任意一个*.cnf文件到/etc/my.cnf;
2.在my.cnf文件的[mysqld]和[client]后面添加一句default-character-set=utf8(或者是default_character_set=utf8);
3.保存退出;
4.重新启动mysql服务器就可以。
可是我试过好多次,这样修改之后,mysql服务根本就启动不了。
偶然的机会,我发现了一个关于在linux下配置mysql的编码问题的方法,抱着试试看的态度,我进行了修改,发现真的可以用,因此发这篇博文希望装mac的朋友不用再走弯路了。配置方法如下:
1.拷贝/usr/local/mysql/support-files下的任意一个*.cnf文件到/etc/my.cnf;
2.在my.cnf文件的[client]后面添加一句default-character-set=utf8( 不是default_character_set=utf8[i][/i],这个配置我没有试过,不知道能不能成功),关键在这里的配置,在[mysqld]后面添加如下三句:
default-storage-engine=INNODB
character-set-server=utf8
collation-server=utf8_general_ci;
3.保存退出;
4.重新启动mysql服务器就可以。
然后再就入mysql数据库查看编码发现改成了utf8了。
下面是我重启mysql服务器进入mysql数据库查出来的结果:

至此,这个困扰多日的问题终于解决了。
附修改好的my.cnf文件内容,不知道为什么附件我上传不了,就把代码贴出来吧:

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索引优化器工作原理的相关内容,其中包括了MySQL Server的组成,MySQL优化器选择索引额原理以及SQL成本分析,最后通过 select 查询总结整个查询过程,下面一起来看一下,希望对大家有帮助。

sybase是基于客户/服务器体系结构的数据库,是一个开放的、高性能的、可编程的数据库,可使用事件驱动的触发器、多线索化等来提高性能。

数据库系统由4个部分构成:1、数据库,是指长期存储在计算机内的,有组织,可共享的数据的集合;2、硬件,是指构成计算机系统的各种物理设备,包括存储所需的外部设备;3、软件,包括操作系统、数据库管理系统及应用程序;4、人员,包括系统分析员和数据库设计人员、应用程序员(负责编写使用数据库的应用程序)、最终用户(利用接口或查询语言访问数据库)、数据库管理员(负责数据库的总体信息控制)。

visual foxpro数据库文件是管理数据库对象的系统文件。在VFP中,用户数据是存放在“.DBF”表文件中;VFP的数据库文件(“.DBC”)中不存放用户数据,它只起将属于某一数据库的 数据库表与视图、连接、存储过程等关联起来的作用。

microsoft sql server是Microsoft公司推出的关系型数据库管理系统,是一个全面的数据库平台,使用集成的商业智能(BI)工具提供了企业级的数据管理,具有使用方便可伸缩性好与相关软件集成程度高等优点。SQL Server数据库引擎为关系型数据和结构化数据提供了更安全可靠的存储功能,使用户可以构建和管理用于业务的高可用和高性能的数据应用程序。

结构层次是“数据库→数据表→记录→字段”;字段构成记录,记录构成数据表,数据表构成了数据库。数据库是一个完整的数据的记录的整体,一个数据库包含0到N个表,一个表包含0到N个字段,记录是表中的行。

数据库的“完整性”是指数据的正确性和相容性。完整性是指数据库中数据在逻辑上的一致性、正确性、有效性和相容性。完整性对于数据库系统的重要性:1、数据库完整性约束能够防止合法用户使用数据库时向数据库中添加不合语义的数据;2、合理的数据库完整性设计,能够同时兼顾数据库的完整性和系统的效能;3、完善的数据库完整性有助于尽早发现应用软件的错误。

mysql查询为什么会慢,关于这个问题,在实际开发经常会遇到,而面试中,也是个高频题。遇到这种问题,我们一般也会想到是因为索引。那除开索引之外,还有哪些因素会导致数据库查询变慢呢?
