回答1:

1、 mysql安装好后,在mysql的安装目录中有个bin目录,里面有很多客户端软件,如果是mysql的客户端,找到mysql.exe,这个是用于操作数据库的系统客户端软件。

2、 客户端选择:一般情况下,我们在学习的时候会通过使用Windows下的控制台进行访问,即win + R 同时按住打开运行,输入cmd命令进入控制台,然后进入到mysql的bin目录(具体可以看一下Windows下控制器切换路径(百度经验));或者在开发的时候通常会使用一些集成工具,如Navicat之类。

3、 数据库操作步骤:学习的时候客户端和服务端是同时安装的,都在一台电脑上,但是要理解,mysql的客户端和服务端通常不会在一台机器上的(服务器在机房,客户端就在个人电脑上),因此是需要进行一些步骤操作的。(下面以windows下的控制台为例)

① 连接认证:mysql/mysql.exe -h主机地址 -P端口 -u用户名 -p密码,其中h可以是ip地址也可以是主机名如-hlocalhost/-h127.0.0.1,本地可以省略;-P(大写P)是端口,一般mysql是3306,默认可以省略;-u是用户名,如果没有匿名账号,必填;-p(小写p)是密码,一般必填,最好是输入-p后先回车,后输入密码(密文输入密码,更安全)

② 发送SQL指令,SQL(【百科】结构化查询语言Structured Query Language结构化查询语言)是mysql能识别的操作指令,这块如果想深入学习理解可以参照MySQL的API文档或者参考黑马程序员下的6天玩转MySQL,一般情况下分为几大类:

DDL:Data Definition Language,数据定义语言,定义结构。如创建数据库:create database `test` charset utf8;

DML:Data Manipulation Language,数据操作语言,进行数据操作。如增删改查指令:insert into table values()/delete from table where condition/update table set key = value/select * from table

DCL:Data Controller Language,数据控制语言,进行权限管理。如给用户授权:grant seletet on *.* to 'root'@localhost

③ 解析:一般情况下客户端会自动解析MySQL服务器执行返回的结果不需要我们进行额外操作,但是如果是其他编程语言需要使用MySQL执行的结果,那么还需要额外的解析(参照黑马程序员6天玩转MySQL中的PHP操作mysql)

④ 断开连接:数据库用完之后,要养成主动断开的习惯(被动也可以,但是如果被动没有断开,那么就会“占线”),mysql的客户端可以使用\q | quit | exit,任意一个退出

回答2:

  1. 一般都用第三方管理软件,比如MySQL Tools for 5.0

  2. 要是想在控制台连接数据库的话,设置一下环境变量就随便打开个控制台就能访问了。

  3. 将MySQL安装目录的bin目录设置到环境变量Path中,比如:"C:\Program Files\MySQL\MySQL Server 5.0\bin" 

  4. 然后在控制台中按格式输入信息就可以对数据库进行操作了。

    格式:mysql --user=用户名 --password=密码 [数据库名]

回答3:

点开始按钮 看有没有mysql work bench 有的话,就能可视化
没有的话,win建+r建同时按住 输入cmd 回车
输入 mysql -u root -p密码 回车 就进去了

回答5:

有很多Mysql的可视化工具啊。我最常用的是sqlyong。还有HeidiSQL这个也挺好用啊。安装完后,点击快捷图标,就会打开进入的界面,一般第一次使用都会让你输入访问的地址,端口,用户名和密码的。地址如果是本地就是localhost,如果是其他机器,就是IP地址。
