使用MySQL进行学习

1.样例表

下载地址：http://www.forta.com/books/0672336073/

技术分享

2.MySQL安装

(1)下载

地址：http://dev.mysql.com/downloads/mysql/

技术分享

ZIP Archive版是免安装的，只要解压就行了，和安装版的没什么不同，将下载好的文件mysql-5.7.16-winx64.zip解压到D:\Program Files\SQL

打开D:\Program Files\SQL\mysql-5.7.16-winx64\bin目录下mysql.exe。出来一个黑窗口就没反应了。

(2)配置默认文件

在D:\Program Files\SQL\mysql-5.7.16-winx64\bin目录下，新建my.ini。复制下面的代码保存就ok了。

[mysql]

# 设置mysql客户端默认字符集

default-character-set=utf8

[mysqld]

#设置3306端口

port = 3306

# 设置mysql的安装目录

basedir=D:\Program Files\SQL\mysql-5.7.16-winx64

# 设置mysql数据库的数据的存放目录

datadir=D:\Program Files\SQL\mysql-5.7.16-winx64\data

# 允许最大连接数

max_connections=200

# 服务端使用的字符集默认为8比特编码的latin1字符集

character-set-server=utf8

# 创建新表时将使用的默认存储引擎

default-storage-engine=INNODB

.ini文件是window里面的配置文件。保存里面各种默认的数据。安装版的是在安装的时候让你自己选然后系统给你保存进来，zip archive则是自己写。

注意my.ini文件必须在\bin目录中。

(3)安装mysql服务

以管理员身份运行cmd，切换到D:\Program Files\SQL\mysql-5.7.16-winx64\bin目录。

输入：mysqld --defaults-file=my.ini --initialize-insecure并回车，无报错。

输入：mysqld install并回车。

输入 net start mysql 启动服务。(也可以手动开启)

技术分享

安装成功。

输入mysql -u root -p，输入密码，初始为空可直接回车，mysql可以使用了。

技术分享

PS：直接用mysqld install安装会出现错误。

3.MySQL Workbench

MySQL Workbench 是 MySQL AB 释放的可视数据库设计工具，是设计MySQL 数据库的专用工具。

下载地址：http://dev.mysql.com/downloads/workbench/

技术分享

点击安装：

技术分享

更改安装目录：D:\Program Files\MySQL\MySQL Workbench 6.3 CE\

技术分享

打开后界面：

4.建立数据库

双击Local instance MySQL（已经配置好了）以打开SQL编辑器。

技术分享

(1)表的创建

1)新建schme，设置名字为tysql

技术分享

点击保存。

2)现在可以在编辑器窗口中更改SQL类型，但必须首先确保选中了新创建的数据库。如果被选中，它的名称将以粗体显示在标题栏中。如果tysql未被选中，在左边窗口中双击tysql。

未被选中：

注意：必须将CREATE DATABASE `tysql` /*!40100 DEFAULT CHARACTER SET latin1 */;这行代码删除，否则执行会报错，提示tysql的database已经创建过了。

3)执行Query----Execute(All or selection)

技术分享

4)Schemas刷新一下，可看到有5个新建的table。

技术分享

创建成功，关闭SQL Statement窗口，保存为create.sql。

(2)表的填充

1)右击选择send to SQL editor----create Statement，粘贴populate.txt中的代码。
