使用mysql进行学习

1.样例表

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

2.MySQL安装

(1)下载

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

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)

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。

PS：直接用mysqld install安装会出现错误。

安装参考：http://blog.csdn.net/u013067166/article/details/49951577

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/

点击安装：

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

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。

(1)表的创建

1)新建schme，设置名字为tysql

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：

被选中：

右击选择send to SQL editor----create Statement，将create.txt中的代码粘贴到其中。

-- Create Customers table

-- ----------------------

CREATE TABLE Customers

(

cust_id char(10) NOT NULL ,

cust_name char(50) NOT NULL ,

cust_address char(50) NULL ,

cust_city char(50) NULL ,

cust_state char(5) NULL ,

cust_contact char(50) NULL ,

cust_email char(255) NULL

);

-- -----------------------

-- Create OrderItems table

-- -----------------------

CREATE TABLE OrderItems

(

order_num int NOT NULL ,

order_item int NOT NULL ,

prod_id char(10) NOT NULL ,

quantity int NOT NULL ,

item_price decimal(8,2) NOT NULL

);

-- -------------------

-- Create Orders table

-- -------------------

CREATE TABLE Orders

(

order_num int NOT NULL ,

order_date datetime NOT NULL ,

cust_id char(10) NOT NULL

);

-- ---------------------

-- Create Products table

-- ---------------------

CREATE TABLE Products

(

prod_id char(10) NOT NULL ,

vend_id char(10) NOT NULL ,

prod_name char(255) NOT NULL ,

prod_price decimal(8,2) NOT NULL ,

prod_desc text NULL

);

-- --------------------

-- Create Vendors table

-- --------------------

CREATE TABLE Vendors

(

vend_id char(10) NOT NULL ,

vend_name char(50) NOT NULL ,

vend_address char(50) NULL ,

vend_city char(50) NULL ,

vend_state char(5) NULL ,

vend_zip char(10) NULL ,

vend_country char(50) NULL

);

-- -------------------

-- Define primary keys

-- -------------------

ALTER TABLE Customers ADD PRIMARY KEY (cust_id);

ALTER TABLE OrderItems ADD PRIMARY KEY (order_num, order_item);

ALTER TABLE Orders ADD PRIMARY KEY (order_num);

ALTER TABLE Products ADD PRIMARY KEY (prod_id);

ALTER TABLE Vendors ADD PRIMARY KEY (vend_id);

-- -------------------

-- Define foreign keys

-- -------------------

ALTER TABLE OrderItems ADD CONSTRAINT FK_OrderItems_Orders FOREIGN KEY (order_num) REFERENCES Orders (order_num);

ALTER TABLE OrderItems ADD CONSTRAINT FK_OrderItems_Products FOREIGN KEY (prod_id) REFERENCES Products (prod_id);

ALTER TABLE Orders ADD CONSTRAINT FK_Orders_Customers FOREIGN KEY (cust_id) REFERENCES Customers (cust_id);

ALTER TABLE Products ADD CONSTRAINT FK_Products_Vendors FOREIGN KEY (vend_id) REFERENCES Vendors (vend_id);

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)

4)Schemas刷新一下，可看到有5个新建的table。

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。
