1.Download Connector/Python：mysql-connector-python-2.1.3-py2.7-win32
Mysql：mysql-installer-community-5.5.48.0
Python：python-2.7.10
2.安装好Python，Mysql
Connector/Python: http://dev.mysql.com/doc/connector-python/en/connector-python-installation.html
Python3不再支持mysqldb,
取而代之的是：import pymysql
Python MySQL 官方包：mysql-connector-python
3.测试代码
Mysql:查看所有用户 select * from mysql.user;
show databases ; ----------查看全部数据库
use test; --使用数据库
# -*- coding: utf8 -*-
import mysql.connector
conn=mysql.connector.connect(
host=‘127.0.0.1‘,
port=3306,
user=‘root‘,
passwd=‘[email protected]‘,
db=‘test‘,
)
cursor = conn.cursor()
cursor.execute ("SELECT VERSION()")
row = cursor.fetchone ()
print "server version:", row[0]
cursor.close()
conn.close()
4.管理数据库
DbVisualizer 8.0.8管理
CREATE TABLE 表名 (字段名 VARCHAR(20), 字段名 CHAR(1));
create table pet(
name varchar(20), #名字
owner varchar(20),#主人
species varchar(20), #种类
sex char(1), #性别
birth date, #出生日期
death date,#死亡日期)
show tables;
select * from tb;
要建立外键关系，首先要保证用来建立外键关系的列具有唯一性，即具有 UNIQUE 约束
通常是某表的主键作为另外一个表的外键
mysql版本和驱动版本不匹配

Msql终端添加：
alter table student add constraint score_student_fk1 foreign key (ScoreID) references score(ScoreID)
alter table student add constraint score_student_fk1 foreign key (ScoreID) references score(ScoreID)
