# 导入MySQL驱动:
> import mysql.connector
# 注意把password设为你的root口令:
> conn = mysql.connector.connect(user='root', password='password', database='test', use_unicode=True)
> cursor = conn.cursor()
# 创建user表:
> cursor.execute('create table user (id varchar(20) primary key, name varchar(20))')
# 插入一行记录，注意MySQL的占位符是%s:
> cursor.execute('insert into user (id, name) values (%s, %s)', ['1', 'Michael'])
> cursor.rowcount
1
# 提交事务:
> conn.commit()
> cursor.close()
# 运行查询:
> cursor = conn.cursor()
> cursor.execute('select * from user where id = %s', '1')
> values = cursor.fetchall()
> values
[(u'1', u'Michael')]
# 关闭Cursor和Connection:
> cursor.close()
True
> conn.close()
