python往mysql存入数据_Python操作mysql之插入数据

之前有写过一篇python查询mysql数据的文章，今天写通过python插入数据到mysql数据库。

相关mysql视频教程推荐：《mysql教程》

先建库，建表，建用户mysql> create database top_ten;

mysql> use top_ten

mysql> create table log (id int PRIMARY KEY AUTO_INCREMENT, ip char(20), url char(30), status int, total int) charset=utf8;

mysql> create user 'bob'@'10.200.42.52' identified by 'talent';

mysql> desc log;

+--------+-------------+------+-----+---------+----------------+

+--------+-------------+------+-----+---------+----------------+

| id | int(11) | NO | PRI | NULL | auto_increment |

| ip | char(20) | YES | | NULL | |

| url | char(30) | YES | | NULL | |

| status | int(11) | YES | | NULL | |

| total | int(11) | YES | | NULL | |

+--------+-------------+------+-----+---------+----------------+

mysql> grant all on top_ten.* to bob@localhost identified by 'talent';

mysql> flush privileges;

在python下插入语句做下测试>>> import MySQLdb

>>> db = MySQLdb.connect(host='localhost',user='bob',passwd='talent',db='top_ten',port=3306, charset='utf8')

>>> db.autocommit(True)

>>> cursor = db.cursor()

>>> sql = "insert into log(ip, url, status, total) values('1.1.1.1', 'http', '200', '66')"

>>> cursor.execute(sql)

>>> sql = "insert into log(ip, url, status, total) values('2.2.2.2', 'http', '200', '66')"

>>> cursor.execute(sql)

#只能查询一条结果

>>> cursor.execute('select * from log')

>>> cursor.fetchone()

(1L, u'1.1.1.1', u'http', 200L, 66L)

#查询所有数据，然后一条条获取结果

>>> cursor.execute('select * from log')

>>> cursor.fetchmany()

((1L, u'1.1.1.1', u'http', 200L, 66L),)

>>> cursor.fetchmany()

((2L, u'2.2.2.2', u'http', 200L, 66L),)

>>> cursor.fetchmany()

()

#查询所有数据，一个元组显示所有结果

>>> cursor.execute('select * from log')

>>> cursor.fetchall()

((1L, u'1.1.1.1', u'http', 200L, 66L), (2L, u'2.2.2.2', u'http', 200L, 66L))
