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;+--------+-------------+------+-----+---------+----------------+| Field | Type | Null | Key | Default | Extra |+--------+-------------+------+-----+---------+----------------+| 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)1L >>> sql = "insert into log(ip, url, status, total) values('2.2.2.2', 'http', '200', '66')">>> cursor.execute(sql)1L #只能查询一条结果>>> cursor.execute('select * from log')1L>>> 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')2L>>> 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')2L>>> cursor.fetchall()((1L, u'1.1.1.1', u'http', 200L, 66L), (2L, u'2.2.2.2', u'http', 200L, 66L))
插入脚本
[root@python ~]# mysql_insert.py#!/usr/bin/env python# -*- coding: utf-8 -*-'''Date:2017-03-28Author:Bob''' import MySQLdb def mysql_insert(): #Open the database connection db = MySQLdb.connect(host='localhost',user='bob',passwd='talent',db='top_ten',port=3306, charset='utf8') #Automatic submission db.autocommit(True) #Gets the operation cursor cursor = db.cursor() with open('access_log-20170217', 'r') as f: res = {} #Get ip, url, status for line in f.readlines(): line = line.split(' ') ip = line[0] url = line[6] status = line[8] #print ip, url, status #ip, url, status as key, each time plus 1 res[(ip, url, status)] = res.get((ip, url, status),0)+1 #Generate a list res_list = [(k[0],k[1],k[2],v) for k,v in res.items()] # Print the top ten lines #for k in sorted(res_list,key=lambda x:x[3],reverse=True)[:10]: #print k #SQL statement inserted for i in res_list: #print i sql = "insert into log(ip, url, status, total) values('%s', '%s', '%s', '%s')" %(i[0], i[1], i[2], i[3]) try: #Execute the SQL statement cursor.execute(sql) except Exception as e: print "Error: ", e #Close the cursor cursor.close() #Close the database connection db.close() if __name__ == '__main__': mysql_insert()
