Python操作mysql之插入数据
短信预约 -IT技能 免费直播动态提醒
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。
1.先建库,建表,建用户
mysql> CREATE DATABASE tda DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
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;
2.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))
3.插入脚本
[root@python ~]# cat mysql_insert.py
#!/usr/bin/env python
# -*- coding: utf-8 -*-
'''

'''
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.iteritems()]
# 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
#Commit
db.commit()
#Close the cursor
cursor.close()
#Close the database connection
db.close()
if __name__ == '__main__':
mysql_insert()
4.执行脚本
[root@python ~]# python mysql_insert.py
5.查询验证
mysql> select * from log;
