以前、Python で mysql データをクエリすることについての記事を書きました。今日は、Python を介して mysql データベースにデータを挿入する方法について書きます。
推奨される関連する mysql ビデオ チュートリアル: "mysql チュートリアル"
まずデータベースを構築し、テーブルを作成し、ユーザーを作成します
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;
テストのために Python の下にステートメントを挿入します
>>> 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))
スクリプトを挿入します
[root@python ~]# mysql_insert.py #!/usr/bin/env python # -*- coding: utf-8 -*- ''' Date:2017-03-28 Author: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()
スクリプトを実行します
[root@python ~]# python mysql_insert.py
