  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 -*-
  '''
  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.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;
