之前有寫過(guò)一篇python查詢MySQL數(shù)據(jù)的文章，今天寫通過(guò)python插入數(shù)據(jù)到mysql數(shù)據(jù)庫(kù)。

專注于為中小企業(yè)提供成都做網(wǎng)站、網(wǎng)站建設(shè)服務(wù),電腦端+手機(jī)端+微信端的三站合一,更高效的管理,為中小企業(yè)河?xùn)|免費(fèi)做網(wǎng)站提供優(yōu)質(zhì)的服務(wù)。我們立足成都，凝聚了一批互聯(lián)網(wǎng)行業(yè)人才，有力地推動(dòng)了數(shù)千家企業(yè)的穩(wěn)健成長(zhǎng)，幫助中小企業(yè)通過(guò)網(wǎng)站建設(shè)實(shí)現(xiàn)規(guī)模擴(kuò)充和轉(zhuǎn)變。

1.先建庫(kù)，建表，建用戶

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下插入語(yǔ)句做下測(cè)試

>>>?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

#只能查詢一條結(jié)果
>>>?cursor.execute('select?*?from?log')
1L
>>>?cursor.fetchone()
(1L,?u'1.1.1.1',?u'http',?200L,?66L)


#查詢所有數(shù)據(jù)，然后一條條獲取結(jié)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()
()

#查詢所有數(shù)據(jù)，一個(gè)元組顯示所有結(jié)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.插入腳本

[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

????#?Print?the?top?ten?lines

????????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.執(zhí)行腳本

[root@python?~]#?python?mysql_insert.py

5.查詢驗(yàn)證
