工具：mysql.connector和mysqldb，(pymysql據說也不錯，沒試過)
1.mysql.connector介紹(推薦)：
是mysql官方提供的python連線mysql資料庫的驅動程式
是純python實現的，由oracle維護
相較於mysqldb模組來說，其支援python3，而mysqldb目前只支援到python2.7版本
2.mysqldb介紹：
也就是mysql-python
3.demo
3.1 主函式
#!/usr/bin/python
#coding=utf-8
from mysqlconnectordemo import *
from mysqldbdemo import *
if __name__ == '__main__':
conf = '.format(err))
except mysql.connector.error as err:
if err.errno == errorcode.er_access_denied_error:
print("something is wrong with your user name or password")
elif err.errno == errorcode.er_bad_db_error:
print("database does not exist")
else:
print(err)
else:
conn.close()
def insert(self,conf,sql):
try:
conn = mysql.connector.connect(**conf)
print("conn success!")
cursor = conn.cursor()
try:
cursor.execute(sql)
conn.commit()
cursor.close()
except mysql.connector.error as err:
print('insert datas error!{}'.format(err))
except mysql.connector.error as err:
if err.errno == errorcode.er_access_denied_error:
print("something is wrong with your user name or password")
elif err.errno == errorcode.er_bad_db_error:
print("database does not exist")
else:
print(err)
else:
conn.close()
3.3 mysqldb查詢和插入操作
#!/usr/bin/python
#coding=utf-8
import mysqldb
class mysqldbdemo(object):
def __init__(self):
pass
def connect(self):
conn = mysqldb.connect("host_ip","user","password","database")
conn.close()
def query(self,sql):
conn = mysqldb.connect("host_ip","user","password","database")
cursor = conn.cursor()
try:
cursor.execute(sql)
values = cursor.fetchall()#返回是乙個由元組構成的tuple，每乙個元組是一行值
print type(values)
for i in values:
print i
except:
print "error: unable to fecth data"
conn.close()
def insert(self,sql):
conn = mysqldb.connect("host_ip","user","password","database")
cursor = conn.cursor()
try:
cursor.execute(sql)
conn.commit()
except:
conn.rollback()
conn.close()
