2、MySQL的操作及应用

import MySQLdb

# MySQL相关设置
mysql_host = '10.202.44.155'
mysql_user = 'test'
mysql_passwd = 'test'
mysql_port = '3306'
mysql_database = 'test'

def my_connect():
"""链接数据库"""

global conn, cursor

#print MySQLdb.version_info

try:
conn = MySQLdb.connect(host=mysql_host, user=mysql_user, passwd=mysql_passwd,charset='utf8', autocommit=True, db=mysql_database)

print u"\nMesses:连接MySQL成功"
except Exception:
print(u'\nMesses: 连接失败' )
exit(20)
cursor = conn.cursor()

def add():

#add
sql = "insert into user(name,age) values(%s,%s)"
param = ("tom",str(20))
n = cursor.execute(sql,param)
print n
def update():
#更新
sql = "update user set name=%s where Id=9001"
param = ("ken")
n = cursor.execute(sql,param)
print n
def Select():
#查询
try:
n = cursor.execute("SELECT t.mainWaybillNo,t.opCode from track t  ORDER BY t.insertTime DESC LIMIT 2")

data = cursor.fetchall()
for row in data:
#注意int类型需要使用str函数转义
print("\nmainWaybillNo: " + row[0] + '  opCode: '+row[1])

print ""
#提交事务
conn.commit()
cursor.close()#关闭游标
conn.close()#释放数据库资源
except  Exception :

#异常情况下，进行事务回滚
conn.rollback()
print(u"\n操作失败,数据已回滚")
def delete():
#删除
sql = "delete from user where name=%s"
param =("ted")
n = cursor.execute(sql,param)
print n
cursor.close()

my_connect()
Select()
