环境：ubuntu14.04，python2.7

这篇文章只是为了记录我碰到的一个mysql相关的小问题

看了下代码，就是爬取bili用户信息后保存到mysql中。因为想之后方便提取mysql里的信息，所以将mysql相关的代码修改，放到另一个模块。

其中添加数据的代码如下：

class Ch_mysql():

def __init__(self):

self.conn = pymysql.connect(host='127.0.0.1', port=3306, user='user',

passwd='passwd', db=database, charset='utf8')

def add(self, kwargs):

mid = kwargs.get('mid', None)

name = kwargs.get('name', None)

sex = kwargs.get('sex', None)

face = kwargs.get('face', None)

coins = kwargs.get('coins', None)

regtime = kwargs.get('regtime', None)

spacesta = kwargs.get('spacesta', None)

birthday = kwargs.get('birthday', None)

place = kwargs.get('place', None)

description = kwargs.get('description', None)

article = kwargs.get('article', None)

fans = kwargs.get('fans', None)

friend = kwargs.get('friend', None)

attention = kwargs.get('attention', None)

sign = kwargs.get('sign', None)

attentions = kwargs.get('attentions', None)

level = kwargs.get('level', None)

exp = kwargs.get('exp', None)

sql = "INSERT INTO bilibili_user_info VALUES (%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s)"

try:

cur = self.conn.cursor()

cur.execute(sql, (mid, mid, name, sex, face, coins, regtime, spacesta, birthday, place, description,

article, fans, friend, attention, sign, str(attentions), level, exp))

cur.close()

# raise # for test

self.conn.commit() # commit之后raise不会回滚了

except Exception, e:

print 'db Exception: ', e

self.conn.rollback()

finally:

# cur.close()

# self.conn.commit()

self.conn.close()

这是改好的代码，之前代码中sql因为用的单引号，所以一直报错：unsupported operand type(s) for %: 'tuple' and 'tuple'

查了些文章说是python的问题，搞不清原因，后来照以前的代码意义对比，将单引号改为双引号后就好了

呃，总之还不清楚为什么这样，聊作记录而已
