在项目中发现这样一个问题:sqlserver数据库编码为gbk,使用python3.4+pymssql 查询,中文乱码,经过一番思考问题解决,下面把解决办法分享给大家:
conn = pymssql.connect(host=”192.168.122.141″,
port=1433,
user=”myshop”,
password=”oyf20140208hh”,
database=”myshopcmstock”,
charset=’utf8′,
as_dict=true) cur = conn.cursor()sql = “select top 10 [id],[name] from [user]”cur.execute(sql)list = cur.fetchall()for row in list: print(row[“id”],row[“name”].encode(‘latin-1’).decode(‘gbk’))
接下来给大家介绍python 使用pymssql连接sql server数据库
#coding=utf-8
#!/usr/bin/env python

import pymssql
class mssql:
“””
对pymssql的简单封装
pymssql库,该库到这里下载:http://www.lfd.uci.edu/~gohlke/pythonlibs/#pymssql
使用该库时,需要在sql server configuration manager里面将tcp/ip协议开启
用法:
“””
def __init__(self,host,user,pwd,db):
self.host = host
self.user = user
self.pwd = pwd
self.db = db
def __getconnect(self):
“””
得到连接信息
返回: conn.cursor()
“””
if not self.db:
raise(nameerror,”没有设置数据库信息”)
self.conn = pymssql.connect(host=self.host,user=self.user,password=self.pwd,database=self.db,charset=”utf8″)
cur = self.conn.cursor()
if not cur:
raise(nameerror,”连接数据库失败”)
else:
return cur
def execquery(self,sql):
“””
执行查询语句
返回的是一个包含tuple的list,list的元素是记录行,tuple的元素是每行记录的字段
调用示例:
ms = mssql(host=”localhost”,user=”sa”,pwd=”123456″,db=”pythonweibostatistics”)
reslist = ms.execquery(“select id,nickname from weibouser”)
for (id,nickname) in reslist:
print str(id),nickname
“””
cur = self.__getconnect()
cur.execute(sql)
reslist = cur.fetchall()
#查询完毕后必须关闭连接
self.conn.close()
return reslist
def execnonquery(self,sql):
“””
执行非查询语句
调用示例:
cur = self.__getconnect()
cur.execute(sql)
self.conn.commit()
self.conn.close()
“””
cur = self.__getconnect()
cur.execute(sql)
self.conn.commit()
self.conn.close()
def main():
## ms = mssql(host=”localhost”,user=”sa”,pwd=”123456″,db=”pythonweibostatistics”)
## #返回的是一个包含tuple的list,list的元素是记录行,tuple的元素是每行记录的字段
## ms.execnonquery(“insert into weibouser values(‘2′,’3’)”)
ms = mssql(host=”localhost”,user=”sa”,pwd=”123456″,db=”pythonweibostatistics”)
reslist = ms.execquery(“select id,weibocontent from weibo”)
for (id,weibocontent) in reslist:
print str(weibocontent).decode(“utf8”)
if __name__ == ‘__main__’:
main()
脚本之家提醒大家需要注意事项:
使用pymssql进行中文操作时候可能会出现中文乱码,我解决的方案是:
文件头加上 #coding=utf8
sql语句中有中文的时候进行encode
insertsql = “insert into weibo([userid],[weibocontent],[publishdate]) values(1,’测试’,’2012/2/1′)”.encode(“utf8”)
连接的时候加入charset设置信息
pymssql.connect(host=self.host,user=self.user,password=self.pwd,database=self.db,charset=”utf8″)
