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 #------------------------------------------------------------------------------- # Name: pymssqlTest.py # Purpose: 测试 pymssql库,该库到这里下载:http://www.lfd.uci.edu/~gohlke/pythonlibs/#pymssql # # Author: scott # # Created: 04/02/2012 #------------------------------------------------------------------------------- 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()
三水点靠木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")
