如何处理Python3.4 使用pymssql 乱码问题

338次阅读  |  发布于5年以前

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")
