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")
