python 版本:3.6 win32 版本(因为一些特殊原因必须使用3.6)
pymssql 版本:2.2.0
连接数据库:
- import pymssql<br>**<br> def InitMssql(self):
- try:
- host = self.IniConfig.get('default','dbhost',"host***")
- user= self.IniConfig.get('default','dbuser',"dbs***")
- password = self.IniConfig.get('default','dbpassword',"pwd***")
- database = self.IniConfig.get('default','dbdatabase',"db***")
- #self.DBconn = pymssql.connect(host,user,password,database,charset="GBK")
- self.DBconn = pymssql.connect(host,user,password,database)
- self.DBcursor = self.DBconn.cursor()
- sql = "SET TEXTSIZE 2147483647"
- self.DBcursor.execute(sql)
- self.DBconn.commit()
- except Exception as ex:
- if self.DBconn: self.DBconn.rollback()
- raise ex
复制代码
报错信息如下:

尝试解决1:加charset参数,失败
在网上搜相关信息,发现信息量很少,偶尔提到的解决方案都是加 charset参数。
譬如:
1、DB-Lib error message 20002, severity 9 - chungehpu - 博客园 (cnblogs.com) 加连接参数 charset="CP936"
2、DB-Lib error message 20002, severity 9_pymssql._pymssql.operationalerror: (20002, b'db-li-CSDN博客 也是加连接参数 charset="CP936"
3、还有github上SQL Server database encoding (GBK) is not consistent with python · Issue #820 · pymssql/pymssql · GitHub 加连接参数 charset="GBK"
尝试加连接参数,再次报同样的错误。
尝试解决2:切换到python3.4,成功。
切换到python3.4,不加charset写法,结果成功。
最终解决方案:python3.6,安装pymssql低版本(pymssql-2.1.5-cp36-cp36m-win32.whl),成功
到 Archived: Python Extension Packages for Windows - Christoph Gohlke (uci.edu) 找到pymssql 2.1.5 ,卸载原有的高版本,手工安装whl。
成功!
