达梦数据库dm8与PYthon连接访问>

达梦数据库
===================
主机名LOCALHOST

账号名
SYSDBA

登录密码
123456789

数据库名DAMENG

实例名DMSERVER

端口5236

=====================
Pycharm默认没有连接达梦的驱动，首先选择给Pycharm添加一个达梦的驱动。

找到自己电脑上达梦的JDBC驱动，因为我电脑上安装了达梦数据库，所有的驱动文件都在他的安装目录里。

通过驱动方式选择创建数据库连接。
SYSDBA
123456789
jdbc:dm://127.0.0.1:5236?schema=PRODUCTION
