python3在oracle插入中文編碼問題

正常讀取

• 讀取解決中文亂碼，修改一下變量保持和oracle一致

import os
os.environ['NLS_LANG'] = 'SIMPLIFIED CHINESE_CHINA.UTF8'

• 查看oracle的NLS_LANG

select * from V$NLS_PARAMETERS;
select userenv(‘language’) from dual;

正常insert和update

• 需要修改os.py源文件：C:\Users\Administrator\AppData\Local\Programs\Python\Python36-32\Lib
• 把字符集變量加進去聲明的下面就可以了
