1、cx_Oracle.DatabaseError: ORA-24315: illegal attribute type
2、cx_Oracle.InterfaceError: Unable to acquire Oracle environment handle
Python通過cx_Oracle模組連線oracle資料庫報如上錯誤，都是應為oracle客戶端的問題導致，只需要將對應版本的*.dll（10g：oci.dll, oraociei10.dll, oraocci10.dll；11g：oci.dll, oraociei11.dll, oraocci11.dll）檔案拷貝至
C:\Users\Administrator\AppData\Local\Programs\Python\Python36\Lib\site-packages下或者C:\Users\Administrator\AppData\Local\Programs\Python\Python36-32\Lib\site-packages下
即可解決。
