1.instantclient-basic-windows.x64-11.2.0.4.0.zip(64位) --这个必须要安装

(地址中有vcredist_x64.exe和instantclient-basic-windows.x64-11.2.0.4.0.zip,还有个说明!)
2.Oracle 11gR2 (64位)
最好要保持Python、instantclient和Oracle位数一致(我本机安装的都是64位的)!!!
二、步骤:
2.1 把instantclient-basic-windows.x64-11.2.0.4.0.zip解压到某一目录并把目录配置到系统环境变量Path中
2.2 下载安装vcredist_x64.exe,安装好后重启电脑,必须要重启一下
2.3 安装cx_Oracle: pip install cx_Oracle
2.4 pycharm中执行样例:
import cx_Oracle class My_plsq: def my_cha(self,my_sql_c): try: conn = cx_Oracle.connect("用户名/密码@127.0.0.1:1521/orcl") # conn = cx_Oracle.connect("连接名","密码","localhost/orcl") cursor = conn.cursor() cursor.execute(my_sql_c) all_data = cursor.fetchall() return all_data except Exception as e: return print("执行出错了!",e) if __name__ == '__main__': a=My_plsq() l=a.my_cha("SELECT * FROM cpq_config") print(l)
