首先开启开启oracle数据库,同时也要开启侦听端口,使用命令lsnrctl status产看,lsnrctl start开启 import cx_Oracle db=cx_Oracle.connect('system','dingjia','192.168.88.213/orcl11') #获取connection对象 cursor=db.cursor() #获取游标对象 create_table="""create table python_modules( module_name VARCHAR2(50...
db = cx_Oracle.connect('username/password@ip:port/sid') cr = db.cursor() except: print('database connection faile') # 需要插入的数据 ''' 数据库中的字段类型对应:int,varchar2,timestamp,timestamp,int ''' id = '' name_id = "5df455ggrg4e5r5sagf5666f" Get_time = time.strftime("...

我尝试使用python的Pool运行多个进程,每个进程都将查询数据库这就是为什么我尝试将连接传递到每个进程,然后启动一个新的游标来执行查询db = DBConnection() sessoion_poolconnection)) 然而,它一直抛出TypeError: can't pickle cx_Oracle.Connection objects我也尝试过对Session执行同样的操作,并在函数逻辑中使用 ...

db_conn = cx_Oracle.connect(“user/pass@tnsname.world”) 如果import cx_Oracle 报错ImportError: DLL load failed: 找不到指定的程序。 可以使用Dependency Walker这个工具打开 cx_Oracle.pyd, 看看到底还缺哪些dll Dependency Walker下载地址: http://www.dependencywalker.com/ ...
1、安装配置cx_Oracle模块 Window系统配置 1）安装cx_oracle模块 pip3 install cx_Oracle 2）下载所需的软件包vcredist_x64.exe，instantclient-basic-windows.x64-11.2.0.4.0.zip（根据⾃⼰连接oracle数据库版本和系统位数下载）3）解压instantclient-basic-windows.x64-11.2.0.4.0.zip，然后点击运⾏...
