importcx_Oracle db_conn=cx_Oracle.connect(“user/pass@tnsname.world”) 二、安装plsql developer及其对应Oralce客户端 安装PLSQL Developer,这是一个Oracle可视化软件,用来操作Oracle数据库。 下载Oracle 32位客户端(Oracle Instant Client),目前plsql只支持Oracle 32客户端。可以到http://www.oracle.com/technet...
cx_Oracle操作oracle数据库 cx_Oracle 操作oracle数据库 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-...
如果PL/SQL块只执行单个查询,则直接执行该查询,而不使用PL/SQL:
The source code has moved to github.com/oracle/python-oracledb. New projects should install python-oracledb instead of cx_Oracle. Critical patches and binary packages for new Python releases may continue to be made in the cx_Oracle namespace for a limited time, subject to demand. About cx_...
7. 根据 python 的版本和 Oracle 客户端的版本, 下载合适的 cx_Oracle 编译包. (http://cx-oracle.sourceforge.net/). 安装之. 8. 测试 cx_Oracle import cx_Oracle 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...
