Question

我想从Python脚本连接到Oracle数据库。为此，我正在尝试安装cx_oracle Python模块。我的Linux机器上没有安装Oracle。

安装cx_oracle模块时，会抛出错误，说“无法找到Oracle软件安装”

有没有办法从python连接到Oracle数据库而无需在Linux机器中安装Oracle。

-bash-4.1$ pip install cx_Oracle
DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python. A future version of pip will drop support for Python 2.6

Answer 1

如果只是为了避免不受支持的软件带来的安全问题，我肯定会建议升级您的Python安装。您可以从https://www.python.org/downloads下载新版本。根据您的操作系统，可能有多种方法可以安装Python的替代版本。

但是，仍然可以支持Python 2.6。如果您使用的是Oracle Linux 6或RHEL 6，则可以从here下载RPM。

如果您需要从源代码构建，最简单的解决方案是使用带有pip的cx_Oracle 6使用以下命令：

pip install cx_Oracle --upgrade --pre

cx_Oracle 6不需要安装Oracle客户端，但cx_Oracle 5及更早版本可以安装。

在运行时，所有版本的cx_Oracle都需要Oracle客户端。最简单的安装是Oracle Instant Client，您可以找到here。

sqlplus_commando可能确实是你需要的。

您可以在代码中使用此驱动程序：

from sqlplus_commando import SqlplusCommando

sqlplus = SqlplusCommando（hostname =＆＃39; localhost＆＃39;，database =＆＃39; test＆＃39;， username =＆＃39; test＆＃39;，password =＆＃39; test＆＃39;） result = sqlplus.run_query（＆＃34; SELECT 42 AS response，＆＃39;这是一个测试＆＃39; AS问题来自DUAL;＆＃34;）打印结果
