and 12.2 client libraries. Oracle's standard client-server version

interoperability allows connection to both older and newer databases.

For example Oracle 12.2 client libraries can connect to Oracle

<h2>Getting Started</h2>
|
||||
|
||||
<ul>
|
||||
|
||||
<li><p>Install Python from <a href="https://www.python.org/" >python.org</a>.</p></li>
|
||||
|
||||
<li><p>Install cx_Oracle using <a href="http://cx-oracle.readthedocs.io/en/latest/installation.html#quick-start-cx-oracle-installation" >Quick Start cx_Oracle Installation</a>.</p></li>
|
||||
|
||||
<li><p>Download cx_Oracle <a
|
||||
href="https://github.com/oracle/python-cx_Oracle/tree/master/samples"
|
||||
>samples</a> or create a script like the one below.</p></li>
|
||||
|
||||
<li><p>Locate your Oracle Database username and password, and the database
|
||||
connection string. The connection string is commonly of the format
|
||||
<code>hostname/servicename</code>, using the hostname where the database is
|
||||
running, and the service name of the Oracle Database instance.</p>
|
||||
|
||||
<p>Substitute your username, password and connection string in the
|
||||
code. For downloaded examples, put these in <a
|
||||
href="https://github.com/oracle/python-cx_Oracle/tree/master/samples/SampleEnv.py"
|
||||
><code>SampleEnv.py</code></a> and <a
|
||||
href="https://github.com/oracle/python-cx_Oracle/blob/master/samples/sql/SampleEnv.sql"
|
||||
><code>SampleEnv.sql</code></a>, and then follow <a
|
||||
href="https://github.com/oracle/python-cx_Oracle/tree/master/samples/README.md"
|
||||
><code>sample/README</code></a> to create the cx_Oracle sample schema.
|
||||
SQL scripts to create Oracle Database's common sample schemas can be
|
||||
found at <a href="https://github.com/oracle/db-sample-schemas"
|
||||
>github.com/oracle/db-sample-schemas</a></p> </li>
|
||||
|
||||
<li><p>Run the Python script, for example:</p>
|
||||
|
||||
<pre>
|
||||
python myscript.py
|
||||
</pre>
|
||||
</li>

<h2>Installation</h2>
|

See <a

>cx_Oracle Installation</a> for detailed instructions.
|
||||
|
||||
<ul>
|
||||
|
||||
<li>
|
||||
<p>The simplest way to install cx_Oracle is with pip:</p>
|
||||
<pre>
|
||||
python -m pip install cx_Oracle --upgrade
|
||||
</pre>
|
||||
<p>If a binary wheel package is not available on <a
|
||||
href="https://pypi.python.org/pypi/cx_Oracle" >PyPI</a> for your
|
||||
platform, the source package will be used.</p>
|
||||
|
||||
<p>Note that if you download a source zip file directly from GitHub
|
||||
then you will also need to download an <a
|
||||
href="https://oracle.github.io/odpi" >ODPI-C</a> source zip file and
|
||||
extract it inside the directory called "odpi". </p>
|
||||
|
||||
</li>
|
||||
|
||||
<li>
|
||||
<p>After cx_Oracle is installed, Oracle client libraries must
|
||||
also be installed and configured. These can be from Oracle Instant
|
||||
Client, from a local Oracle Database, or from a full Oracle Client
|
||||
installation.</p>
|
||||
|
||||
<p>If you need the libraries, download and unzip the <a
|
||||
href="http://www.oracle.com/technetwork/database/features/instant-client/index.html"
|
||||
>Oracle Instant Client</a> 'Basic' package for your platform and set
|
||||
PATH, LD_LIBRARY_PATH, or similar platform-specific library path
|
||||
loading environment. See the <a
|
||||
href="https://oracle.github.io/odpi/doc/installation.html"
|
||||
>installation notes for ODPI-C</a> for help.</p>
|
||||
|
||||
<p>Versions 11.2, 12.1 and 12.2 of the Oracle Client libraries on Linux,
|
||||
Windows and macOS are supported. Users have also reported success
|
||||
with other platforms.</p>
|
||||
|
||||
</li>
|
||||
</ul>
|
||||
|
||||
<p>If you require cx_Oracle 5.3, download a Windows installer from <a
|
||||
href="https://pypi.python.org/pypi/cx_Oracle/5.3" >PyPI</a> or use
|
||||
<code>python -m pip install cx-oracle==5.3</code> to install from
|
||||
source.</p>
|
||||
|
||||
<p>Very old versions of cx_Oracle can be found in the files section at
