Python cx_Oracle

News

cx_Oracle has a major new release under a new name and homepage python-oracledb.

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_Oracle is a Python extension module that enables access to Oracle Database. It conforms to the Python database API 2.0 specification with a considerable number of additions and a couple of exclusions. See the homepage for a feature list.

cx_Oracle 8.3 was tested with Python versions 3.6 through 3.10. You can use cx_Oracle with Oracle 11.2, 12c, 18c, 19c and 21c client libraries. Oracle's standard client-server version interoperability allows connection to both older and newer databases. For example Oracle 19c client libraries can connect to Oracle Database 11.2. Older versions of cx_Oracle may work with older versions of Python.
