Welcome to python-oracledb’s documentation!

Python-oracledb is the new name for the Python cx_Oracle driver. The python-oracledb driver is an open source module that enables Python programs to access Oracle Database. It conforms to the Python Database API v2.0 Specification with a considerable number of additions and a couple of exclusions. Synchronous and concurrent coding styles are supported.

This module is currently tested with Python 3.7, 3.8, 3.9, 3.10, 3.11 and 3.12 against Oracle Database 23c, 21c, 19c, 18c, 12c, and 11gR2.

python-oracledb is distributed under an open-source license. Changes in python-oracledb releases can be found in the release notes.

You can use assistive technology products, such as screen readers, while you work with the python-oracledb documentation. You can also use the keyboard instead of the mouse.
