python-oracledb

python-oracledb is a Python programming language extension module allowing Python programs to connect to Oracle Database. Python-oracledb is the new name for Oracle's popular cx_Oracle driver.

The module conforms to the Python Database API 2.0 specification with a considerable number of additions and a couple of minor exclusions, see the feature list.

Synchronous and concurrent coding styles are supported.

Installation

Run python -m pip install oracledb

See python-oracledb Installation.

Dependencies and Interoperability

• Python versions 3.8 through 3.13.

  Prebuilt packages are available for these Python versions on Windows, on macOS and on Linux.

  Source code is also available.

• Oracle Client libraries are optional.

  Thin mode: By default python-oracledb runs in a 'Thin' mode which connects directly to Oracle Database.

  Thick mode: Some advanced Oracle Database functionality is currently only available when optional Oracle Client libraries are loaded by python-oracledb. Libraries are available in the free Oracle Instant Client packages. Python-oracledb can use Oracle Client libraries 11.2 through 21c.

• Oracle Database

  Thin mode: Oracle Database 12.1 (or later) is required.

  Thick mode: Oracle Database 9.2 (or later) is required, depending on the Oracle Client library version. Oracle Database's standard client-server version interoperability allows connection to both older and newer databases. For example when python-oracledb uses Oracle Client 19c libraries, then it can connect to Oracle Database 11.2 or later.
