Python-oracledb 1.2 has been released

python-oracledb 1.2, the extremely popular Oracle Database interface for Python, is now on PyPI.

python-oracledb is an open source package for the Python Database API specification with many additions to support advanced Oracle Database features. It is the new name for the cx_Oracle driver.

Another welcome patch release has landed, adding features that were previously only available in traditional ‘Thick’ mode (with Oracle Client Libraries). Other improvements and bug fixes were also made.

Main Changes

  • Binary packages were added for the new Python 3.11 release.
  • Support for binding and fetching data of type oracledb.DB_TYPE_OBJECT in Thin mode. This was one of the top requests that was blocking people moving from Thick mode.
    You can play with examples like this nice one that shows Oracle Database’s Spatial functionality:
  • Thin mode now has support for fetching SYS.XMLTYPE data as strings. Unlike in Thick mode, fetching longer values does not require converting your queries to return a LOB with XMLTYPE.GETCLOBVAL().
    For examples, see the documentation: Using XMLTYPE Data
  • Some connection string syntax and wallet enhancements were made to Thin mode at the request of users. These increase the number of environments that can migrate from Thick mode.

One other change I’ll mention is a new, runnable example showing loading from CSV files. The sample shows how the batcherrors flag can be used to filter out ‘noisy’ data while still letting valid rows be inserted. Loading from CSVs is an FAQ so it is nice to have the example to augment our documentation on the topic.

See the Release Notes for more improvements and bug fixes.
