What is cx_Oracle? cx_Oracle is a Python extension module that enables access to Oracle Database for Python 3.x and 2.x and conforms to the Python database API 2.0 specifications with a number of enhancements. Where do I get it? https://oracle.github.io/python-cx_Oracle The easiest method to install/upgrade cx_Oracle is via pip as in python -m pip install cx_Oracle --upgrade What's new? This release eliminates the error "DPI-1054: connection cannot be closed when open statements or LOBs exist". It also adds support for creating temporary LOBs and binding LOBs directly to a cursor. You can now also use a connection as a context manager to close the connection at the end of the block by using the new cx_Oracle.__future__ object ( http://cx-oracle.readthedocs.io/en/latest/module.html#cx_Oracle.__future__). This will become the default and only behaviour of using a connection as a context manager unless I hear otherwise! The code was reorganised and simplified in order to streamline further maintenance and a number of bugs were fixed.
