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?

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 addresses a number of issues and bug fixes. The changes needed
to support DML Returning with cursor.executemany() required a new point
release since the attribute dml_ret_array_val in the cx_Oracle.__future__
object needs to be set in order for it to work correctly. Setting it
changes the behavior for DML Returning statements with cursor.execute() as
well and will become the new behavior in cx_Oracle 7. See the release notes
for more information.
