These are examples for the cx_Oracle driver.
Download and install from PyPI or issue the command
python -m pip install cx_Oracle --upgrade
After installing cx_Oracle, the demos can be run by executing each script file with Python. The scripts all assume that the cx_Oracle test suite objects have been installed in your database and that the connect string "cx_Oracle/dev@localhost/orcl" is valid. If this is not correct, adjust the connect string before running the test.
