@eaandersen thanks a lot for the PR. To keep it cleaner, would you mind creating a Oracle connector extending the SQL connector that overrides the default value for rand? That would be a cleaner and easier to maintain solution.

It makes perfect sense to extend the SQLConnector and create a separate class for Oracle. I'll send an update in the next day or two.

@eaandersen thanks a lot, really appreciated!

Updates completed. I created a separate class for Oracle, extending the SQL connector. Added required unit tests and everything passed. Also added a check for connection close to avoid NoneType errors. Updated TOML with optional cx_Oracle. Let me know if you're okay with these changes.
