Describe the environment

Mac M1 Ventura 13.4

** Solution **

Adapt the oracle.py file with the proposed changes here

https://python-oracledb.readthedocs.io/en/latest/user_guide/appendix_c.html#steps-to-upgrade-to-python-oracledb

I edited it like this and it worked

@import_helper("oracle")
def import_oracle():
    #import cx_Oracle
    import oracledb as cx_Oracle
    return cx_Oracle`

Not sure if you can add this by default to the oracle.py driver?

@koenvb could you open a PR with your proposed change?

Hi @koenvb,

I'm sorry for the delay in following up on this. Thank you for taking the time to raise this issue!

We made a hard decision to sunset the data-diff package and won't provide further development or support.

Data diffing continues to be provided and has evolved in the Datafold Cloud.
