Is there even a grammar for Oracle SQL? I took a swing at trying to slurp it out of the "alt text" of the railroad images in the many, many html files in (e.g. https://docs.oracle.com/en/database/oracle/oracle-database/2... -> https://docs.oracle.com/en/database/oracle/oracle-database/2... ) but then I thankfully moved off any project from that point on that used Oracle and let it go

I'm aware of https://github.com/orafce/orafce and https://github.com/pgoracle before that (the commit history also references ora2pg and searching for that surfaces https://github.com/darold/ora2pg which was just updated yesterday!) but I've never tried to use any of them in anger
