Modifying a part (one procedure) in oracle database package Is it possible to modify an individual procedure inside an Oracle DB Package? instead of recreating (modification is not done using a SQL editor, so cannot modify a place and easily recompile the package) the package again every time we need to do a minor change?

Thanks.
Don't. Keep all your package sources in a source control system. That way you can go back to a previous version if you need to.
