I’ve spent the last few years largely abstracted from relational database DDL, relying on DBAs or frameworks (e.g., Hibernate) to do that for me or working with alternate persistence technologies (e.g., an XML database, Web Services, etc.).
For a quick project, I’m working with raw Oracle DDL, and I’m a little shocked at how primitive it is. Still no auto-incrementing type? Still no boolean type? Really?
