"Oracle PL/SQL Best Practices", from the same author as "Oracle PL/SQL Programming".Purchased it earlier today. Fortunately, this is one of the more reasonably priced O'Reilly books. Hard to swallow those $40, $50, and $60 titles. This one at $20 is more to my liking.
9i doesn't seem terribly different to me. There are some additions to the object stuff (inheritance, mainly).Great. Means the older books should be useful (and cheap).
Just because it was easy, here's the [link|http://www.angelfire.com/tx4/cus/shapes/plsql.html|PL/SQL shapes]. Probably won't be using inheritance and OO soon in PL/SQL, but I did notice several quirks. First, you have to drop all the subtypes manually before you can recompile a base type. Second, the constructor mechanism seems kind of flimsy - relying on declaration order within the types. Third, SELF is optional for accessing member properties and functions but is required for access to the same in the superclass.
TOra.Looks good. Downloaded but haven't had time to do much exploring.
