I'm a Java programmer (Sun certified) and I am now trying to learn Oracle PL/SQL and to take the Oracle certification exam. I am using a textbook "Oracle8 PL/SQL programming" by Scott Urman, and published by Osborne McGraw Hill which I bought about 2-3 years ago. I am currently on chapter 4. I hear a lot about Oracle 9i which I gather is the latest Oracle version. Since this book is all I have, I've been using it to study Oracle PL/SQL. But someone told me some days ago that Oracle 8 is different from Oracle 8i and that Oracle 8 predates Oracle 8i. Is this true? Igf it is, would you advice that I stop using it and get something more in line with the times?
of course, the latest book is better for exam purpose, maybe u could download the PL/SQL programming guide from oracle. the difference between old one & new, maybe some OO feature, which may not be used mostly in practice.
