  • Presentation: New PL/SQL Features in Action (PDF)
    Presented as paper #32501 at OracleWorld, San Francisco, Nov 2002
    Both Oracle9i Database Release 1 and Release 2 introduced powerful new PL/SQL features. In this paper, we focus on just two: Native compilation of PL/SQL; and index-by-varchar2 tables.
    We will review the details of these enhancements and provide complete code samples to enable you to understand them and to test thier performance.

    Use the new PL/SQL features in Oracle9i Database to get better programs by writing fewer code lines
  • Presentation: Less Pain, More Gain (PDF)
    Presented as paper #30720 at OracleWorld, Copenhagen, June 2002
    Both Oracle9i Database Release 1 and Release 2 introduced powerful new PL/SQL language features. These allow you to implement your required functionality using compact syntax backed by an efficient implementation. This paper will examine some very common programming tasks. We'll remind you how you would have had to implement them in versions prior to Oracle9i Database. And we'll show you the new recommended approach. You'll see that you need fewer lines of code. We'll explain why the program will be more efficient. Another reason you often used to write more code than you wanted was to call Dbms_Output.Put_Line, the de facto debugging tool of choice. We'll demonstrate how you can now forget that and debug your programs interactively using Oracle9i JDeveloper's graphical PL/SQL development environment.

  • White Paper: Best Practices in PSP Development (PDF)
    This paper presents guideline for best practice in the development of PL/SQL Server Pages (aka PSPs). It also explains what a PSP is, and gives guidelines for deciding whether to implement a browser page as a PSP or as a hand-written PL/SQL procedure. Though it was commissioned as one of a set of best practices papers for Oracle9iAS, it is equally applicable for applications which use the webserver which is shipped with Oracle9i Database.
