Bayross loves the TABLE datatype (Index-by tables). That is fine. But he barely touches Bulk Collect and FORALL . In modern Oracle, if you are still looping through cursors row-by-row like Bayross taught you, your PL/SQL will run slower than a SQL query from 1999.
Ironically, this low-fidelity scan taught a valuable lesson: You had to squint to see the %ROWTYPE attribute. You had to infer the missing semicolon because the scan cut it off. It forced you to think, not just copy-paste. What the PDF Gets Right (Even Today) Before you dismiss Bayross as obsolete, open the PDF. Look at Chapter 11: Exception Handling.
And honestly? That is a pretty good ghost to have. Note to the reader—Ivan Bayross also wrote "The C Programming" text. If you find a PDF of that, you might have discovered the Rosetta Stone of 90s Indian computer science education. pl sql ivan bayross pdf
But it starts every time. It turns the key, and the engine runs.
You won't find modern analytic functions. You will find a lot of || concatenation and manual string hacking. Bayross loves the TABLE datatype (Index-by tables)
But never forget: Every time you type DBMS_OUTPUT.PUT_LINE('Hello World'); , you are channeling the ghost of Ivan Bayross.
You know the one. The pages are slightly tilted. The font is a weird Times New Roman from a 1997 word processor. There are handwritten notes in the margins from a student who studied before you. In modern Oracle, if you are still looping
For a generation of Indian engineers and self-taught database developers, "PL/SQL by Ivan Bayross" wasn't just a book; it was a rite of passage. But in 2024, with the rise of modern SQL, JSON in Oracle, and AI copilots, is this dusty PDF worth your hard drive space?
If you are a student preparing for an exam, download the PDF. Memorize the cursor loop. Pass the test.
