Monday morning. The first day back at work in the New Year.
Still groggy, having been awoken from my slumber at the insistence of my Darth Vader Lego Alarm Clock, I stagger downstairs in search of coffee.

So for him, and any other programmers who want to get up and running with PL/SQL, but don’t need to be told what a variable is, what follows is – not so much a PL/SQL 101 – as a PL/SQL 23-and-a-bit. Continue reading →
