Scripting in SQLcl - You can never have enough of a good thing

So, you’ve been introduced to SQLcl, and because it’s such an awesome tool with so many incredible features, now it’s your preferred command line utility for talking to the database. Unfortunately this functionality that would make your life so much easier is not included, or implemented in a way that is not useful enough for you. And your idea just doesn’t get implemented in SQLcl (soon enough).What can you do? Wait? Complain? Tell everybody the tool stinks? No, of course not. SQLcl allows you to script your own functionality using JavaScript and Java, and even include it as your own custom commands.This talk will introduce you to what it takes to include your own custom functionality in SQLcl found nowhere else (unless you share it). You will learn what it takes to create and execute scripts and how to register and unregister them as custom commands. We will also go through a real script beyond simple hello-world code to see what it does and how.
