Oracle SQL Developer Command Line (SQLcl) is the full name for what we’ve been calling, SQLcl. Have you seen the video? It’s only 8 minutes and will catch you up on just what SQLcl is. Anyways, there’s a ‘new’ command called SCRIPT that I want to show you today. I say ‘new’ because we added this in October of 2015. Stealing from @krisrice… This new command can radically change things you can do in the…
In SQL Developer we have color coded connections. This was added, not because we like Christmas trees and all the pretty lights, but because sometimes you need a reminder of what database you’re on. So you don’t TRUNCATE stuff, accidentally. Visual cues won’t prevent all mistakes, but they sure help. With SQLcl, you have the abilty to setup your SQL prompt with custom text and colors. This works better if you have a decent terminal.…
I have an UMLAUT table. Pretty simple really… 56815603767261b16e2708_000003 Looks great in SQLDev, but not so much in SQLcl… Everything is UNICODE by default in Java applications. It’s converted to Unicode coming in and going out… [docs] This is a HUGE advantage in the Java world. We don’t have to do anything special when it comes to supporting Unicode. So what’s happening above? Windows CMD by default isn’t setup to use a Unicode code page.…
If there is a Madonna or Prince in the Oracle Database world, that would be Tom. You know, people that are known solely by their first name. Of course there’s also Larry, but from a pure database tech perspective, Tom has satiated the curiosity of developers and DBAs for the past couple of decades. If you were stuck with a technical challenge, or just needed help settling a bar bet – what’s better, count(*) or…
Not to start a religious war, but white space in your code can cause havoc when you’re doing code compares and versioning. Some folks like tabs, others prefer to control how their code looks regardless of the editor’s tab display options. From what I can tell, SQL Developer’s code editors won’t even let you insert a tab into them – they auto-convert a tab into 2 spaces. But, if you’ve pasted tabbed code in, they’ll…
Question: Why is SQLcl truncating my column header names? It doesn’t do it if I use SET SQLFORMAT ANSICONSOLE though… Answer: Because, SQL*Plus. Longer Answer: SQLcl follows the SQL*Plus rules. And in this case, the rule is: The default width of CHAR and VARCHAR2 (VARCHAR) columns is the width of the column in the database. The questioner was seeing that the 2nd column in their query was having its column name truncated – because it…
I say designing, because I’m going to be talking about how to do this in SQL Developer Data Modeler. And I say Part Two, because in a previous post I showed how to draw a foreign key in your relational design. This post discusses how to control the generation of the foreign key column: to generate or not if generated, how to name it Let’s start by defining the ‘foreign key column.’ If we have…
It’s that time of year again. You’re jealous from hearing all about that fabulous conference your co-worker or Facebook buddy just got back from. You could NEVER make it a conference. Your company just doesn’t do that. If you want to go to a top-tier Oracle user group or industry conference next year, it’s time to start asking about it, today. Don’t Call It a Conference – It’s Training You say conference, your boss will…
I talked about using the debugger to inspect a collection in PL/SQL using SQL Developer a few years ago. It’s been so long in fact that when Steven asked if I had a post on it, I said ‘no.’ We had gotten a question from a reader on how to look at collections while you’re debugging them. If you want to read about this topic in general, Steven’s article in Oracle Magazine is a great…
I try to keep my fonts ‘big’ – for folks reading my posts and for folks attending my sessions. I do lots and lots of live demo’s, and there’s a lot of code on the screen to keep track of. But I’ve generally not followed my own advice when working in a cmd shell. Oops! Fixed for next week, when I’ll be doing lots of live demo of our new favorite command line interface to…
