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…
We spend a lot of time here talking about tips, tricks, and cool things that you might have missed. These posts generally all assume you’ve been around the Oracle Database block. But many of the folks that ultimately end up here, have NEVER touched an Oracle Database before. This post is for you. You have decided to use SQL Developer, which is good. Because I can think of at least 10 reasons why SQL Developer…
Oracle SQL*Plus has been around since 1985. It does what it does, and it does it well. SQL Developer has been around since 2006. It’s become the de facto IDE and GUI for the Database. There was an opportunity to build something new that could take the command line interface and enhance it to meet the needs of today’s database professional. So really the question that our team was faced with wasn’t ‘Why?’ it was..…
If you know how to edit your code in SQL*Plus, you already know how to do it in SQLcl. But I get asked this a lot, do you support EDIT? Do you support CHANGE? And what does SQLcl offer over those? So let’s tackle the old and then the new… C/Old/New SQL*Plus has the C[HANGE] command. C[HANGE] sepchar old [sepchar [new [sepchar]]] Changes the first occurrence of the specified text on the current line in…
You may want to audit or ‘journal’ changes to your data. As you update a record, add a record, or delete a record – log that change in a different table. When doing your designs in the Data Modeler, you can ask at the time of DDL generation to have the journaling table and trigger created for one or more of your relational design tables. Step One: Hit the DDL button. For each table, you’ll…
