A quick disclaimer: I was inspired to write this post after reading AmberIsMe’s take on why she doesn’t read your blog. It’s not personal. Actually, it is a little personal. That is the point of social media after all, right? Building personal relationships with folks you admire that you wouldn’t otherwise be able to in ‘real life’ Don’t let me put words in your mouth, but that’s one of the primary reasons I spend a…
No matter how many monitors you have or how large they may be, sometimes you just need more real-estate for your coding. You can have a whole lot going on in your IDE, and SQL Developer is no exception. Of course you can always close or hide the offending panels and windows, but then it’s a real pain to get them back. WordPress has a nice fullscreen editor I can use when writing these posts.…
I’m not sure if I can help with the mind part, but I can definitely add some perspective on the line numbers. Quickly, let’s define just what the ‘gutter’ is in the world of programming and database GUIs. I found a good definition on Quantum Whale, a .NET component developer, and I’m going to quote them: Gutter: The gutter area can be used to display bookmarks, line numbers and outline sections. The gutter is the…
Starting with 10g and the introduction of DMBS_SCHEDULER, Oracle database began tracking and storing the execution duration of a job. By default this information is kept around for 30 days. You can of course change the logging level and the retention period for the job runs – read the docs! The job runs can be viewed via the dba_scheduler_job_run_details SYS view. Oracle SQL Developer shows this data in the job details panel of the schema…
On February 14-16, I’ll be at the Colorado Convention Center in Denver, Colorado for RMOUG’s Training Days Conference. This is the largest regional Oracle User Conference in North America and attracts presenters from all around the country and the globe. I’ll be presenting: Presentation Name: SQL Developer Tips and Tricks for Developers Abstract: You use the GUI because you want to be productive, right? Do you ever get the feeling you’re only really using a…
It’s a relational database, so it’s only a matter of time before you stumble across an object that’s dependent on another object, right? If you are looking at a table in the browser, be sure to check out the ‘Dependencies’ page. This page displays the database objects that will be upset if the selected table were to ‘go away.’ You’re probably familiar with these related objects, but if not, then there’s a quick ‘trick’ to…
Data models sure are handy. They tell a story – how does the information get stored as data? Just what is a ‘customer?’ Sometimes though our applications die and only leave legacy scripts behind. Or maybe you are a DBA and someone has given you a set of scripts to create some new objects in your database. You ask them for their model, and they just look at you with that weird blank stare. “We…
Welcome to WordPress. This is your first post. Edit or delete it, then start blogging!
I’m going to go out on a limb and guess that most people who use SQL Developer do not realize it has a fully-baked data modeling tool built into it. It’s not like we hide it, but we kind of hide it. To open the Data Modeler inside of SQL Developer, navigate to the View menu, and activate the Data Modeler Browser, like so – Once opened, you’ll see a new ‘Browser’ panel beneath your…
New for version 3.1, currently available as a EA download, when defining the queries used to populate views, the modeler can generate JOINs using either Oracle’s or the standard ANSI compliant syntax. Let’s step back a second. When working with a VIEW defined in a relational model, the modeler has twp choices for defining the driving SQL statement that is used to populate the contents of the view. They can code it by hand -…
