While SQL Developer may be ‘perfect for Oracle beginners,’ that doesn’t preclude advanced and intermediate users from getting their fair share of toys! I’ve been working with Oracle since the 7.3.4 days, and I think it’s pretty safe to say that the WAY an ‘old timer’ uses a tool like SQL Developer is radically different than the ‘beginner.’ If you’ve been reluctant to use SQL Developer because it’s a GUI, give me a few minutes…
Learning new technologies can be daunting. If you’ve never used a Mac before, you’ll probably be a bit baffled at first. But, you’re probably at least coming from a desktop computing background (Windows), so you common frame of reference. But what if you’re just now learning to use a relational database? Yes, you’ve played with Access a bit, but now your employer or college instructor has charged you with becoming proficient with Oracle database. Here’s…
Oracle Development Tools User Group (ODTUG) puts on an outstanding event, and I enjoy that the content comes FIRST. Yes, the after-event parties and entertainment are first class, but I look forward most to sitting in on some excellent sessions. For Kscope12 one would expect Oracle to have a large presence, and you would be absolutely correct! The APEX team will be there in full force, and we’ll have sessions on JDeveloper, ADF, and .NET.…
There are several ways to get data from a query or a table|view to the clipboard. You know the tried and true, copy and paste. But what if you only want one or more columns, not every column? There are several ways to do this, let’s see if we can’t identify all of them. Write your query to only include the data you want Obvious? Yes. Needed to be said? Definitely. The best tuning tip…
Updated November 30, 2014 You’ll usually find short and sweet posts here about my day job, Oracle Database and its tools. This post neither short nor about Oracle. It’s about my blog, and the stuff under the hood that makes it run, WordPress. I get paid if you sign up for service with WPEngine. I don’t sell anything here, but this helps me pay for the site. Thanks, Jeff. Improve conversion rates with a faster…
I know this sounds like a REALLY weird question for many of you. Let me make one thing clear right away though, I am NOT talking about creating and replacing PLSQL objects directly into a production environment. Do we really need to talk about developers in production again? No, what I am talking about is a developer doing their work from start to finish in a development database. These are generally available to a development team for…
DBMS_OUTPUT is one of the most well-known and least understood SYS packages. If you have questions about how it works in general, you might want to read my previous post on the subject. What I want to show you today is a ‘trick’ that will help you bypass the step of enabling polling for DBMS_OUTPUT for all of your connections. I’m all about saving clicks, so let’s save you 3 clicks right now. Instead of…
I’ve answered this question a few times over the past several months, but I’m just now getting around to putting my answer onto ‘paper.’ The common scenario is someone decides to alter a table. Immediately the paranoid – is it really paranoia if someone is actually out to get you? – start to worry about how many programs they’ve just borked. The database does track immediate object dependencies. However, it’s possible that your code is…
I’m a keyboard ‘ninja.’ I know how to get a lot of characters to splat up on my screen in as few keystrokes as possible. Yet sometimes I do fall back to the mouse. Cue the command-line SQL*Plus diehards rolling over in their graves. One of my favorite tricks is the ability to drag 2 or more tables into the worksheet and have SQL Developer automatically create a SELECT with the WHERE clause joins pre-built…
Data Definition Language (DDL) is used to describe an object in SQL. When you model a table in your relational model using Oracle SQL Developer Data Modeler, you are probably very curious as to the code that is being generated to represent that object. You can peek into this code using your mouse – You can right-mouse-click on an object and choose ‘DDL Preview,’ or you can use the keyboard shortcut, Alt+Shift+I. Here’s trick #1:…
