Ever seen a table with so many columns you wonder if the designer had fallen out of the de-normalization tree and had hit every branch on the way down? Oracle currently allows a max of 1,000 columns per table. Please do not test this limit. Maybe you do need that many columns, but I doubt it. If you were to visualize this data model, imagine how easily you might be overwhelmed with all the white-noise,…
View – Recent Objects will show you a list of objects you have click into via the explorer. If you need to keep a diary of objects you’ve messed with for the day, then this might do the trick. No, it doesn’t track what you did to the objects, but it does leave some bread crumbs for you to snack on later. You can invoke the object action lists directly from the panel, or if…
So you’re in Tweetdeck and someone mentions you in Portuguese or Swedish. You have no idea what it says, but you’re pretty sure it’s not a compliment. Thank goodness there’s the one-click ‘translate’ feature to bail you out. It’s often saved me from my elementary Spanish. How many times have you used Google’s translation services for help getting something from Korean to English? I have many times. Now, how nice would it be if you…

You execute your program, you create a local variable or 3 to ‘catch’ said output, and…
There are many good articles out there that go into detail for creating reports with Oracle SQL Developer. I was reading my predecessor’s write up in Oracle Magazine (May 2007) on the subject, and keyed into the following snippet: Building a Chart When creating a report with the Chart style, the rule of thumb is to use SELECT group, series, data FROM table . So the basic tabular report you created earlier also has the…
I’ve already discussed how the Rebel scum go about figuring out what’s wrong with their code. Now I want to get into the nitty-gritty details of how to start a debug session in SQL Developer. There are some prerequisites, but I promise it won’t take but a few moments to setup. Ensure that you have been granted the DEBUG CONNECT SESSION priv you have EXECUTE privs on DBMS_DEBUG_JDWP you have EXECUTE privs on the object…
When I’m doing my ‘Tips and Tricks’ show, there is at least one trick that is guaranteed to get the audience’s attention: I’m in an editor – INSERT MAGIC – wham! I’m cycling through the SQL History list, no need to use the mouse. Here’s a set of keyboard shortcuts I want you to memorize RIGHT NOW:Ctrl+Down — NextCtrl+Up — Previous The concept of ‘Next’ and ‘Previous’ will depend on the sort order defined in…
Can you tell us more about the debugger? Can you show us the debugger? What about the debugger? Can you spell ‘debugger’? Why can’t the debugger show X? What is COMPILE WITH DEBUG anyway? Debugger? Skip to Episode V – Starting the Debugger In the past 10 years I have probably heard these questions and countless variations more than any other when it comes to the topic of PL/SQL interactive development environments (IDE.) Debugging seems…
How deep do you go in your software? Do you make it at least 1 click deep? I’m talking about right-clicking with your mouse. Software folks are often accused of hiding things on context menus, but you have to remember that software is engineered and developed by folks that are comfortable with computers – and we just assume everyone knows to ‘right click everywhere.’ You may have noticed something was amiss when you first used…
