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…
Bequeath is an interesting word. It’s hard to pronounce for starters, or at least it is for me. So if you want to trip me up during a seminar, ask me about how to connect to Oracle sans Listener. Then you’ll get to hear me try to say bi-ˈkwēth, -ˈkwēth, bē- from Merriam Webster Your database hasn’t died (at least I hope it hasn’t, if it has, you’re in the wrong place). Instead, there’s a…
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:…
Incremental find. What is that? It is one of many features in SQL Developer that I have managed to overlook. It has been right there though, staring me in the face. I’m betting that many of you have seen it without really SEEING it, just like I have been doing. Until today that is! Let’s take a look at the word ‘incremental’ first: From http://dictionary.reference.com in·cre·men·tal [in-kruh-men-tl, ing-] adjective increasing or adding on, especially in…
It’s easy to forget that many people still have not discovered SQL Developer, or are just getting started. Many of my recent posts have been on advanced topics, hidden tricks, and productivity tips. I want to spend some time in the next few weeks helping the beginners out there. I can’t think of a better place to start than with how to ‘install’ SQL Developer. I’ve been telling anyone who will listen than you can…
You want to run a query or two against an Oracle database. You want to get the data back into a user-friendly and consumable format, such as a comma separated values file. You can do this in SQL Developer, VERY easily. You can watch the movie… …or read on – your choice! Quick ResultSet Exports as Script Output I’m too lazy to hit execute > SaveAs > Open File. I just want to get my…
Martin asks – I am searching for any method to pass any table name to a sql statement in a self-written report. My initial response was to quote Lewis’ article in Oracle Magazine where he discusses bind variables, Making the Most of Oracle Developer Reports. So binds work, but what about SQL*Plus Substitution Variables? You’ve seen these before: & – Input value and use once&& – Input value and use for entire session. The answer…
I’m poking around an unfamiliar schema or environment. I’m not sure what these procedures do. I could open them, but I’m lazy and I don’t want the tool to open another document/window. The ‘mystery’ code: These programs are self-documenting as they have the most awesome names ever! I’m guessing that one package will blast my enemies?, but I’m not sure. If only I could peek into the source without opening it!!! Hmm, what’s this thing…
SQL Developer is a pretty mouse-heavy tool. By that I mean that many of the functions are accessed via mouse-clicks. When browsing tables in the tree you may have noticed that you can expand a table node to display the table columns. There are some pretty cool features available under the context menu when clicking on a table column: Some of these actions are available under the table right-clicks, but a couple are not, ‘Encrypt’…
Updated: July 29, 2012 Defining what success means to you and your blog is something you have to do before you can answer questions like ‘Is this working?’ If you’re using your website or blog to sell widgets, it’s pretty easy to measure. Are we selling more widgets or do customers on average spend more per transaction, or do we make more money with less products – these are all pretty easy metrics to measure.…
