Someone on the innerwebs asked how to show the data inside their user defined TYPE’d column in a table when querying it with SQL Developer. Here’s their code: 13358592356629de22c4621_000000 Run the query. Get the results. Or, in the preferences, enable this: Run the query again.
You want the create script for a table. AND you want the create script for ALL of your tables. BUT also I want want the tablespace. Forget the constraints. How do you configure this in our tools? SQL Developer: The Preferences & the Wizards Go to the preferences. Database, utilities, export. SQLcl: SET DDL HELP SET DDL SET DDL And now run the DDL command. Don’t want the quoted identifiers? Use the Data Modeler.
SQL Developer has a DBMS Output panel you can open and add to your desktop. You then add a connection you want to poll, and then you enable polling. It’s about 4 clicks. If you want to increase the default buffer size from 20,000 characters, then that’s a few more clicks and keystrokes. A friend of the blog (Thanks Koen!)… Tweets by @koenlostrie … suggested I share his favorite trick: using a code template to…
We already have some pretty Spartan toolbars. We aim for fewer buttons, not less. But maybe you want to go SUPER Spartan. Even fewer buttons! Yeah, you can do that. View > Show Toolbars > Customize Main Toolbar > Customize I’m going to take a few things off the main editor and data modeler toolbars. Now you’ll get a popup window. Simply grab the button you don’t want anymore, and drag it onto the popup.…
I sometimes get a double-take when I do a blog post or tweet or show a picture of SQL Developer running on my Mac. My Macbook is my personal machine: I don’t normally do live-demo’s on it, but I almost always do my blog posts and screenshots from there. For official webcast stuff and conferences, it’s the old workhorse Win7 machine. And it looks like this for the most part: But you as a user,…
Here’s a quick run-down of FAQ’s I get when doing presentations or demos. Can SQL Developer… Extend a tablespace? Yes. You can edit an existing data file or add a new one. We’ll also show you the SQL that’s going to be used so you can copy it to run in SQL*Plus or wherever. And if you wanna just do it in a SQL Worksheet, we can help you with the syntax there too. Debug…
I have talked about how to preview BLOBs (Binary Large Objects) as pictures… But someone on Stackoverflow asked how to read a BLOB value if it had text. So I spooled the content of my EMPLOYEES table to a txt file, as CSV, and then loaded that to a table as a BLOB. Then I browsed the table, double-clicked the cell… and voila, the data being stored… Other BLOB posts: setting up external editors (Adobe…
I answered this question on Quora yesterday: What are the best resources for learning Oracle Database? The biggest learning curve to learning Oracle Database, SQL, PL/SQL, and all the other cool technologies that come with our database, is figuring out how to download, install, and create a database FIRST. And then of course you’ll have to configure a connection in either our command-line interface (SQL*Plus or SQLcl), our GUI/IDE (SQL Developer), or one of our…
This post is a tease. It’s also a request. Send me your ugly code. In version v4.2 of SQL Developer – to be released in calendar year 2016 – we’ll be offering a new formatter for your SQL and PL/SQL. It’s got a completely new engine under the hood. It’s faster. It’s more efficient. And it sounds really cool too – which is what most gearheads care about most. I’ve taken many, many, many requests…
Best practice for code readability dictates that your keywords should always be in: insert your preferred style here __________. Here’s a Twitter poll I’m running if you want to personally weigh in: Do you agree? Best coding practices dictate uppercase identifiers? https://t.co/WhOZvL2Bmv— Jeff Smith ☜ (@thatjeffsmith) March 16, 2016 So even if we can’t all agree on what’s best, we can all agree that our tools should help us get the code we inherit or…
