We store the application settings PER user. So find where your OS stores files for your OS user. These settings are stored HERE on Windows (…AppData\Roaming\SQL Developer): They are stored HERE on Macs and *NIX ($HOME\.sqldeveloper): Find the directory that corresponds with the version you are running and having problems with. Rename it. Restart SQL Developer – you should be running ‘stock, out of the box.’ This can also come in handy any time the…
This isn’t a SQL Developer post, sorry folks. When it takes me more than a couple of Google searches and more than a little bit of poking around to figure something out, I reckon it’s blog-post-worthy. Maybe I can save you a bit of time too! I have: a 12.1.0.2 database the JSON patchset a table said table with IS JSON CHECK constraint some json docs that contain nested arrays So it looks a little…
Columbus didn’t exactly discover America. And we’re not really going to discover your long, lost foreign keys. But, we’ll do our best to guess where they might be. Our data modeling tool is often the bearer of bad news – your database doesn’t actually have any referential integrity defined. Oh, it’s defined somewhere, in the application. Probably. Just not in the database. (I realize these aren’t complete sentences, but this is a blog post, not…
Do you know someone who helps make our data safer, and more useful in the Oracle Database space? This could be an architect, engineer, data modeler – whatever, that works in the design area and shares their work and insight with the rest of the community. Someone who has something much more interesting to say than me: Please don't name your tables "FROM"— Jeff Smith (@thatjeffsmith) August 11, 2015 Oracle is hosting a Database Developer…
Today’s question: can I design a table that takes advantage of the new Temporal Validity feature in Oracle Database 12c? Today’s answer: ‘Yes.’ In a nutshell: Temporal Validity Support lets you associate one or more valid time dimensions with a table and have data be visible depending on its time-based validity, as determined by the start and end dates or time stamps of the period for which a given record is considered valid. Examples of…
Had a real fun time showing off a series of tips & tricks yesterday, and we did it all in 15 minutes! I can’t afford Mike Rowe or Morgan Freeman for voice over talent, so unfortunately this video has my voice. The things I show in this video, in blog form: SQL History Recall SQL Code Templates Joining multiple tables in a SELECT Query Builder Code Snippets Completion Insight SQL Text Expansion I hope my…
Someone asked in our forums how to format their code the way they want it. Specifically, they have code like so: 464641865662a0e7a10c33_000007 They don’t want this: The user doesn’t want the first predicate on the same line as the ‘WHERE’ keyword, and doesn’t want the additional predicate clauses to be on the same vertical position as the WHERE keyword as well. Thankfully there are 2 Formatter preferences that make this easy to fix. So the…
Working on some cool demos around JSON, ORDS, Oracle Database, JavaScript apps, etc. and I needed to load up a BUNCH of data to play with. Note the ‘other_tags’ column LOOKS like JavaScript Object Notation (JSON). There are JSON standards – should the key name and value strings be double or single quoted, etc. To ID text as JSON in Oracle it needs to pass our test. Also, you need Oracle 12c, specifically 12.1.0.2 (and…
I love performing my tips & tricks session. No two talks are alike. I frequently update the slides and content to account for new things I’ve learned and new features we’ve added. But. I’ve been delivering this talk going on 4 years now. Should I let my talk at Open World 2015 be my last hurrah of this topic for awhile? Maybe do more talks on Oracle Cloud, REST, data modeling, reporting, tuning, database administration,…
This is one of the features I showcased in a webcast yesterday – looking for a particular column definition in your relational model? We make that easy in SQL Developer. And, after you find all of these columns, you can quickly change them, all in one fell swoop. Ctrl+F in a model to open the search. Toggle to ‘Advanced.’ Set your search area and criteria. Hit the ‘Search’ button. Review the results, save as a…
