You have a new version of SQLcl to download this morning. Lots and lots of bug fixes – again, thanks everyone in the community for providing feedback so we can make continuous improvements. A few things of note: Two New Commands They do pretty much what you’d expect. You’ll also notice something new on startup/connects if you’re using a ‘local’ LOGIN.SQL What’s a ‘local’ LOGIN.SQL? It’s a LOGIN.SQL file that we find in your current…
Yesterday I talked about how to grab the output returned from your stored procedure when executing via Oracle REST Data Services. The example was: INSERT a new record into a table. Return the new employee ID and the total number of employees in the table. So we just needed 2 parameters for our handler to catch the two integers returned, easy-peasy. But, what if we were going to return the entire record? So let’s write…
PL/Scope is one of my favorite features. It answers SO many questions. Where am I declaring this, where am I calling that, when am I referencing something? And, I can get this information automatically, without hitting the big, fat SOURCE data dictionary views. I’ve talked about this previously… …BUT, PL/SCope didn’t help me with tracking the SQL I used in my PL/SQL. That is, it didn’t until 12cR2. Starting with Oracle Database 12c Release 2…

Want to export a ton of tables, but only get SOME of the records? Want to apply a GLOBAL filter across the tables to only get the records you want? Tools > Database Export. I’m going to export data, NOT DDL. I’m going to write it to a single JSON file. I’m going to grab data from a couple of tables. I ONLY want records from those tables where the CUSTOMER ID is in a…
Many of you might not know that most of what you can do in SQcl, can also be done in SQL Developer version 4.2. In fact, it’s the same code that handles running statements/scripts in SQLcl as it is in SQL Developer’s SQL Worksheet. Assuming of course, that you use THIS button. There’s one large exception to this. TODAY: we don’t allow you to use the SCRIPT command, yet. And one small exception: you can…
Reviewing my timeline, I came across this gem from Franc. I hate seeing SQL with keywords in uppercase and identifiers in lowercase. identifiers are case sensitive. Not keywords.— Franck Pachot (@FranckPachot) February 7, 2017 Franck isn’t alone – a lot of people hate it when their code doesn’t look the way they want it to. Many folks know about our formatter, and how to use it to get their IDENTIFIERS UPPER-CASED. But did you know…
A friend, let’s call her ‘Helen’ for the sake of this post, texted me the other day, wondering why she had all these dozens/hundreds (?) of files in her Windows home directory. She was confused. Where did they come from? Were they safe to delete? I asked her what they were called, and the filename sounded VERY MUCH like what she would have named her SQL Developer connection for a particular database. Now, it might…
Let’s say you have some files, stored as BLOBs, in your database, and you want to make them available via REST. So of course you install Oracle REST Data Services, and now you have two options: REST Enable the table or Deploy a custom RESTful service With the first option, I get an ‘automatic’ REST endpoint for my resource, which in this case is my table that has the BLOB, but I don’t want or…
Remember this fancy do-hickey? It’s the Instance Viewer. We introduced it as a new feature in version 4.1. For version 4.2, we added this – the Top SQL panel. We ask the database every 10 seconds what the most expensive query by CPU is. Maybe that’s a bit too aggressive for you? What if you only wanted to ask every…10 minutes? You can do this. You’ll want the Instance Viewer to be open and running,…
