PLSQL: Nice little overview of the PL/SQL language

I just came over these slides and nice little overview of the PL/SQL language by Morten Braten. The slides covers many good tips to follow when coding PL/SQL. It’s not ment to be an introduction to the PL/SQL language, so many topics are just mention briefly and would need to be followed by further reading and/or investigation. But it is definitely worth a look!

MacOS: Finally a text editor competing with Notepad++

There is only one thing I used to miss from my Windows environment – Notepad++. After switching to Mac and OSX I have been looking for an alternative. For a while I was using Atom, but did not really find it efficient. So I often ended up using the default TextEdit utility.

The other day I got a tip from a Java developer at Bouvet. He was using Visual Studio Code 2 (https://code.visualstudio.com/) . I have used this for two weeks now, and is very very happy with it. Finally a text editor which beets Notepad++.

Java and JDBC for Oracle DBAs – Part 3: Git, Oracle schemas and your first Java application

Finally we have come to the point where we start to create some Java code. First we’ll install Git, the most widely used modern version control system. We’ll continue to download some code from GitHub to create our Oracle schemas, and then we’ll create a very simple – but our first – Java application. We’ll test compiling and running our code both from Eclipse and from Maven. Finally we’ll extend our application to use the JDBC driver and connect towards our database and our new database schemas.

Java and JDBC for Oracle DBAs – Part 1: Oracle Database in Docker

Working together with Java developers I sometimes have to test aspects of the JDBC programming. When cooperating with the Java developers it is also very convenient to know some Java. In this blog series I’ll describe how you can build your own Java test application, and how you can get a little more acquainted with the Java world. The blog series will not be a tutorial in Java. You can find several Java tutorials on internet (for instance – https://docs.oracle.com/javase/tutorial/).
