Our customers, users, and followers are sharing their love for jOOQ to the world. Here are:

Thanks for the shouts, guys!

New license models – available soon

In the early days of migrating towards dual-licensing, we’ve discussed many alternative licensing models with our long-term users and early adopters. Now, we’re almost ready to publish the new, additional license terms, which are due for next week. They essentially include:

  • The existing yearly subscription for default use-cases
  • A new monthly subscription for short-running tasks, such as DB migrations
  • A new major release perpetual license for long-running jOOQ integrations with little need for upgrades

With these options, we believe that we will be able to cover even more jOOQ integration use-cases from a legal perspective, helping to further improve your jOOQ experience.

Are you an existing customer of the jOOQ yearly subscription interested in a switch to other terms? Do not hesitate to contact sales for a tailor-made migration offer.

Java Zone – Java 8 is out

Java 8 has finally been released by Oracle, a moment we’ve been waiting for quite a while now. Unsurprisingly, blogs in all corners of the web have started publishing Java and Java 8 related articles. We absolutely agree with Craig Buckler claiming Java to be the best programming language to learn in 2014.

Want to stay up to date with examples, tutorials, insights on Java 8? Follow ourJava 8 Friday blog series, then. Every Friday, we’re publishing an insightful article on a specific area of Java that will be affected by Java 8. One of the most interesting articles that has even caught the attention of Erik Meijer is Dr. Ming-Yee Iu’s guest post about JINQ and JINQ-to-jOOQ, which you should be looking out for in the next 6 months.

SQL Zone – In-Memory Computing

Do you know your fastest way around in-memory computing with Oracle? It’s possible, but it’s not so trivial.

If you’re used to SQL Server, you would simply create a T-SQL temporary table, which is a typesafe in-memory table for use with procedural T-SQL.

In Oracle, you have two choices to do the same:

  • Using SQL TABLE OF OBJECT types
  • Using GLOBAL TEMPORARY TABLEs

In almost all cases, GLOBAL TEMPORARY TABLEs will outperform TABLE OF OBJECT types for a very simple reason: You can perform all operations in the SQL engine only, whereas with TABLE OF OBJECT types, you will have to resort to the PL/SQL engine to keep the table in memory. With significant amounts of data, this can become quite a problem.
