Using Java ORMs with PostgreSQL – MyBatis

March 12, 2018 /6 Comments/in 2ndQuadrant, Umair's PlanetPostgreSQL /by Umair Shahid

In my previous blogs, I wrote about Hibernate Query Language (HQL) and Querydsl in detail, now I’m going to talk about MyBatis. While ORMs typically map Java objects to database tables (or vice versa), MyBatis takes a different approach by mapping Java methods to SQL statements. This gives you complete control over writing SQL and its […]

PostgreSQL 11 – Server-side Procedures (Part 2)

February 16, 2018 /7 Comments/in 2ndQuadrant, Umair's PlanetPostgreSQL /by Umair Shahid

Transaction control in PL procedures A couple of months back, I wrote about how we now have the ability to write Stored Procedures in PostgreSQL. This post follows up on that and talks about the next step that was implemented: transaction control in PL procedures. The feature was committed on 22-Jan-2018. With this addition, you […]

PostgreSQL 11 – Server-side Procedures (Part 1)

December 7, 2017 /12 Comments/in Umair's PlanetPostgreSQL /by Umair Shahid

Last week marked a rather big step in the PostgreSQL world that went largely unnoticed. Thanks to the work done by 2ndQuadrant contributors, we now have the ability to write Stored Procedures in PostgreSQL! (Ok, well not exactly now but we will have the ability once PostgreSQL 11 comes out) A procedure is essentially a […]

v10, The Best PostgreSQL Yet?

October 5, 2017 /1 Comment/in Umair's PlanetPostgreSQL /by Umair Shahid

The short answer … Hell Yeah! The long answer lies in extensive improvements and the impressive new feature list that makes up this major release – which, by the way, changes the version scheme of PostgreSQL as well (more details on that here). This wiki page lists out, in detail, all the new features in […]

JOOQ Object Oriented Querying (jOOQ)

August 18, 2017 /2 Comments/in Umair's PlanetPostgreSQL /by Umair Shahid

jOOQ is an ORM-alternative that is relational model centric rather than domain model centric like most ORMs. For example, while Hibernate lets you write Java code and then automatically translates it to SQL, jOOQ let’s you write relational objects in your database using SQL and then automatically generates Java code to map to those relational […]

2ndQuadrant – Not the Gartner Magic Quadrant

April 3, 2017 /0 Comments/in 2ndQuadrant /by Umair Shahid

It’s still appropriate though. Because that is what we are – thought leaders in open source PostgreSQL. But that’s not what I am here to talk about. The name “2ndQuadrant” comes from “The Seven Habits of Highly Effective People” by Stephen Covey, specifically Habit 3 “Put First Things First”, p.151. It refers to the classification […]

The PostgreSQL License – What Does It Mean For My Business?

December 13, 2016 /7 Comments/in Umair's PlanetPostgreSQL /by Umair Shahid

When I talk to various people about PostgreSQL, based on where they are in the process of analyzing it, I get asked many similar questions. One of the most frequently asked questions is: What is the PostgreSQL licensing model? Here is my attempt to address this question from the perspective of what the PostgreSQL license […]

CHAR (16) – Another conference on the horizon but with a focus on business

November 2, 2016 /0 Comments/in 2ndQuadrant, Featured, Howard Postgres Marketing World, Howard's PlanetPostgreSQL, United States News /by Umair Shahid

The PostgreSQL user community is becoming spoilt with a choice of excellent events organized by both local user groups and commercial organizations supporting the PostgreSQL project.  And amongst the events taking place in December, the one you definitely shouldn’t miss attending is CHAR(16). ‘CHAR(16): Scalability for Business’ is intended to fulfill a different requirement – different […]

2UDA – Installing PostgreSQL 9.6 the easy way

October 4, 2016 /0 Comments/in Umair's PlanetPostgreSQL /by Umair Shahid

PGDG announced the General Availability of PostgreSQL 9.6 on the 29th of September. Like each year, this new release brings with it a lot of exciting new features. Using these features, of course, requires installing PostgreSQL … a task that can be a touch daunting for novice users. 2UDA, a graphical installer for PostgreSQL, is designed to […]
