Firebird Conference 2011

The Firebird Project invites all Firebird users and developers to participate in the Firebird Conference 2011, which will take place in Luxembourg, November 25-26, 2011. The conference will be devoted to a variety of important topics: Firebird SQL language improvements, performance, optimization, database protection and recovery, and many others.

Schedule, topics and other details:

Letter from President of Firebird Foundation

Please read the letter from Philippe Makowski, the president of the Firebird Foundation:

Dear Firebird users,

You probably know that we are in the lucky position to have highly skilled developers working full-time and part-time on the further development of our favorite database, Firebird. A database that you can (and do?) use and distribute for free, that saves you and your customers from all the hassles that come with selling and administering licences.

The Firebird Project developers receive grants from the Firebird Foundation, a fund-raising foundation that was founded nearly ten years ago. The Firebird Foundation is collecting money through memberships, sponsorships and donations.

By becoming a member or a sponsor, or even by doing on-time donations once or from time to time, you can contribute to the further development of Firebird. Especially those of you who use Firebird for commercial, educational or governmental applications will understand that only a database that is under development can be used for serious work.

So, please think about becoming a member or a sponsor. There is something that will fit your possibilities (a basic membership is only USD 50/year). You can find more information at

Thank you.

Best Regards

Philippe Makowski
President, Firebird Foundation

Firebird Developers Day in Brazil

Speaking about conferences, in this first issue, we will present you a short story about one of the most important Firebird events in the world: the Firebird Developers Day, an annual Brazilian conference. We contacted Carlos H. Cantu, the organizer of the conference and asked him to write a short article about it, that you can check below:

FDDThe Firebird Developers Day happens annually in Piracicaba, a city distant 160km from São Paulo, mostly surrounded by sugar cane plantations, cut by a famous river (Piracicaba River, there is even a well-known music in Brazil about it) and with a population of 350,000 people. The city has several big companies installed, like Caterpillar, Belgo, Hyundai, etc. and is served by the best highways of the country. For the conference, we use an awesome structure composed by a theater with capacity for 800 people, and two rooms for 200-270 people each, in the Unimep University.

The idea of creating the Firebird Developers Day came after a sucessfull experience organizing the DDD (Delphi Developers Day) with DUG-BR (Delphi Users Group Brasil, where I was the president). Altough the DDD's were organized by DUG-BR, the FDD was (and still is) entire organized by myself. The first edition had the presence of 400 attendees, making FDD the biggest Firebird conference in the world (regarding number of attendees) from the beggining.

The second edition of the conference was really special, since it was the first to have the presence of international speakers: Ann Harrison and Jim Starkey got a very warm welcome from the Brazilian Firebird’s community, which included even TV, radio and newspaper interviews! It is still the FDD edition with the biggest number of attendees — around 620 people!

Since the second edition, we always had the presence of international speakers in the conference, including core developers (Dmitry Yemanov, Vlad Khorsun) and some other well-known names, like Alexey Kovyazin and Dmitry Kouzmenko (from IBSurgeon).

More than an opportunity for the attendees to have access to a great technology knowledge, the conference is a big celebration of the Firebird success in Brazil, where people can exchange experiences with other users, and talk freely with the speakers during all the day. Also, it is the best chance to register/buy Firebird related tools and components, with the huge discounts offered by our sponsors and partners (sometimes, products were sold by less than 50% of the normal price!).

In the latest editions, attendees also had the chance to donate money to the Firebird Foundation. The donations are getting higher every year, and in the 8th edition, attended by 600 participants, we were able to collect USD 2,600!

Brazil is a huge country, and the conference attendees come from all over the place. In the past, we even had attendees travelling 48h by bus to participate, coming from the extreme north of the country (hopefully, flights are now much cheaper, so almost everyone can avoid such long bus trips).

A “location interactive map” with a partial view of this year attendees can be seen at
An interesting fact is that, different from what happened in other countries, Borland/Inprise/CodeGear/Embarcadero had sponsored almost all FDD editions, even in the time when Firebird was not officially supported by their tools.

You can find the on-line reports of every FDD edition, in English and Portuguese, with pictures, at

I wish to thanks all the speakers, attendees and sponsors, for their support all over the years. Without you, this conference would never be a such big success!

Go Firebird!

[October 30, 2011] Statement history dialog layout in Flamerobin

Milan Babuskov wrote on flamerobin-devel:

In the past week or so I have improved our statement history dialog to allow easier browsing. Now it shows the statements on the left and when you click them, you get the whole sql on the right. This makes it easier to inspect the statements and find what you looking for. Especially if you have a large monitor. Also, the searched term is marked with red color.

I also added the timestamp of the history file. Functionality is now good, however, now I'm not sure about this layout. What do you think?

[October 25, 2011] Adriano Fernandes added new Window functions from the SQL:2008 standard

From twitter:
I remember when I added the LOWER function to Firebird. I needed to grep (for nod_upper) and change dozens of files...
Now to add even a window function (which the framework is prepared to) it takes just a few localized changes
Now adding LAST_VALUE and NTH_VALUE.
You can read more about the list of window functions that are already implemented or needs to be implemented on the tracker.

A short description of what these functions do:
  • first_value(value any) return value evaluated at the row that is the first row of the window frame
  • last_value(value any) returns value evaluated at the row that is the last row of the window frame
  • nth_value(value any, nth integer) returns value evaluated at the row that is the nth row of the window frame (counting from 1); null if no such row

[October 12, 2011] Command line manuals updated for Firebird 2.5.x

The various command line manuals — gfix, gstat, gsec, gbak and fbmgr — have been updated to Firebird 2.5 specification. In the case of fbmgr it was only a few spelling mistakes that were corrected.

I've uploaded the html and pdf versions to the online repository. One thing I noticed when testing, the PDFs are ok but the HTML files seem to need a refresh on every page. Has anyone else noticed this when a new HTMl documents is uploaded?

Try hitting this link and see if you get the 11 October 2011 version. If you don't see 11 October 2011, click refresh. Now click on the link to go to Command Line Options. Under the password option do you see a fetch_password option? If not, click refresh.

I found this morning that I had to manually refresh every page in each of the updated manuals — which I've never had to do before.
