- JAVA JDO: Put in flag to convert '_' to CamelCase names in Java conversion
- Added possibility to specify the SQL terminator.
- Support for different sql dialects in SQL editor highlighting... read more

Druid 3.6 and roadmap

Hi to all,

after one year I have managed to bring a new release. This is mainly a bug fix release with some little news (see the changes section on the home page for more details). I'm sorry for not having added all patches but I don't have time to follow druid now.

This consideration lets me introduce a new choice I have made that is related to the roadmap. I have already started to code
druid 4 but this task will require a *lot* of work due to the features I want to add, like:... read more

Future druid releases will be focused only at bug fixing and module enhancements and they will belong to the 3.X branch. This will give me some time to code druid 4.... read more

I have decided to protest against software patents so I have changed the druid's home page.

I invite other developers to do the same

Druid 3.0 final released

After a month of beta testing, the 3.0 release is finally out. This is mainly a bug fix release with only a few adds: a new PDF doc gen module and localization of the XHTML doc gen module (see changes in the files section). All the docs have been moved from HTML to PDF to be printed and have been revised and improved. Druid is a tool that helps the dba/developer to handle database tables. Users can add/modify/delete database objects (fields, tables, etc...) using a GUI. When the db structure is complete, druid can generate the sql-script and docs in various formats.

Project Freeze

I'm sorry but I must freeze the druid project for at least one year. I have some business to do and I cannot spend more time on it. I hope to be able to release some minor enhancements in the future.

Patch for PostgreSQL and MySql

David Croy made some fixings and improvements to the release 2.7 that let users use the jdbc access with postgresql and mysql.
Note that to use postgresql you must use the development driver supplied with this patch.


Here are the release notes from David:

* Various fixes to work with postgres and mysqlj dbc drivers.
* Added a Row field in the data query panel. This allows for setting the max rows for a query.
* If a table has more than four columns add Horizontal Scrollbars.
* Don't query the data from a table until the data tab is selected.
* Moved AbstractLang.java to druid.interface. Allows modules outside of the druid package and use it.
* Added the remarks column to the table structure.
* Added a mysql comment type.
* Added a mysql and postgres sql generator. The postgres one allows for adding the descriptions to the database.
* In the Options->Generation. Enable the options button if needed.
* Created and ant build file.
* Include a development version of the postgresql driver. (It works for me YMMV).

First, I would like to give credits to Guillaume Dflache who wrote the druid 1.0 to 2.5 converter. I tried many times but I can't add notes to a release (SF problems).

Second, Druid 2.7 is almost complete. The only lacking features are the table's data import / export facilities. You may be wondering why I named this release 2.7 instead of 2.6. Well, there are some other improvements (there is a powerful record editing facility) and a new plug-in architecture regarding data generation. Now users can write small java classes to generate data in the format they want / need. Maybe I will release this at the end of june (I don't know).... read more

New Contrib package

I have added a "Contrib" package to contain stuff created by users. Feel free to send me your druid related stuff.

Pre releases in CVS

I have added the "pre" directory to the CVS where you can find development releases. Each release has its own dir which contains two files:

- druid.jar (must be copied on the old one)

- versions.txt (contains a list of changes)

Now, there is only the 2.5.x dir that contains the release from the 2.5 to the 2.6 release

Druid and PotgreSql

As told before, the PostgreSql JDBC driver doesn't work with Druid.

I was mailed by the authors of the driver because they are working to solve this problem so wait for the next driver release !!!

synonyms, procedures, functions, schemas), perform queries,
edit table data, save results to a csv file.
You can also send your druid project to the jdbc db to rebuild
it "on the fly" and perform some basic operation on the jdbc db
(drop of objects, refresh)... read more
