bug The right place for bug reporting or requiring additional features is


Since the project is new, it is normal to have something to fix. The problem is that my testing would just be not sufficient, so your help will really be appreciated. Thanks!

First of all I renamed the project on Sourceforge. Now it is more sensible NHibernate Workbench.


In the SVN repository there is now a tag to the version, and the trunk claim to be the version

Now I’m planning to allow to use NH Workbench attached to a running application: this should help us to play with application compiled without mappings ( ie ConfOrm and Fluent NH ). Then I would like to improve the “Probe” class letting it be more versatile and modifiable by the user, probably using some sort of script engine: I’m thinking to use IronPython, but any suggestion are welcome. Just to clarify: the probe class serves to insolate NHWorkbench from the NH version used by the project under test. We basically runs the test in a separate app domain, but we need the “probe” type to be unbounded to any NH specific version. This is done by using reflection, but it would be easier to be done in a script. The same engine will be useful to write some NHibernate testing: instead of use just HQL, we will be able to submit some portion of code on the fly and see what happen. The other step is to allow the user writing a mapping on the fly and imemdiately see what happen ( by using hbm2net behind the scenes ). Ok, it’s a lot of work, I’ve no idea the order this will be done, let me know if you have any idea and preference.

As you probably guess, the Fatica.Labs.HqlEditor evolved as a component used by NH Workbench, that is basically a tool ispired by the old and wise NHQA by Ayende. There is, in comparison, some new ideas and some missing required functions. Anyway I decided to publish a first drop because it already help me on my day job. If you find the project useful please consider visits the following links:

And, if you want to join the project, please let me know.

s9cThere is some interesting news with HqlEditor: now it is able to translate the query using the proper parser ( Antlr or Classic ) depending on the NH version used to build the assembly in test. An error message is shown when the syntax is parsed as invalid.








A first table containing the entities is present too, here below a screenshot:


As you can probably notice, the data grid is not a real grid. This is because is not so easy to present an NH graph without converting it in some sort of DTO, but I don’t want to add anything but the query process itself. So I decided to use a sort of JSON serializer to present each object in a textual fashion. In the toolbar there is the query limit too: this act by adding a SetFirstResult(), SetMaxResults() function call in the query creation. Using a count=0 forces the system to avoid limiting the query: if the data you retrieve is a big bounch you will probably experience some delay, but should be useful in the case the driver does not support limits.

There is some interesting progress with my project Fatica.Labs.HqlEditor. I just want to share some screenshot:


Well, it is growing to be a real tool, and in my idea would became a sort of test bed in which the user can add or modify mapping, try the queries, change the config, export a database script, reverse engineering and so on. Actually all the low level tool to achieve that are available.

Ok, let’s explain the layout:

  1. The document area, here we have mapping/config/hql all with intellisense. In the screenshot the code completion for an Hql is shown. In future maybe I will be able to insert a T4 editor for the hbm2net templates.
  2. The project area: here we have a bounch of file that are representing our testing project: mapping, configurations, assemblies and so on. I have use the MSbuild object as a backend for the project, because in the near future I would like to use it to really build some artifacts using hbm2net and db2hbm.
  3. Here is the SQL preview of the query in editing. Now the view is showing an error because the query is incomplete.
  4. The funny log, a graphical appender for log4net :-)

Some more words about the project itself: the testing environment is hosted in a separate appdomain, this will allow us to:

  • Modify the mapping runtime generating new version of the assembly
  • Testing production assemblies built with legacy nh versions ( well, not so legacy, starting from )

Let’s have another screenshot, showing a real SQL preview:


Next step is to produce the query results in some sort of usable representation ( I need to push the data across two app domain ) so I would probably use some JSON serialization and then display the JSON raw data with some readable formatting.

You can see a little demo video here.

The project is not yet released, please treat it as a CTP ;) anyway, the svn repository is here:
