    <blockquote> <p>Basically, creating each entity programmatically (...) is too unwieldy given the data model and the populate.sql script we already have written (and is executed on DB2 for running our JBoss-hosted web site locally) can't be used on Hypersonic!</p> </blockquote> <p>If you want to reuse your SQL script, you could try H2 with the DB2 compatibility mode, <a href="https://stackoverflow.com/questions/3919613/for-testng-what-is-the-proper-method-for-pre-populating-the-data-source-containi/3920528#3920528">as suggested by @Arthur</a>. If it doesn't work, try JavaDB/Derby, which is DB2's language compatible and can also be used "in-memory".</p> <p>But if the script is huge, I'm afraid tests will be pretty slow. In that case, using DbUnit and smaller dataset could be an alternative. Have a look at the built-in <a href="http://docs.jboss.org/seam/2.2.1.CR2/api/org/jboss/seam/mock/DBUnitSeamTest.html" rel="nofollow noreferrer"><code>DBUnitSeamTest</code></a> and <a href="http://relation.to/1420.lace" rel="nofollow noreferrer">Functional testing with Seam, DBUnit, and TestNG</a>.</p> <p>And if you go the DbUnit way, you could use a tool like <a href="http://databene.org/databene-benerator" rel="nofollow noreferrer">databene benerator</a> to <a href="https://stackoverflow.com/questions/591892/614382#614382">generate mock data</a> and then dump them as DbUnit dataset (there is <a href="http://databene.org/benclipse.html" rel="nofollow noreferrer">an eclipse plugin</a> to ease this task).</p>

    1. CONice. Post in your own answer the tool which can **generate data for the target database**. Once you have point out but i do not remember its name. Maybe it can help @Afterglow

    3. CODiscovered H2's "DB2 compatibility mode" is nothing but: http://derekmd.com/2010/10/h2-and-db2-incompatibility-mode/ I ended up moving all my tests over to DBUnit, creating a new populate.xml by hand that used test data separate from our development insertion SQL script. In the larger scheme, it's not ideal but at least we now have an efficient test suite. Thanks.

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
