Body
I wrote a GPL'd solution for OMERO which you could easily build suited to your situation. <ul> <li>Source: <a href="http://trac.openmicroscopy.org.uk/omero/browser/trunk/components/server/src/ome/tools/hibernate/QueryBuilder.java" rel="nofollow noreferrer">QueryBuilder.java</a></li> <li>Test: <a href="http://trac.openmicroscopy.org.uk/omero/browser/trunk/components/server/test/ome/server/utests/QueryBuilderMockTest.java" rel="nofollow noreferrer">QueryBuilderMockTest</a></li> </ul> Usage: <pre><code>QueryBuilder qb = new QueryBuilder(); qb.select("img"); qb.from("Image", "img"); qb.join("img.pixels", "pix", true, false); // Can't join anymore after this qb.where(); // First qb.append("("); qb.and("pt.details.creationTime > :time"); qb.param("time", new Date()); qb.append(")"); qb.and("img.id in (:ids)"); qb.paramList("ids", new HashSet()); qb.order("img.id", true); qb.order("this.details.creationEvent.time", false); </code></pre> It functions as a state machine "select->from->join->where->order", etc. and keeps up with optional parameters. There were several queries which the Criteria API could not perform (see <a href="http://opensource.atlassian.com/projects/hibernate/browse/HHH-879" rel="nofollow noreferrer">HHH-879</a>), so in the end it was simpler to write this small class to wrap StringBuilder. (Note: there is a ticket <a href="http://opensource.atlassian.com/projects/hibernate/browse/HHH-2407" rel="nofollow noreferrer">HHH-2407</a> describing a Hibernate branch which should unify the two. After that, it would probably make sense to re-visit the Criteria API)

Guidance

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.
