The results browser will be displayed whenever a query is executed with the "Execute Query" option (see Section 8.5, “Execute Query”). The results is a combination of a tree and a table. The table contains a read-only view of all the primitive or String fields of the candidate instances that result from the execution of the query. On the leftmost side is a tree pivot that allows you to "dig" into the object, revealing individual rows for each of the fields of the object. Child collection fields can also be opened, which allows you to traverse your persistent object graph to an arbitrary depth. The browser is useful to see the exact results from the database, as well as ensuring that your mappings for relations are set up correctly.
It is possible to drag persistent entries from the class into various components of the JDOQL editor. For details, see Section 8.4.2, “Parameters Editor”.
