I struggled with this for a while and could not find a clear example,
so I hope it helps someone out there.
I have a company object that has employees and employees could be
deleted (boolean property). So I wanted to search for all employees
for company X where the company is not deleted. It should be noted
that I have a bidrectional owned relationship setup between Company
and Person.
here is how I did it in JDO:
<code>
Key companyKey = KeyFactory.stringToKey(companyKeyString);
String queryStr = "select from " + Person.class.getName() +
" where company == companyParam && deleted == false";
Query q = pm.newQuery(queryStr);
q.declareVariables(Company.class.getName() + " companyParam");
persons = (List<Person>)q.execute(companyKey);
</code>
