Hi Thomas,
I setup a test against the latest version of OJB_1_0_RELEASE branch
using maxDB and hsql with an empty table.
public void testObjectByQuery_1() throws Exception
{
String dummy = "nothing_to_find";
Criteria criteria = new Criteria();
criteria.addEqualTo("name", dummy);
QueryByCriteria query = QueryFactory.newQuery(TestObject.class,
criteria);
Object result = broker.getObjectByQuery(query);
assertNull("We don't expect a result object", result);
}
All tests pass without problems. So we have isolate your issue (not
really ;-)): It could be a jdbc-driver problem or a bug in an older
version of OJB. If you can run the same test against hsql or another DB
we will find the answer (sorry, i don't have an old version of OJB at my
fingertips).
regards,
Armin

Hello there,
if we call
log = (Logbuch) broker.getObjectByQuery(query);
we get a NoSuchElementException.
At the moment because of a fresh database we know there aren't any records.
We're using Informix Dynamik Server 9.4 and Informix JDBC.3.00.JC1 driver.
I could imagine it is rather a jdbc driver problem but I don't know.
Any suggestions are welcome as always. :)
