hi wallace,
it's not necessary to join manually, ojb will do it for you:
Criteria crit = new Criteria();
ReportQueryByCriteria q = QueryFactory.newReportQuery(A.class, crit);
q.setAttributes(new String[] {"xxx", "yyy", "rel_b.zzz" });
Iterator it = broker.getReportQueryIteratorByQuery(q);
there must be a relationship-definition from class A to B named 'rel_b' in the
repository.

Hello,
I tried the following code to select a join, but get error:
Criteria crit = new Criteria();
crit.addEqualToColumn("A.xxx", "B.xxx");
ReportQueryByCriteria q =
QueryFactory.newReportQuery(A.class, crit);
q.setAttributes(new String[] {"A.xxx", "A.yyy",
"B.zzz" });
Iterator it = broker.getReportQueryIteratorByQuery(q);
( In the case, for string "A.xxx" or "B.zzz", what name should I use as
A or B? The physical table name or class name represented or other name?)
SQL statement:
SELECT A.xxx, A.yyy, B.zzz
FROM A JOIN B
ON A.xxx = B.xxx
Please help!
Thanks!
Wallace
