Query on AS400/DB2

Question

Hello,
I am using kodo2.5.0 with the DB2 for OS/400 JDBC Driver.
The following simple code return empty result.
Transaction tran = pm.currentTransaction();
tran.begin();
Query qry = pm.newQuery(Customer.class, "name == \"Mark\"");
Collection result = qry.execute();
System.out.println("Size = " + resutl.size());
tran.commit();
The size SHOULDN'T be zero.
but the following code return the correct obj.
Transaction tran = pm.currentTransaction();
tran.begin();
CustomerId objId = new CustomerId("Mark");
Customer customer = (Customer)pm.getObjectById(objId, true);
tran.commit();
Both codes work fine against DB2 on Windows. only make differents on
DB2/AS400.
The JDBC driver for AS400 should be fine. It works fine for JDBC,
PerparedStatement etc.
It seems all the queries do AS400/DB2 returning emtpy collection.
Is there anyway I can see how many rows get back
from DB by using Kodo?
Any hints are welcome.
Thanks,
pike

Hello,
i had the same problem (also DB2/AS400 and kodo2.5.2). After setting
com.solarmetric.kodo.DefaultFetchThreshold:-1
in kodo.properties it worked.
hope it help,
