----------------------------------------
I execute the java code to generate consultation for RuaBean:
Session ses = HibernateUtil.getSession();
String hql = "from RuaBean order by tipoRua.nomTipoRua";
Query query = ses.createQuery(hql);
List list = query.list();
for (int i = 0; i < list.size(); i++) {
RuaBean rb = (RuaBean)list.get(i);
System.out.print(rb.getCodRua()+" - ");
}
The result is: 79 - 49 - 77 - 1 - 86 - 85 - 38 - 62 - 88 - 87 - 1 - 68 - 66 - 84 - 70
It's ok. But if use pagination:
query.setFirstResult(0);
query.setMaxResults(10);
This result is: 85 - 86 - 77 - 49 - 1 - 79 - 1 - 84 - 88 - 68
query.setFirstResult(10);
query.setMaxResults(5);
70 - 84 - 88 - 68 - 66
The sequence is totally wrong, it should be:
79 - 49 - 77 - 1 - 86 - 85 - 38 - 62 - 88 - 87 for the first consultation with pagination
and:
1 - 68 - 66 - 84 - 70 for second.
In the second, see that three values if they repeat.
This mapping of class RuaBean:

it is oh all of the classes and mappings envolved. Thank you.
Bug Oracle9iDialect Pagination
------------------------------
Key: HHH-3292
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3292
Project: Hibernate3
Issue Type: Bug
Components: core
Affects Versions: 3.2.6
Environment: Java2 6.0, Oracle 10i, Hibernate 3.2.6
Reporter: Mizael Montenegro
Priority: Critical
Original Estimate: 1 hour, 30 minutes
Remaining Estimate: 1 hour, 30 minutes
Hi, I found a flaw in the dialect of the oracle, the pagination doesn't work
correctly, my English is terrible, then I cannot describe the complete problem here, more
I will post the string sql that solves the problem.
select * from ( SELECT x.*, rownum as r FROM ( "CONSULT SQL" ) x ) where r
between ? AND ?
setInt(1, BEGIN);
setInt(2, END);
I altered the dialect and it perfectly worked with that solution. The largest problem is
when ordination, the order is used using pagination corresponds never to the exact return
of the original consultation.
