Hi:
When I use HQL to do some date related query,I meet some problem which I can not find any answer after I read the HQL part of the hibernate manual and search from google,so I ask here for your guys's help.:)
Things are strange,it seems that the error result from the Query.setDate(xx,xx);
Main codes:
Code:
//test 1
@Test
public void testUsingDateObject() {
Session sess = factory.getCurrentSession();
sess.beginTransaction();
hql = "select en.name, count(en.name) from Entity en where en.time between ? and ? group by en.name";
Query q = sess.createQuery(hql);
q.setDate(0, start);
q.setDate(1, end);
List<?> list = q.list();
printHibernateList(list);
}
//test 2
@Test
public void testUsingDateString() {
Session sess = factory.getCurrentSession();
sess.beginTransaction();
// the start_str and end_str is built by new simpleDateFormat("yyyy-MM-dd HH:mm:ss").format(...)
hql = "select en.name, count(en.name) from Entity en where en.time between '" + start_str + "' and '" + end_str + "' group by en.name";
Query q = sess.createQuery(hql);
List<?> list = q.list();
printHibernateList(list);
}
private void printHibernateList(List<?> list) {
for (Object obj : list) {
if (list.size() < 1)
System.out.println("no result");
Object[] properties = (Object[]) obj;
String name = properties[0].toString();
long num = (Long) properties[1];
System.out.println(name + ": " + num);
}
}
The test 2 works well,and I got the following error when I run test 1:

--------------------------------
The reason I say it is strange is that the same code worked well a few days ago,and I just integrate the struts2 in my application,is it the problem?
