I have connected to sybase database by jdbc driver,but when i try to execute the follow codes :
//m_sessions is SessionFactory Object
Session session = m_sessions.openSession();
String str = "select count(*) from Event";
Object obj = session.iterate(str).next();
when debuging to the last line code,there is no any reaction,and also there is no any return value in the obj,it seems like the programme halting,in fact,the obj should contain the number of records in Event.I dont how to resolve it.
Urge for good suggestion!

When I execut the same codes in MySQL,it retruns the expected value,so i'm confused whether it's the sybase configuration problem?But i've searchd on the web,it seems not much case using Hibernate in connecting sybase DB,so i doubt the performance of hebernate connecting sybase.

surround with try catch block and log + have a look at the Hibernate logs

i've got it,because i create table in database master,however the space of master is limited,so when i insert new record in database, it's nearly full.so the storing procession suspends!
